rilopez825, I didn't have a Gov on any of my helis till I got my Trex 600 nitro so all of them over speeded a little but not the Trex 600N.To be 100% honest im really happy I didn't use a gov right away cause it forced me to learn how to setup my throttle curves and it REALLY helped me with learning collective management not having a gov.If I had to start all over again I would run throttle curves before a gov.It helps with both me and others cause if a new guy comes to the club and has no gov,I know how to set it up and run throttle to cyclic mixes now.This is one of the last videos I took where I got the throttle curves down perfect.Don't mind the noise the motors making,brand new OS50 Hyper with not even 2 gallons through it and the rear bearing was pissed .
