Mini AC & 2 Meter ??

Need help or suggestions concerning powering a 2 meter sailplane.

My main question concerns using a Mini AC 1215/16 with a 6:1 gearbox on a light 2 meter sailplane. I will use 8 cell KAN packs.

Hobby Lobby claims this brushless motor is the size of a "280" with the power of a "480". This is a 1.7 oz. motor.

Anyone tried this motor in a sailplane?

I would like to put this in a Sky Bench Aerotech 2M Lil Bird.

Thanks for any input. jmh

I'm using the miniAC extreme 6:1 (more power, more rpms than the /16) on 2S lithium. it's in a 25oz AUW 1.6m sailplane, climbout is good, 45-60 degrees. I'm planning on trying a 3s setup to get the power up. I like my climbouts vertical

I think a 3s3P pack of etec 1200's, with the extreme 6:1 propped up to 12x8 or so (30+A) is the way to go. or, 8-9 cell 1700aup if you want a cheaper battery pack.

on a 30oz+ airframe, I think the /16 is going to be dissapointing after spending all the money... the gearbox is very noisy, btw.
