Andy Borgogna built this model as a test bed for small electric systems. It uses the Baby Flite Streak airfoil, but two extra rib bays. I added the flaps and replaced the horizontal stab with a much larger one. Wing area is about 165 sq.in. The model flies great!
Current equipment is a Hacker A20-34 motor swinging a 6 x 5.5 APC prop at 12,500 rpm, an 850, 3S pack, a KR timer and 20 Amp speed control. It flies fine on 42' of Powerline (Spectra). The size and weight of the equipment are aimed at much smaller aircraft than the stuff Andy uses on his Baby Pathfinder.
I would suggest this as an excellent combo for planes between 150 and 190 sq.in. such as the Sky Sport from RSM and the Baby Flite Streak, Baby Clown and Baby Lightning Streak from Brodak.
