My friend has this plane and it weighs in at 15 pounds. Here is his setup

OS 160 FX with Bisson pitts muffler.
Hitec digital servos. 1 on each aileron, 1 rudder, and 1 elevator. Pull-pull on rudder and elevators.
TME smoke pump with 12 ounce smoke tank and 600mah battery for smoke pump.
1650mah 6 volt receiver battery.
30% lifelike pilot figure.
Mejzlik 18X8 prop.
CG set at 5" behind leading edge of wing. the manual says 6" behind leading edge but was WAY to far back.

Plane flies great!!!
