I will be building this for a friend who lives a good distance away, so instead of sending pics to him directly I fighured I'd make them public for all interested. It will be p60 powered, Y/A retracts, robostruts BVM wheels and brakes. Here we go.

Tanks assembled, servo hatches cut out, servo hatch mounting blocks attached, wing spar reinforcing plates glued to spars, spar slot liners glued in wings ( not yet in pics ), nose gear mount assembled, speed brake hinges glued to brake. We'll maiden it on your B Day for sure, hopefully, well... Maybe.

Hello,
nice work so far, i have just finished one off but for an edf.My last one had a homebuilt Wren 54 on it and was overweight and overpowered a p60 will be more than enough but i think a p20 would work???,
cheers Euan.

The Wren44, the gold, or the P60 are supposed to be good choices. For this one, we have a P60 ready. Goals are for a slick airframe with with emphasis on build quality and light weight. We are keeping the P60 propane start. Hope to have her in the air in July.

Hi,
Nope, not a high-speed stall based on what you wrote. Sounds like radio to me, but a stall is going to require some AOA on the wing, and if it's just smoking along straight and stops responding (not in some pitch-input situation), it doesn't sound like a stall.
