Moment = force X distance

2 pounds at 1 ft = 2 ft-lbs = 1 pound at 2 ft

On the seesaw, 100 lb at 6' = 600 ft-lbs moment = 150 lb at 4'

I have a set of Eflite S75 servos and an Eflite Park 480 from my retired Mini Pulse XT. Would those servos work good with this plane?

I've always been leery of using salvaged servos. Servos are mechanical and eventually wear out.

Just got a G-Force G10 motor from Value Hobby, and mounted it into my Leader. A little higher KV than the Power Up 480 plus motor, and quite a bit more power. I got a bit of work travel now, so I'm not sure when it is going to go up, but before winter sets in, I hope. The 480 plus, is going to move to a Mini Pulse.

I looked up the G10 and it's specced at 140g which is I think a fair bit heavier than the PU 480 Plus.

Did you have to do anything to keep the CG correct?

G10 shows at 95 grams on Value Hobby. Weighed in at 111 grams on my scale. I haven't balanced, yet, but I got enough room for adjustment on the battery. Shouldn't be a problem.
