My flight report

The tail has a lot of power. In fact I recommend the AMMO 12-30-3850 if you’re going to a BL tail motor and maybe even a DD tail if you’re not worried about bending the motor’s shaft in a crash. The 3850 is actually the one I meant to get. I have to pay closer attention when ordering .

The head speed is way up. It’s too high actually. It’s 2880 rpm in a hover and 3000 rpm at full throttle. The thing is a rocket. I’m still using the stock Tx so I don’t have the luxury of Throttle/Pitch curves therefore I can’t optimize my set up. Even if I could optimize the curves I’m nowhere near the skill level to take advantage of 3000 rpm.

I’m also stuck with the OE 14T pinion. I’ve heard it’s a weird pitch. Regardless I haven’t found any other pinions that will work. The run time is down about 3 minutes or so from the brushed motor set-up and I’m not happy about that either. With my pinion problem I’m now looking to go to a 2900Kv motor. I look at it this way since there doesn’t seem to be a direct correlation going from brushed to brushless I look at this first motor as a point of reference plus it was only $15. Anyway I’ll let you know how it goes when I get the new one.
