A good choice would be a norvel 061 (break in well on the glow head) and put a davis
diesel head on it , I had one in a global decathon 8x4 master airscrew plane was made
for a speed 400 , I converted it (big deal motor mount and a microservo on throttle)
Awsome first flight but lost in heavy brush and not found palmetto bushs and lots of
coral snakes.
