RE: Ultrafly Ultimate
Hi,
I don't have one.. yet! But my neighbour has one, and I have flown it about 25 times. His using Hacker A30-28S and gets huge power of it. Since he had so big motor, he had to get a smaller pack. His using TP 1320 3 cell.
Prop is... 9 x 6 APC-e and it works great.
BTW, I'm not a hundred % sure on the hacker motor... I think that's what it is.
