The [link=http://www.amax-toys.com/tem/product_e_16.html] GH-83 [/link] sounds like a nitro if you watch the video, I find it hard to believe it's a gasoline motor. Looking at their website some adds have
gasoline and some have gas powered and some have nitro, personally I think it's just the way they word it, they probably have a bunch of different people that work on their website and everyone words it different.
(i still dont know what a 15a is
It's the size of the motor.
