Inconsistency. I tried running the governor on a couple of my Trex
helis and the HS would vary up to 400 RPM. I've had more consistent
headspeed with liberal use of the Eagletree logger and some trial and
error with pitch and throttle curves.

RevCo has an entire line of pinions with the proper shaft size and
modulus. MUCH stronger than the pinions that normally come in the
kits

Any particular reason you "detest" the forums?? Some of 'em are full
of knuckleheads who like nothing more than berate everyone else..
Some are dedicated to the advancement and sup****t of the hobby. Most
have useful info tho.

Running the 12T pinion?

My Trex 600s will hover pretty good at about 50% throttle and 9
degrees of pitch. HS is a tick under 1400 like that. Cyclic gets a
little mushy, but they'll hover out of ground effect quite easily. I
normally run the head about 2000 RPM on these helis and get 6:30 out
of a 5000mah pack.
I haven't tried it with a 450 or a 500 yet tho.
