View Full Version : head speed

05-27-2010, 05:00 PM
Just wondering what is a good/comfortable head speed on a stock 600esp w/a 14 tooth pinion? I'm at 1900 now and seems ok, just looking for a sweet spot to set my CC 100A to. No 3-D, just sport flying w/a few loops and flips.

Personally I run around 2100 un-governed because I had trouble with wagging and bobbing at lower speeds, but it's a bit loud. I think I'd prefer a lower speed if I could.
There are a couple of guys at my club that run Castle controllers governed at 1800.
Their helis are nice and quiet, very smooth flying.

Its really nice at 1900, smooth, fast, silent, I'll just leave it then.

Are you using the 14 tooth pinion?

I'm using 15T at around 2010 RPMs Governed. It's about 90% performance with plenty of room for the governor
