Eflite power-19's for the motors, a pair of 1.20 sized 85 degree electric retracts for the mains.

Can't find 19's , when I ran a calculator it showed that I could run park 480's on a (4) 3 cell 2200 should get about 6 minutes flight. Why did you decide to go with the size you are using? Just hoping I did not miss something

my bad, power-15s.

park 480's seem small for a plane that is going to be in the 12-15lb range.

The Royal B-17 was originally designed to run on 4 Veco .19 nitro engines... ( this is where my power-19 thought came from ) ...

E-flite power-15s are meant to be a drop in replacement for a .15 sized engine, so they should be roughly equivalent to the original spec of a .19 sized nitro

Cant wait to hear how she flys. Where did you find 50cal guns that fit. Having a struggle finding any add ons. Also what is your distance between the engine mount rails mine is under 35mm

Tamiya Sherman Tanks: part number 9225067
You can just order the .50 caliber gun in 1/16th scale

I cut the engine mounts off and mounted the motors to the firewall....

We're the old aluminum cowls cut for glow engines? I'd like to buy them for my plane. Cut or not.

They are cut and drilled for mounting ... I'm not really sure what they are worth?

Learning exercises are not used in the real world of full-size airplanes. After 30 years in storage, your dads beautiful 17 deserves to be out=fitted from the start with the RIGHT STUFF. Do not skimp here. I know this is an old post I am writing to. I can't wait to see how the end turns out. Great job!

I've got one 4 built royal b17s, they use 90 degree nose wheel retracts and I'm not sure what size wheels.
