RE: PLEASE HELP ON SERVO A.S.A.P
It'll fit, but the first time you hit something it's little plastic gears will explode, that is assuming it has the strength to turn the wheels in the first place!! I think that's the cheapest servo I have EVER seen in 19 years in this hobby.
Seriously, cheap as it is, that servo will be a total waste of money. If you do buy it anyway, let me know how long it lasts, out of curiosity...
