i bought a ball differential set for my micro rs4 pt#72450, my rear end is all stock,when i put it on only the spur gear spun when i tried to go. CAN I GET SOME HELP

Committed88

So I figured it out. My car does 25mph (really was 23mph, but I figure there was some offness on the measurement) with a 20t motor. I think thats not bad at all. I really liked the Mini RS4 frame, but when and if I need replacements I don't want to have to hunt around for years trying to find them... so I am going to get an RS4 Pro 4 in the next few months. I know, I know, its a big jump, especially since I jsut got into it. But I'm hooked, and I will race as soon as I get back to the states.

So I'll buy the Pro4, now I have another question. What servo should I get for it. I'm not worried about ESC or motor, becuase I've got those figured out (or transmitter or reciever). I don't intend to race RIGHT AWAY, but I will be. Something to consider, is that the car will be using either a 10t motor or the Novak Brushless, so it will move. Any suggestions. My reciever and transmitter are Futuba with a J connector, if that matters.

Thanks for the help in advance.

Also does anyone know a site that has better prices for the Pro 4 than tower hobbies, and will ship to an APO address?
