I just ordered the 65" Yak from OMP
GREAT flying airplane.
Easy build. Keep it light and straight. Shoot for 7lb AUW.
Saito 100
APC 16X4 wide chord prop
I used the Saito 100 on mine. No regrets.
Fuel with Powermaster 20/20. Use a OS-F plug. Takes 3 gallons to really come in.
Enough power for good pullouts. Not ballistic, but more than adequate.
Settled on the APC 15x6 as day-to-day prop. Your flying style may vary.
Hitec 5925 on ailerons, elevator and rudder
Seems like overkill for a 7lb airplane.
I used 5625s for ailerons and elevator. Plenty of torque. Accurate. Cheaper.
Already had a spare 945 for rudder so used that. Otherwise would have used a 5925.
Hitec HS-81 for throttle
I've had bad luck with flakey servo pots with these servos.
I avoid these like the plage in powered planes now.
Already had a HS-85MG, so I used that.
1600 mah 6V airborne pack
That's what I used.
The servos above draw a ridiculouly small amount of current.
I get about 4 hours of flight time to a charge.
