Well, A50-16L on 10S is rated for 16x10 and we all know how much Hacker is conservative. It would be able to run day and night on 16x10 so for pattern style type of flying also a 17x10 would be OK. Motocalc shows very low excess of trust from the optimal cruising speed for 17x8 but that should be tested. If 17x8 proves to be enough than it is also absolutely in line with how much this motor can take and braking effect would be great! If my 4035 fails I might try A50-16L.</p>

And are you all using low timing on the ESC?</p>
