While it should run faster then 20 there is no way it should be doing 20 at only 1800 to 2000 rpm . tachs are off or someone has put way to big of props on it .


btw your putting one too many 0s on your rpm numbers :D

I may add at 20 you should be around 3000 rpm or so that's why I ask about the tachs and props . How are you checking speed ?
