i wanted to ask if 3 in 1 oil is ok, i do have wd40 but dunno which is better. also, i have a question about changing the main motor, i still dont get why i shoudl change to 9T though. one thing is that it'll burn out my main faster with a 10T, but i'm never going back to the ni-hm batt so i'll have no use for the 10T anyway. so i just thought that a 10T would gimme faster head speed and if i burn it out, i can just put the 9T on. please explain.
3-in-1 oil (just a drop) is better because it won't break down as fast, only offered the WD40 as an alternative. Also the lower tooth pinion is to protect the tail motor, not the main. The main is a pretty strong motor, but at higher amp output you'll fry the tail trying to keep up. I use the 8t pinion and have no problems with agility even at the lower rpm (and have yet to lose a tail motor after 10 months). But then again I also upgrded to the GWS 50 motor before I ever flew it. Too bad about your 4-in-1, bet you don't do that again
