B-29
I am curious about the retracts. Who are the manufactured by? I noticed later in the thread that you mentioned some modifications to the Robart nose gear. Are the mains by someone else and the nose by Robart? Also curious about he wheels and if Dwayne installs brakes on the plane?
Thanks

Sorry about the delay
I haven't been tracking the thread very carefully since the maiden
Dwayne says his big (1/10) bomber has Century Jet gear that he modified to improve durability and strength, mounted with Robart wheels and brakes on the mains by a local machinist
The smaller one (this thread) is Robart gear and wheels and brakes all around. Cheap wheels you see here were just to template the build

B-29
Four cowl assemblies almost ready to go
I try to create them all identical, tracing them off a single pattern, but note that each part is labeled with its engine numbes, so that tiny little tweaks can be made to each assembly for a perfect fit
Making four of each thing, "assembly line" fashion really shortens manufacture and assemble time
Aluminum engine mounts are a must.
Period
Also do you know someone else in your group of friends that has a project B-29 that they have tired of?
Thanks

Just beginning my build of the 169” B-29
You must be looking through a limited device or web portal.
This thread is quite long: as close as I could make it to an Illustrated Build Manual, start to finish
Dwayne has a dozen or so additional flights on the bird now and it still looks good. I consider the thread to be complete, although comments and questions are welcome
Sounds like you're on your way
Hope it helps

The two 169”s I am familiar with belong to Dwayne and Frank. Built in about the same time frame, they each have several seasons of flight on them and both pilots are the elite of the bomber community.
Dwayne put Saito 125’s in his, the same engines I have in my Wingspan 138” B-17. They run great and sound great and turn 3B MAS 15x7’s about 8,000. Dwayne, who is accustomed to overpowered bombers, mildly *****es about “it’s too scale,” meaning he can’t yank it around. He thinks OS 120’s would be better
Frank’s has DLE-20’s turning 3B MAS 15x8’s about 7,000 and he never complains about available power, but that may just be a stylistic difference
i LOVE my Saito 125’s, and it seems to me the gas engines, although much cheaper to fuel, require a lot more tweaking to get just right. Frank is a gas engine “whisperer,” and it took him a while to get all 4 where he wanted them. Not sure the average bloke (me) could’ve done that
hope this helps

Wing sheeting 1/16” VS 3/32”
In my parts kit it comes with 1/16” wing sheeting. It's commonly used on 6-8’ span wings does Dwane use 1/16” on his builds. It just seems to me that 3/32” would have a better compression strength which is the cause of wing failure. The bottom could be 1/16” because its got more than enough tensile strength but that would change the airfoil flatter on the bottom slightly. I’d really like your opion on this
Thanks

Lol. Oh man I was looking at the wrong bundle of wood. I think I’ve answered this myself. They supplied 3/32” x 48” for the inner wing section. Wow. To many late nights prepping. I try to use the “measure twice and cut once” Philosophy when it comes to this. I’ve never built a aircraft this big before. They are in their own League
