Flight Report #4       Monday morning of April 6 2026

Pic #1     2254     second flight,  45 winds,  soft forward flip on soft landing,   perfect flight slightly right.   

Pic #2     2255     This pic shows the right thrust shim,  and the down thrust shim on top.

Pic #3     2256     60 winds   launched at too high of an angle,  and it climbed out and made a soft flip landing.   I think I lost the  right thrust balsa shim on this landing ...

Pic #4     2257     Time to quit as the wind was increasing and veering and spending more time near the max gust mph.     The long new growth,  willow hanging branch twigs,  are yellow,  and the long slender buds were half yellow  yesterday,  the buds now turning into leaves and aments or catkins.

Flight Report #4       Monday morning of April 6 2026

Pic #1     2263     We have about three big colonies of squirrels here.

Exiting Jackson Park from where we came in.

Pic #2     2264     On the way out.   The wind has increased on the flag.

Pic #3     2266     A ton of cones have already fallen out of these two Dawn Redwoods,  almost carpeting the ground and main paved trail.

   I need to practice stretch winding using the field winding stooge.   Maybe another bench test motor run or two for practice,   and make a few more shims,  and definitely bring spare elastics for the Landing Gear Fairings tie-downs (in case they break).   Then I will try longer flights,  stretch wound in the stooge.   I am going for ten second,  hopefully circular,  flights,  but flying anywhere with-in the Cricket Field is good.

     It is a good thing I got these flights in early in the morning,  as it rained off and on all day.

     Time to do a real maiden flight -  using stretch wound rubber motors from a winding stooge .

Hi Richard

Great progress.

If the slackening of the tissue bugs you (it would get to me) - Doping the tissue with old fashioned cellulose dope or with banana oil will make the tissue more resistant to damp and reduce the amount of slackening when the air or the ground is wet.

You can get non-shrinking dope, or use banana oil (also called Isoamyl acetate), if you are worried about over-shrinking the tissue.  If you're allergic to dope fumes or dislike the banana smell of banana oil, you could try Eze-dope, which is water-based, but try it on a test frame covered with Silkspan before trying it on the model.

     Hi Jeremy.   Thanks for the input.   Yeah,  this Beaver is not going to be a pristine "Hangar Queen" -  it is relegated to a life of active,  remote mining exploration flying,  on gravel runways,   until it can't be repaired anymore.    There are a lot of mistakes -  wrinkles etc,  I already broke the wing off ... ,  but that is OK,   as I am using the Beaver as a  'park beater'.

    I just want to have some fun learning and experimenting with flying,  crashing, fixing up,  and flying again ....   The object is to get trimmed out circular flights,  within the Cricket field,  of ten seconds,  with stretch wound rubber motors ..... and to try to get some good,  in-flight pics ...

     I just got in the first four flights yesterday,  using the Winding Stooge,  for stretch wound rubber  (170 stretch winds)  motors in the Beaver.    Details coming up.

Flight Report #5    early afternoon of Tues April 7 2026

On Tues Apr 7 2026    Just before noon,
I suddenly looked outside and there was no wind ...

    I had been working on getting new fresh elastics for the wing tie downs,  and the landing gear fairings elastic and paper clip tie down,  and found some good spares for each.    I will replenish the elastics with fresh 'assorted elastics'  from dollarama.

    I also made up some more balsa shims -  they keep flying out of the nose on landing,  because they are not glued in yet.    I also sanded those two shims in the nose,  for a good match,  giving right thrust and down thrust on the nose.

      So,  seeing there was not a lot of wind,  and Jackson Park is right across the road ...  I then packed up and left at  12:30 PM  with the pack and the winding stooge et al,  and went to Jackson Park for Flight Report #5  Tue Apr 7 2026.    The weather was 33 deg F (feels like 40 deg F),  only 45 % humidity,  winds blowing 8 mph SW, 

      I had just finished Flight Report #4 the day before on Mon Apr 6 2026,  using  up to 90 finger winds and a max flight of 3 seconds.    Today Tues was the first time using the winding stooge and I got in 4 flights -  the best two were each 170 stretch winds for 6 seconds and 4 seconds.    Then the wind was too high and we quit,  with no damage to the Beaver.

Flight Report #5    Tue April 7 2026  post  1  of  5

Flight #1  150 stretch winds  launched too much of an angle down ward,  went straight.

Flight #2    170 winds    six seconds !!  goes up high into the wind very slow then settles down almost straight down,  into a perfect soft three point chopper landing.
Never saw that before.

Flight #3    170 winds    four seconds  the same exact flight as the six second flight above.

Flight #4      170 winds  but the wind caught it for its first light half cartwheel landing  -  no damage.

Pic #1    WIND  FORECAST  TUE APRIL 7 2026 NOON

Pic #2    2271    I was working on new spare balsa shims,  and new spare rubber bands and paper clips,  and two spare 7" motors four strands =  two strands 3/16" & two strands 3/32"

Pic #3    2272    We now have spare rubber bands picked out,  but I will buy new Dollarama "Assorted Rubber Bands".

Pic #4    2275    The Beaver is in the winding stooge.

Flight Report #5    early afternoon of Tues April 7 2026

Got home at 2:30 PM  but went back out at  4:00 PM

     I went home and started making more shims,  as the shims were flying out on landing,  and I could not find them.    And I started replacing all the rubber elastics and pulled out two new  7"  motors.

     I know that I can get  10 to 13 seconds on 250 stretch winds with the  seven inch motor .    I just got 6 seconds on 170  stretch winds ....

Worked on the model.   Then it looked like no wind at 4:30 pm.    38 deg F ( feels like 49 deg F),   winds were good still,   blowing  6 mph from NE gust 9,  and the humidity only  40%.

   Back into the park we went,  at  4:30 PM,  with the Beaver and a full pack loaded for bear,  but the wind seemed to stay mostly at the high end of the gust speed,  blowing  8mph  from SSE gusting to 13 mph.    I did not fly it,  so I took more pics in the park.   So,  I only got those four stretch wound flights in the early afternoon,  Tues April 7 2026 Flight #5.

Pic #1     2276     Perfect three point landing after rising high on launch, going slow into the wind,  and floating almost straight back down, but going a little forward,  to its perfect landing.   It did this for the  6 second flight and the 4 second flight.

Pic #2     2277     Both shims are knocked out on landing.  The second shim is barely visible by the prop blade.

Pic #3     2278     Another view -  you can see the other shim under the nose.

Pic #4     2279     This patch of grass on the West side of the Cricket field is the best in the Park.

     And we finished off with some nice coming alive nature  pics,  with the return of the Sun and the Spring Equinox in Jackson Park.

You are making progress Richard - it won't be long before you achieve your circular flight paths.

Thanks John.

Pic #1     2284     The Beaver stopped in to say hello to his Fox snake, Barn Owl,  two Black squirrels, and bat friends.

Pic #2     2285     This is a nice Sycamore tree budding out in the background.

Pic #3     2286     The big carved flying eagle at the top,  and the red headed woodpecker underneath.

Pic #4     2287     I think these are the  'snowball trees'  or fragrant Vibernum sp.

Flight Report #5    early afternoon of Tues April 7 2026

Pic #1     2288     The shadows are getting longer and the wind is still too strong.    We need  8 mph wind or less.   I think it was gusting to  13 mph.

Pic #2     2289     Last pic.   Too windy.   

     Well I am glad to get some stretch wound flights in with good results so far,  and glad to get home undamaged.   The park has a long way to go before all of the grass turns green and grows thicker.   

     Today Wed April 8 2026  the temp really dropped over night this morning from Tues evening,   to  21  deg F  or  minus 6  deg  C,  first thing in the morning.    And the gusts were way too high,  so no flying today Wed.

     It is time to glue the balsa down-thrust shim,  and the right-thrust shim,   onto the balsa fuse nose,   1/16" thick,  flat round former firewall  plate  1A ,  before the next flying session.   With that offset of the tenon,   comes less tenon depth,   to hold that noseblock tenon in place,  in the fuse hole mortice.    Hence all of the balsa shims and noseblocks popping out,  upon landing.

Making the Big Shims       Fri Apr 10 2026
Before Flight Report #6 on  Sat Apr 11 2026

       I need downthrust and right thrust on the noseblock together,  which produces and double angled plane.   I tried to glue small shims onto the big shim,  to get the desired effect.

Pic #1     2301     The big shims have downthrust only built in.    There are lots of quarter moon shims to work with.

Pic #2     2302     Closeup of the above.

Pic #3     2307     Here we are sizing up two small shims on the big shim at the top.   I broke the no. 2 big shim in the thin corner.

Pic #4     2315     This shows the slight overlap of the two small shims.
