Hi Papa! Welcome to this forum,

That 1940/6 a rather hot motor (it will take serious amps on 16 cells) but with the right gearing and perhaps a fan on the 9920, it would be fine.

It would be a blast on 16 cells for sure.

I you are planning on on running 16 cells all the time, i would get the 1940/7

What is the reason you choose a 1940 over a feigao motor?

the feigao 7XL is also a very good choice for 14-16 cells. (even 18 works like a charm (rocket allert))
