16/25/3 SETUP
What would be the best setup for a SKY SCOOTER PRO II with the MEGA 16/25/3 motor.

I have the stock 3:1 gear box and the greatplanes 1.7:1 aluminum gearbox, include them in the setup.

RE: 16/25/3 SETUP
What is your idea of "best?" How do you want the plane to fly? That motor can be used to turn the Scooter into a rocket if you want.
For some ideas on direct drive applications, and the motor's specifications, check out http://www.megamotorsusa.com.
I've been running some numbers at http://brantuas.com/ezcalc/dma.asp, and you can get some pretty nice thrust and speed by just slapping a prop on this little gem. Using 8 Sanyo HF4/5AUP cells and a 7x5 APC prop, you're talking over 2lbs of thrust and a 68MPH top speed. Compare that to the original's 18oz of thrust and 31MPH top speed
Amps are around 20; the motor's max is 30A. Zoom-zoom
If you're going for rocket performance, you might want to yank the wimpy little HS55 servos and replace them with something a little more robust, like HS81s.

RE: 16/25/3 SETUP
Just to give you an idea of what this motor can do, I've got my 16/25/3 hooked up to a MEC Superbox geared 3.33:1 turning a 15X8 prop on 16 X 1800 Hecells pulling 27 amps Power out ~350watts, ~70 mph, ~1.5 thrust to weight, on a 54oz ThreeDee rebuild. This motor is incredible. I'm propping down to a 13X6.5 to relieve some of my adrenaline issues while flying.
