Has anyone realised yet that the Lindbergh flight took place on May 20-21 1927?

Yes, I was thinking of that all through when I watched the movie. I was going to mention it here but I'm too stunned - 100 years?? Impossible!

Every summer I get an urge to Build an NX-211 model - gotta commit next year, surely . . .

The thing that rattled me was when I was given a copy of the June '77 issue of AM, which I'd had new, and realising it nigh on was half a century since I'd read it.

Time flies eh?  Unlike my models. Ho hum.

There may be a Peanut plan available in a few weeks/months time.

As I mentioned, the first flight of the NYP took place on 28 April 1927. And which event is scheduled to take place on 25 April, 2027? Close enough? (Hint, hint....)

[TheLurker]

If I can make mine fly, it will be at Walsall all else being well.

It was always my intention to have it ready for the Indoor Scale Nats as well as the centenary, but I hadn't realised the near match to the maiden flight date.

Anyway... got to have something to new fly now that my planned entry for intermediate, the Chiribiri, is in bits in the bin.

Wouldn't it be nice if there were one or two more there?  Would Mr. Prosper please go to the white courtesy telephone in the foyer. Would Mr. Prosper....

Thanks for the link to the film Stephen - it's an old favourite of mine.
On learning that replica's had been made for the film I came across the following interesting story and flight of a very authentic replica.

Have been busy with other things so all I've managed to do this last week or so is get part way through the motor/nose block. That's OK though, 'cos this was a potential stopper.  Needs the holes for the remaining cylinders reaming out, nose plug fitted and sanding to final shape.

I think it's likely the exhaust stubs will be left off until it's trimmed and they may not even be added if I find that they're too fragile to withstand repeated removal and replacement of the nose block.

[TheLurker]

You'd thought I'd abandoned this hadn't you?  No such luck, just been a bit busy.

The first go at reaming out the cylinder holes didn't work, too fragile, so it was back to the drawing board.  This is better, but (note to self) in future dry fit the cylinder separators first to make sure you get a much more even distribution.  As it is they're not badly off, but some are and it rankles.

It would be easier to make the motor with all disks, sand the taper in and then slice the bottom of the cylinders to fit the slope, but this assembly is likely to get mauled in everyday use and I want the cylinders to stay put. As much as I like my Dumas Ryan M-1 it does get a bit tedious hunting round the floor for cylinders when they get knocked off.

1  Fitting the cylinder separators.
2  Pack the gaps with dowel while sanding.
3  Extract the dowel.
4  High technology tooling.

Got there in the end.

The rocker covers and con-rods will be fitted towards the end of the build to reduce the risk of damage during construction.

Haven't got a clue how I'm going to do deal with the spinner, but that can wait until nearer the end of the build.

Combined weight as seen is a shade under 2.5g of which 1g is the fuselage "box".  As long as the fuselage inc. "box" comes in somewhere close to 2g I think it'll probably be OK. The NYP has a fairly short nose so built in weight up front is not necessarily going to be a bad thing.

1 - Motor/ nose block.  Built in right-thrust and down-thrust are about 2 deg.
2,3 - Nose block plugged in to fuselage box


Tell you something for nothing, the next one is going to have an in-line engine!

On to the easy(ish) bit now. Fuselage &tc.

3-D engine cylinders are hard! Good to see someone working on an engine for a smaller plane. Looks good. 90% done, 90% to go.

We have a fuselage. At last.  Just taped togther for the snaps. The box needs another go over with fine sandpaper before it gets glued to the the rest of the framework.

For those keeping count, the fuselage weight (framework + nose box) is 1.6g.

The motor/nose block in its current state is 1.5g.

This is not going to be an especially light model. Oh well.

Very neat Lurk

Only the easy parts to go It will look very impressive.

It's looking very good, Lurk. I may have missed it, but have you said how you're doing the overall colour? Ie. Sprayed, or with silver tissue? Or maybe some other sneaky method?

I have an ulterior motive for asking, having just got a Curtiss Robin kit on eBay which may well be my next kit scale entry. I'm highly tempted to finish the Robin as Douglas 'Wrong Way' Corrigan's aircraft, which was also silvery grey.
(Corrigan, you probably know, worked on the Ryan NYP, and was consequently inspired by Lindbergh's success to follow his own Atlantic ambitions.)

[TheLurker]

....have you said how you're doing the overall colour? Ie. Sprayed, or with silver tissue? Or maybe some other sneaky method?

I have discussed it, but probably only in e-mail messages with various Trinity bods.  At the moment it is most likely to be a very light grey tissue finish. 

I have some lovely lightweight Ag/Al tissue from Peck/Wind-it-Up that is under consideration, but it may be /too/ shiny, N-X-211 has quite a flat finish.  I also have yet to test it to see how well it shrinks.  My previous results with (VMC's) Ag/Al tissue were, at best, barely adequate. If it shrinks well and is fairly easy to work with I may use it instead of the light grey. Stay tuned in for more ...

A sprayed (rattle-can) finish is almost certainly not going to happen.  I did think about it, but I think this model is too small and keeping the weight down is too important to risk it as my first attempt at a painted finish.

In other news. This evening saw the correction of a minor cock-up in the fuselage, photo another day, likewise the mistake on the plan that gave rise to it and the boiling and setting up of the tail outlines.  Bill & John (Ozpaf) will be pleased to hear that the rudder area has been increased by 8.5% c.f. the α version of the plan.

[TheLurker]

It may surprise you to know that The Lurker Industries Aviation C^o. L^td.(Reg. Office Lechlade-On-Thames) maintains a close working relationship with Melrose Aeronautical Engineers (Sole Prop. Peter Smart. Gent.)

Having been told this you may not be surprised to hear that Mr. Smart requested a pre-release copy of the plan to carry out a test build.  The C^o. was pleased to supply same and to have Trinity's resident Stakhanovite set to. 

Levity to one side.  Peter couldn't get his build to co-operate at Trinity today for various reasons, but there are some very useful data that have come out of his build.

- An easier way to build the fuselage. Peter found the former based approach I've used... challenging. He gave up after 3 goes at it. When (if) I've got mine flying I'll redraw the plan using his box and stringer solution. 

- The confirmation that the tail-plane does indeed need to be bigger.

- A simple and effective way to represent the engine turning on the nose.  Briefly; an Al painted ground and then use a dark Al/Ag pen dotted on to that. I'll get the brand of pen he used next time I e-mail him.  The dots on Peter's are on the large side, but even at that the effect from short arm's length is better than passable.

- The rest of it is fairly buildable, which is reassuring.

Enough natter.  Some snaps.
