Default G4 Nitro Head Speed

Just wandering what head speeds you guys are using with the stock gear ratio? It really seems more suited to F3C flying.

Thanks

Tim

Powered by a YS 120. With head speed of 1700 I get 9 minutes of air time.

YS91SR

1650
1900

My G4 flies awesome at 1650. 1900 is great too. I wouldn't spin it too much faster. This seems to be the sweet spot. I'm running 14.5 pitch, 11deg cyc.

Hi

I run 1850 and 2100.

Always fly in idle 2, but only 11 deg pitch. 6++ minutes flights.
