REBIRTH OF THE BEAVER THREAD into the new HPA site

     I now have the Beaver almost done.    I kept building for five weeks since the Hip site went down Nov 26 2025.   My last post was Reply #318 on Nov 23 2025,  putting six pics into almost every reply.    I started this model June 13 2025,  so that is about 6 months worth of taking pics editing and writing text,  and blogging about my favorite hobby.   I will try and see what I can post out of all that now.   I still have my,  'now full',   Studio Notebook  9" x 6" of 250 ruled pages of diary handwritten Journal,  and I have just my own comments,  my own text,  and my pic numbering is saved for all of my replies on my computer.   So ....  it is possible to re-post a lot of the original build thread,  and lots that I could cut out also.   

     I would like to start off with some cool Beaver pics,  and then the kit contents after that.    For my build,  I pinned my two large plan sheets onto a  3/16" x 20" x 30"   white foam board (built up to  36" x 24" backing),  and I stood it up on my sofa chair,  and I just pin everything on it as I go,  so I can readily see it all the time.   The two pics of the two large plan sheets are not the greatest,   and I included  those  'rough'  plan pics,  so you can see the details and features of the model before you buy it.   And for whatever it is worth,  you get my kit review evaluation,  and build,  to refer to as well.

     I intended to build the Beaver exactly as per plan,  but I made a lot of changes in order to strengthen it up for free flight rubber powered landings,  in a Cricket field of  110 yards  by  130 yards,  slight oval.

     It was time to turn my retirement attention "span" to a new build.   I was looking for a new 30" high wing model to bash around and fly in the Cricket field of Jackson Park, Windsor, Ontario.

     The local hobby store,   Windsor Hobbies,  had one in stock .... a DH C-2 Beaver,  kit 306,  with over 80 laser cut parts.

      I now don't think I will put floats on it,  just because I will fly it in the park's Cricket Field.   But I just might put wheelpants on it.    I have a big sheet of  1/8"  balsa that I could use to make wheelpants parts from,  the same size of the wheelpants of my best flying model,  that I beat to death with many Flight reports and repairs -   my Dumas 30 inch Rearwin Speedster, which is now out of commission,  and all my Speedster Flight reports and detailed repairs are now gone into the ether with the recent final crash -  I can just trace out the wheelpant parts from the Speedster plan,  and they should fit.   I got a 42 sec flight from that Speedster.

     This is a great old documentary from the 1970s,  flying in the North of the Province of Manitoba (and monster lake Winnipeg).   The province of Manitoba lies just west of,  and right beside,  the province of Ontario,  Canada.

     Planes include  BrittenNorman2,  Beaver,  Otter,  Buck 80,  Buck 85 which is a Funk Model B,  Cessna206,  and Cessna207,  and the Norseman,  the poor man's Beaver.

     There is a lot of good reminiscing in the comments by old pilots ...

The definitive source of Beaver information is on Neil Aird's DH2 Beaver site
https://dhc-2.com/
He has a full listing of all 1,692 Beavers produced and photos of 1,288 of them. Many have details of their ownership and history.
As a mining geologist with over 50 years of bush flying in Canada's North, I have flown in many Beavers, some of which I can trace on his site.

     Hi JohnOSullivan!    Thanks for the link again,  and filling in that gap in my build thread!    I was just about to write how I lost all the contributions and pics and links from other modelers,  that helped make the Beaver an interesting topic.

     "As a mining geologist with over 50 years of bush flying in Canada's North, I have flown in many Beavers, some of which I can trace on his site."    Wow John!   8)    Please feel free to chime in any time with any stories pics comments links.   I was trying to make mining and rough air strips the theme for the  Alaskan Bush-Wheeled Beaver.   It would need a proper Diorama Mining-based theme, for a model show,  though.    Prospectors are the real deal as far as the outdoorsmen go.   I met a couple of them.   I digress.  ;D   You got me going ....

Reply #11    This is the continued re-post of the lost original thread.

     I hope everyone has a Happy New Year.    Things are really looking up as far as the new HPA site goes!

     I am finding out what a daunting task it is to re-post my entire old original Beaver thread,  from it's start June 13 2025 to the HPA crash of Nov 26 2025 -  especially changing from six pics per post max,   down to four pics per post max,  and losing the comments that made the thread interesting.

     In talking with George about this,  he recommended to post some of the current latest progress and pics  (Nov 26 2025 onwards to the present),   and post some of the lost old thread,  at the same time,  as I go,  and try not get mixed up.

     Well,  .... I have to split them up -  the current re-post (this one I am typing) of the old lost Beaver thread will some take time,  and will go from its inception June 13 2025,  up to and eventually stopping at Nov 26 2025.

     In the meantime,   I have a lot of posts and pics and text ready,  from Nov 26 to the present day,   of the continuing final stages of the build,  that I have not posted yet.   I will start these posts on a separate 2nd
no 2 Beaver thread,  so I don't get anything mixed up.

   I will use the following Subject title as number 2:
"BEAVER DH C2   no 2   30 INCH RUBBER PARK FLYER DUMAS KIT 306   Nov 25 2025 to Present"

The no 1  is the original re-post topic I am in right now:
"BEAVER DH C2   30 INCH RUBBER POWERED  FREE FLIGHT PARK FLYER   DUMAS KIT 306"

That is the plan ....   here goes ....

     Hi Bjrn.    Thanks for the link to the Beaver pictures.   Hi Bjrn - I lost you link in the crash.   Feel free to post it back in if you want.

     Hi Dput Dave.    I don't think I will put floats on it,  just because I will fly it in the park's Cricket Field.   But I just might put wheelpants on it.    I have a big sheet of  1/8"  balsa that I could use to make wheelpants parts from,  the same size of the wheelpants of my best flying model,  that I beat to death with many Flight reports and repairs -   my Dumas 30 inch Rearwin Speedster, which is now out of commission,  and all my Speedster Flight reports and detailed repairs are now gone into the ether with the recent HPA site crash -  I can just trace out the wheelpant parts from the Speedster plan,  and they should fit.   I got a 42 sec flight from that Speedster.

     I am also looking for a sheet of  1/2" x 4 ft x 8 ft of Homasote Board  (34 pounds) of fire resistant pressed fibre board,  of unfaced cellulose with sound barrier board insulation.   It used to be called 'Beaver Board' in the olden days,  and was used for bulletin boards,  and modellers boards, because it takes round head pins readily.   I have to watch out for warps.   Apparently  they are not sold in Canada any more,  according to Home Depot.   There is plenty to do in the meantime,   including a mandatory trip to Staples to make a copy of the two kit plan pages.

    With the final Hip Pocket Aeronautics modeling web site "crash" of Nov 26 2025,  I regrettably lost the comments and pics of fellow modeller  JOE H.    He had great pics and stories for this Beaver build,  about Alaska and Beavers and fishing and hunting  -  a real outdoorsman before cellphones.

Bruce Feaver,  Shoeless Bruce,  Sundance12,  Bruce/Ratz,  would you please email  JOE H  and send him a link to this new HIP site we are on right now,  to help him get here?  Thank you.

    JOE H  also had a  24"  Guillow's Beaver model that he was flying without landing gear.  He started a thread where he was putting actual floats on it.  I hope Joe show back up.    I thought I had his pics save somewhere -  I can only find his Beaver pic,  so far ...

Pic #1    JOE H's  24"  Guillow's Beaver

    Well,  I looked out at the balcony porch at  3:20 pm.  It was  24 Deg F (feels like 17 deg F) or  -5 deg C (feels like  -9 deg C).    Was that deep dish plate of water ever crowded!  There was four or five in there splashing around in the fresh, not frozen, water,  like mad -  never saw that many before  -  the House sparrows -  all of them all together,  having a good time!

Pic #2    0833  Sparrows
Pic #3    0834  Sparrows
Pic #4    How about these wheelpants

My response to Joe was :
    Joe ....  - Beaver flights into a LOT of remote lakes ?    Wow,  that is the life ...  I only had three Beaver flights in and out,  guiding for fishing out of the small town of Sioux Lookout in North Western Ontario,  in the early 1980's.    That was guiding on the massive Lac Seul  (Lake Seul),  on its Eastern side,  from south to north and back  to the south - day trips.    The first of the fly-in outpost camp locations was way up to the North starting at  Wapesi Bay on the North East end of Lac Seul from starting from the south of Lac Seul,  leaving Sioux Lookout.    The fishing was so great on those fly-in trips!

    We also fished all the way up the East side of Lac Seul from starting at Sioux Lookout in the South.  There was a MNR Ministry of Natural Resources "Portage Man"  with a boat and trailer,  to pull lots of boats out of the water for free, and trailer them around the Pelican Rapids, right away upon leaving Sioux Lookout,  and then we were on Lac Seul spreading North!  We were using 20 horse power Mercury outboard engines.    We would even go (not all the time though),  all the way up to Wapesi Bay from Sioux Lookout using these 20 hp engines -  but, ...  it would take three hours one way,  smacking the waves,  and another three hours back,  smacking the waves,  so there is an idea of how far up Wapesi Bay is from Sioux Lookout.  Definitely need a seat cushion!

      I also had a handwritten map of major landmarks on the water all the way up.  I kept this under the top inside of my hat,  and I would take my hat off and look at it for a second and put it back on -  my clients never knew the difference !    Haw Haw Haw ...  it is easy to get lost navigating all the islands and channels and bays and shorelines !

     Hi Joe,  you lucky guy!   That collage pic says it all.   You must have had a memorable flight or two,  when flying that much,  of an interesting anecdote of a bush plane story.   So sure,  whenever you want,  give us a good Beaver flight story.   I would not mind reading one here.    A little diversion from a strict build,  won't hurt anybody.

     Hi msc Mike.   That  2' x 4'  drop ceiling tile sounds perfect.   Thanks so much for the tip.   In order to build a one piece through wing for the 30" Beaver,  I need a long piece of tile a bit longer than 30" to build it straight and flat,  and I have 39" up the side of my building table,  and I was going to cut a 4' x 8' sheet into four  2' x 4' pieces anyway.    I will definitely check out the tiles from USG Ceilings,  in styles of  "Fifth Avenue 280",   and  "Radar Basic R2310",  on the web before I go buy them.    One less thing to worry about for now.   The price is right!   I will bring a round head pin.

     There are still a few things to get done before I dive back into the build.
-   buy an new "used" camera -  HP 315 Photo-smart Digital Camera 2.1 MP with 32 MB Memory Card -  they are old,  but they are out there on Ebay  see Pic #1 ,   the one that I have always used for this hobby
-   buy some Ceiling Tile as per msc Mike
-   take good pics of my two kit plans,  so everyone can see the model features
-   photocopy the instructions etc.,  weigh the individual laser cut balsa sheets of parts,  and calculate the weight of the balsa
-   clean off and prepare my building board (not a small task)
-   start cutting out and labelling parts

     And here is a very short 33 sec video of a float Beaver fly by,   and the sound of the Wasp engine

    Hi Joe -  great fly-in fishing story!  Not too long at all.    The myth of the Bush Pilots lives on.    Those pilots must have developed a real  "feel"  for a sluggish take off run with an over loaded float plane,  and smart enough to abort the take off,  with enough lake water left to do so,  before hitting the shoreline.  It got me wondering just how much space in the float is used in the floats, for the load,  and how many pounds one fully loaded float can carry ....  Thanks for the pics too.  It looks like you guys had such a great time!    Just barely missing the tree tops on takeoff climbout !?! ....

     This should be a straight forward build.   There is only a one piece wire for the landing gear,  which means no soldering.
     There are two large plan sheets needed,  but Dumas printed them on both sides of one sheet -  separate sheets are needed for my liking.
     There are  80 laser cut parts on three sheets that are slightly thicker than  1/16"  and  3" x  17 31/32" (almost 18").

Sheet A  =  11.70 grams      equals  12.0  lbs/cubic feet
Sheet B  =  11.31 grams      equals  11.58 lbs/cubic feet
Sheet c  =  12.80 grams      equals  13.1 lbs/cubic feet

Strength for the hard landings?    We will see if it still flies,  with these onerous weights.

Pic #1     6648     large plan sheet no 1
Pic #2     6649     large plan sheet no 2
Pic #3     6651     Kit contents
Pic #4     6653     three laser cut balsa sheets   =  80 parts

For comparison,  there are 250 laser cut parts for the Dumas  30 inch  Gipsy Moth Biplane.

It should be a snap to cut these laser parts out.

CUTTING OUT THE LASER CUT PARTS    17 pics

     Well,  I just finished cutting out,  final sanding,  and labeling of all of the heavy balsa parts,  as good as I could.   This was another ordeal.   Even though the kit was laser cut,  those small balsa bridges were difficult to cut through with the exacto knife.    It was even more difficult to sand those balsa bridges flush to the  'kerf'  of the laser cut.

     Before I started cutting out the parts,  there was one slightly damaged (damaged enough !) rib.   It had a straight vertical shear (strange?) ,  right through the rear of Rib 1,   3/4 distance from the front of the rib,  that rib being  located on the lower left corner of Parts Sheet 'C'.    These ribs have deep under camber (or so I thought),   but are really hollowed out ribs -  see Pic #17   IM006686   TYPICAL SECTION AT RIB  snip   diagram of Typical Section of Rib.

     I white glued it all up where it sat,  with pins and strips of waxed paper and small balsa planks,  and let it dry overnight  -  it came out OK !   Better than cutting it out first,  because of the rib shape -  "small things ..."

     I haven't read through the instructions yet or read the plans completely.   Here are some notable features so far.

1     constant wing chord
2     unique wing rib construction
3     the stab is enlarged from the original scale outline (which is also shown on the plan).   Dumas does this to make the model fly better.

     I have been making a lot of   8 1/2" x 11"  photocopies of the plan sections to work on,  and reading up on all of the instructions.   

     There are some changes to consider,  as I was going with the Kit Box Art,  for the color scheme.

     This is not a super scale model.   There will be no three blade scale flying prop.   Also the stab is enlarged to  12 1/2"  from a  10" length.   

     The kit prop is not the  9"  black square tipped plastic prop on the kit box.   It is now a  9 7/16"  white plastic rounded tip prop.    A new color scheme is now needed,  no rush.   And a Beaver logo to chose from.

     It is just a fun park flyer (no floats),  so I am still considering something instead of just bare wheels.    I still can't find a pic of a Beaver with wheel pants -- maybe nobody ever put wheel pants on a real Beaver,  even just for fun.

     Here are a couple of ideas ...

Pic #1     Is this a Beaver with wheel pants -  it looks like metal car fenders.   Maybe those fenders were early mining airstrip wheel pants,  you know ... ,  for blocking the fine stones from hitting the bottom of the fuselage ?   Or maybe not ...     I need a round steel mandrel so I can hammer out some thin metal fenders  ...

Pic #2     Vintage Wheel Pants

Pic #3     THIS BEAVER HAS WHEEL PANTS SPATS  not a beaver LOL

Pic #4     Beaver with Wheelpants or No  --  solid wood model    wood radial engine   wood cowl blisters

Sorry for any double posts of pics

COWLING ASSEMBLY

Pic #1     6714     I  'invisible tape' taped,  a paper photocopy of the plan's "rear cowl ring pattern",   to the 0.020" x  3" x 10" white plastic sheet.   Before I do cut it out,   I did extend all the lines,  with a clear 6" scale, and a French curve,   out past all of the ring part outlines, out to the edges of the three by ten plastic.   I may later on need this carefully cut out 'template',  thusly created ...  That is,  to help make that dotted cowl reference line,  easier to locate later.

Pic #2     6716     Here I meticulously cut out the four  1/4" sq balsa frame supports,  and sanded them.   A nice tight fit of the noseblock is everything ...  Ever hear the flying 'rattle' of a loose noseblock?

Pic #3     6718     Here I white glued the two  1/16"  halves of the cowl firewall together,  and hoped for the best.   I also started gluing up those four supports,  into a square. 

     I did a glue experiment with white glue to see if any of it would stick,   using plastic and balsa combinations,  and clamped them off with clothespins.
 
Pic #4     6721     Well,  it took three glue applications to properly white glue those  1/4" sq  supports.    The butt ends really suck in a lot of glue.   All nicely squared up now.

Pic #1    6723     Glue experiment  -  nothing worked

Pic #2     6726     I got up at 5 AM and took apart the dried square balsa frame support.    No pic - just a quick sand on a flat piece of sandpaper,  and I glued it up on the E1A/E1B firewall.

Pic #3     6728     The firewall with the support square is done.   The black thrust bearing is  0.300"  diameter -  the hole for it is now cut out of the plastic cowl.    The rear cowl ring is now cut out also.

Pic #4     6732     Here is the white kit prop  9 7/16",  and a  prop wire hook of   0.040" which is quite wiggly in this prop.    A wire of  0.046"  ( 3/64")  #54   is less wiggly than 0 .040,  and this  #54 drill bit is the max diameter of wire to fit into that white plastic prop.    The hole in that white prop is  0.053" #54  max.    I need an new  3/16"  prop wire,  and a smaller prop with a matching smaller hole.

Pic #1     6734     The kit supplies a Wasp radial engine outline on the stiff paper pattern sheet -  0.0085" thick -    that sheet also has outlines for the doos, windows, and wing fairing.   I started working on a color scheme.

     I'll  try some  5 min  epoxy tomorrow,  and glue that small tab on the rear cowl ring,  into the big ring to fit into the plastic cowl.    The white glue experiment did not work at all.    I will try some,  thinned with acetone,  5 min epoxy,  tomorrow.

Hi ZK AUD Mike!   Thanks for the comment.   I will take your advise on the CA glue.   I did stock up a while back on CA  glue and thinner from Windsor Hobbies.  see   6747 .     My medium 'gap-filling'  CA will give me 5 to 10 seconds to dry,  to move parts into place.

     I finished the engine color scheme,  and I am just building up the whole plane color scheme as I go now,  but I have the engine color scheme finalized in good and waiting to be cut out,  and an already cut out,  previous colored engine version,  is sitting in the engine now,  just to see how it looks.    The color scheme is finalized and shown in Pic #4   6742    .

   I also painted up the thrust button and the forward crankcase of the engine,  with three coats of  "Silver Morning"  acrylic.    I found a good gray plastic prop  7 7/8"  with rounded tips,  and my last four prop hooks of  0.046" diameter wire of  3/64".     And two prop wire washers or a bead - to come later.

Pic #1     6742     The good colored engine ring is finished on printer paper,  and the older version is sitting in its spot on the plastic Cowl.
--------------------------------------
The key for the six-color scheme on the engine ring,  is as follows:

Two Studio "Staedtler" fine line felt tip markers were used ...
1  light blue  for pushrods and pushrod nuts at the case
2  med gray  for upper pushrod nuts and spark plugs

One crayon was used
3   a slightly darker blue,  of Studio 12 Color Pencils/Crayons,  for shading in the cylinders

Pencils were used to shade the background and engine casing
4   light pencil gray for shading the background
5   light pencil darker gray for engine casing and spark plug wire harness

One fine line black gel marker was used
6   Studio black gel marker  0.5  mm thick,    for spark plug wire and wire harness ring

Pic #1     6765     The  20 thou thick,  white plastic Rear Cowl Ring,  is bent around in a circle,  to get glued.   The top of that tab is CA glued to the bottom of the other end (outlined),  of that cowl ring.    It is very springy and difficult to glue while you use pressure to hold that little tab in place,  for 5 to 10 seconds -  I practiced the motions and finger positions several times before actually gluing ...   I actually had to try gluing this three times to get the correct cone shape angle, and cone flare ... for everything to fit.

     There is only one piece of that 20 thou thick white plastic sheet in the kit.   Game over and thread kill,   insert emoji here  if you don't have any extra sheets of that plastic,  and you make an incorrectly glued up Cowl Ring,   and there is no more ... 

     Luckily, ....  The gods of free flight were shining down brightly,  being that I  already have two big sheets of two feet by one foot,  of that  0.020" thick white plastic,  that have been sitting around for years ...   It really saved me, considering that I had to cut out and glue up, (comma, breathe), three rings before getting it right.   Scowl ...  Insert emoji here  BEWARE fellow modelers.   Stunk up the bathroom for 2 days,  slow fan,  and I was extremely quick and lucky on the third time,  believe me,  and I never got any CA on me at all which was a wonderful experience,  in and of itself.

Cowling

     Here is the Crux of the situation.   That flat plate of the nose plug that has the square walled nose plug built up,  the edge of that flat plate (E1 assembly of E1A and E1B),  that flat plate must be glued,  by its round edges only,  to the inside of,  and flush with,  the back flared edge of the Rear Cowl Ring.    NOT an easy task.   Insert mad emoji here

     The rear Cowl Ring is the shape of a sliced section of a cone shape,  such that,  one open end is slightly larger than the other open end.

     So,  the front opening of that rear cowl ring must be small enough to slip into the rear of the Front Vac Formed Cowling,  but large enough at the flared larger opening to accept the E1 balsa plate assembly edge.   

     The square male end of the removable nose block that is glued to the firewall plate,  that square noseblock,  seats and locates,  into the square female hole of the forward fuse plate former.    Mortise and Tenon joint.

Pic #1     6773     The stiff paper engine outline 8.5 thou thick,  is cut out free hand very incrementally,  on a fresh new cutting board,  and sanded inside and out.

Pic #2     6775     Ready to stack the black tracing first then the colored engine on top.

Pic #3     6777     There is still a little flare of plastic sitting proud on the  vac-formed  Cowl,  yet to be sanded.

Pic #1     6789     The tiny plastic burr at the rear of the vac formed Cowl,  has now been sanded away to a smooth transition.

Pic #2     6793     The rear Cowl Ring has to go in to the proper depth dotted line.    This tricky procedure will be done later with Medium CA gap filling 5 to 10 seconds to dry to allow for adjustment time before drying ...

Pic #3     6795     Vac-formed Cowl and Rear Cowl Ring final fit of front view of the plan.

     My third try of that Rear Cowl Ring, was just fine in order for it to slip into the front cowl,  but a smidgeon too small of the larger flared opening,   to accept the  1/16" balsa plate E1 assembly.   But it was so close it was OK.   I just sanded in the bevel edge angle ,  from the flare angle,  into the edge of the E1 assembly,  which brought it so very close.  Then,  I sanded incrementally all aound the edge keeping the same bevelled angle,  and I finally got a super tight fit !  It should be pretty close when I match it up with the front fuse former(s).

    I will edge glue this all up later,  too.   

And that's my story.
