Can anyone tell me the max operating temp for a o.s. 21vg i just got my revo and i'm in iraq so i can't go down to the LHS to ask for info? New to RC so any help is appreciated
Most nitros run best anywhere between 230 and 270 degrees. I'm not sure about that particular mill but if you keep it in that range and allways put your piston at bdc when done, you'll be fine.
