Isnt a higher headspeed better (as in creating more gyroscopic effect/stability)? Now I don't mean going into insane speeds to where the parts come under undue stress from holding themselves togeher.
I hope I can get the stock pinion off the stock motor so I'll just use that.
The higher headspeed does help stability, but like anything else you can have too much of a good thing. It also makes the cyclic more sensitive. Now if I were an experienced 3D pilot who didn't crash then 3000 RPM might not be too bad, but I'm not. So if those blades hit something then they're hitting it with alot more force which results in more damage. And like you said the added stress on the parts isn't going to be helpful either. It also takes a while for it to spin down so even if I cut throttle before a crash it would still hit pretty hard.
My stock pinion was a little stubborn. Anticipating this I bought a GWS micro heli pinion puller from Helihobby, but they're out of stock right now. It worked really well.
