Why not? Worked great on the Raptor. Oh, wait...
After all the discussion about making a reduced scale ME-262 I got carried away and built another mock-up. Some years ago I built a 70% P-39 and this time I chose 55% as the scale. Starting with a giant scale RC model model plan I made templates of all the cockpit area and using a large shop made planimeter blew them up to 55% of full scale. The construction is a combination of double wall corrugated from Uline Office Supply and some 1/4" plywood. Lots of Gorilla and Titebond glue. The skin is construction cardboard available at Home depot in big rolls.
As it turned out 55% is not really big enough unless you are a smaller person. I just finished the project and actually haven't sat in it yet. I have to get it off the rotisserie supports and on to the cradles before we can do a trial fitting. It will be tight. I think 65% would be a better design point.
I built the Nightfighter version with the two place canopy, but at 55% only a 12 year old could sit in the rear seat.
Here are some photos of the project and I'll post more in the next couple days with some people in it.
Cool..it wasn't big enough even with reclined seating ?
That's really impressive! Nice work.
Very nice, 65% might work for a single seater, between 70 to 75% will be great. Following this thread with great interest.
I like that mock up.
That mockup is awesome. A little larger and you at least got a nice cockpit for DCS world
And I have decided that the BD4 will DEFINITELY be my last built......sigh.....

The trial fitting happened today and it's definitely small. The biggest problem is the width of the canopy sills which are about 2" under sized. If you notice in the photos I am sitting farther down in the seat leaving some head room unused, That;s to get my shoulders under the sills. The length is OK. I had to cut some off the bottom of the panel to get my legs under it.
Fun project, I'll hang it on the hangar ceiling next to the P-39.
The 262B would work as a two place homebuilt at 65% with an additional 2 inches added to the cockpit width and an inch to the height. No one would ever notice the slight scale departure and that would allow more comfortable seats and elbow room. The seats in the 55% one recline at 35 degrees much like a high performance glider. I measured the seats in a Longeasy and they are 45 degrees.
If a single place would suffice a 60% version would work wellwith the additional stretches mentioned above.
The next project to ponder is a large ducted fan, something in the 15-17 inch diameter range. There are some large EDFs, up to 250 mm diameter, on the market from Vasy and Schubler that produce up to 125 lbs of thrust. A 15 inch fan could produce up to twice that thrust. The difficulty, once you have an EDF, is how to power it.
Dude you read my mind.
