Default scorpin 1400

What head speed can I except see running a 14 tooth pinon at 100% throttle using a scorpin 90 amp controller?

If you are talking about the Scorpion 3026 1400kV motor, then with a 14t pinion it would be in the 2400rpm range, but with this motor you should run a 15t pinion (2550rpm HS) and hang on as this is a ballistic combo on the 500...........

I just bought that motor with the 15 tooth pinion. I look forward to my first test flight.
