rotor head speeds
Remove this ad - become a site supporter!
I'm looking for some good info on what the rotor head speeds should be for a T rex 250 and 450. I have been getting good flite times and proformance with my 250 running about 75%-80% motor speed on a 11.1v 900mah lipo. Should I use a tach? if so what rpms should I be getting. thanks
also, what kv rating and pinion combos work best for these heli's
It's okay Pluto, I'm not a Planet either.
