RE: Hacker x AXI x E-flite in a Divo
I'd go with the Hacker A20, I'm always impressed with these motors. They very rarely get hot as long as you use the recommended prop and they're very efficient which gives you good flight times. Pair it with any 18A ESC and you'll have yourself a great plane.
I've had a Hacker A20, A30 16M and A30 10 XL and they've all been excellent.
