I've read pages upon pages about why the Align ESC governor mode is worthless, useless, teh SuXXorZ, etc., but I had to try it. 35G ESC, 430L, 11T, TP 2200/25C.

Tached 2800/0º, set a flat curve at that point (83%) and gave it a shot.

Why does everybody hate it so much? For my current flying style - circles, 8's, FFF, piro'ing FF, puchouts - it seems to work fine. Judging from the motor sound, it holds RPM better than my curves did. I did get it to bog on a full collective punch from a through-the-wash descent, but that's all. The motor and ESC even seemed cooler than usual afterwards.

Is it really only detrimental to more aggressive, aerobatic stuff, or was I just lucky? I've only done the one flight in gov. so far.

How old is your 35G? I have read somewhere that Align altered the gov program on the newer ESC's.

Most people dont run it because is hunts and surges the power to the motor causing gyro/tail issues.

The problems I've gotten when using the Align ESC's gov mode is that it hunts and surges, causing tail wag no matter how I adjusted the gyro gain. I've seen this with two Align ESCs; the BL35X, and 35G. This was using a 12T pinion though. I just recently tried gov mode again on a 35L ESC with an 11T pinion, and 430L motor (3550 Kv), and it seemed to work fine. So maybe the Align ESC's gov mode just doesn't handle higher load setups correctly. That may be why it works well for you.

I just got the SA combo a little over a month ago. The LHS I got it from sells out of them pretty regularly, so I'm reasonably sure it's a newer one.

Just the teensiest bit of wag at 85% TX gain, and I didn't notice any surging. If the weather holds, I'll give it a proper test at the ballpark tomorrow.
