RE: CMP 160 sized Texan
I've been working steadily on mine. I have a Zenoah G26ei in it.
I'll be ordering the Sierra retracts soon.
I have Ram landing lights, Sullivan smoke system, flaps mod from this thread (taken a few steps further) and I recovered the built-up surfaces with aluminum Monokote.
I had a 1/7 scale P&W radial dummy engine for my TopFlite Corsair. I decided to try it out on the T-6 and it looked pretty good so I used it.
