Ive done a search on 3.8's but havent found what I wanted to now. Want I want to now is at the hobby store I go to they have one but dont warrenty nothing on it cause it says it could fry your car. I dont now what brand it is because its just in a lil bag. I asked how will it fry it and he said the entire board gets fried. Now I asked a guy at the mall who just sells bits and shen qui clones and he said it wont fry it but they dont last long and the motor itself could fry. Who is right if either?
I'm sure the motor wouldn't fry the car.....All the motor would do is burn out. The best thing to d would be to buy it off this site, if it burns out or whatever, you can get a new one. Those motors are not 100% gauranteed they will work good.
I really doubt you'll blow it up. Ive been doing soldering stuff on the motor tab which is a lot hotter than the motor will ever get. Hasn't exploded yet.
