Hi,

I'm about to outfit my first giant scale airplane (28% Edge 540T), and since I've always been a "Futaba Guy", I'd like to use Futaba servos. The problem is that Futaba doesn't seem to have a lot of selection in high torgue servos, and the ones they do make, don't seem to be readily available (Tower, Servo City, etc.). I have included a list of my requirements, so could someone take a look and make some recommendations? BTW, I prefer digital servos, but analong would also be OK. Also, I'll be using a 6.0V airborne battery.

Elevator - 100 oz/in torque minimum (will use one for each elevator half)
Aileron - 120 oz/in torque minimum (will use one per aileron)
Rudder - 180 oz/in torque minimum (will use one per rudder)

Thanks,

John

My good friend recommended I use 3305s on my H9 Suk (1/3 scale). Just received 9 of them from Tower. They are nicad only and sell for $35 each. He would most likely recommend the JR8411s or the 5050 for your most powerful requirements.
Futaba 3305:
Speed: 0.25 sec/60 degrees at 4.8V
0.20 sec/60 degrees at 6V
Torque: 124 oz/in (8.9 kg/cm) at 6V
99 oz/in (7.1 kg/cm) at 4.8V
