My own fault. I took the baffle out of the muffler to increase power, well it also reduced the backpressure, so I had to run the bottom end a bit ritcher to run and standing it up in a hover, it died, twice.

It cost me two planes to figure it out and it was my own doing. It's just dead to me.

160 is a rocking motor and have zero problem owning one, except for the one I own now

I grew up flying 3D on a 2 stroke motor so I have no problem doing it, however after flying the same plane (not this one) back to back with different motors, I like the strokers for 3D stuff better. Really want to do electric. Its that thousand dollar battery pack that hurts.
