Losi Xxxnt Rtr Sport
 

I HAVE A LOSI XXXNT SPORT RTR, I JUST REPLACED THE NUT IN THE TRANNY THAT TIGHTENS THE REAR END. I PUT THE TRUCK BACK TOGETHER WHEN I GIVE IT GAS THE TRUCK REVS UP BUT DOESNT PICK UP MUCH SPEED. I DONT KNOW IF THE TRANNY IS TO TIGHT OR LOOSE OR IF THE CLUTCH IS SLIPPING PLEASE HELP IF YOU CAN MY EMAIL ADDRESS I [email protected]

Either your diff is too lose (very bad) or your slipper clutch is loose. When you turn your rear wheels, do they turn with some resistance, or do they spin freely? If that is the case, your diff is too loose and you need to tighten it before you melt your diff gear. If it is tight, tighten up your slipper clutch.

the diff nut is prob stripped from being over tighten. I did this when I 1st got mine. go here http://www.radiocontrolzone.com/foru...d&pagenumber=6

diff
 

sounds like your dif is to lose, you can tell this by holding onto your right rear wheel and you spur gear at the same time, then try to turn your left rear wheel it should be hard to turn. if it is easy to turn ya better tighten it cause youll melt the dif. then keep checking it every couple tanks of fuel.

Diff Problems
 

As I have learned the hard way, make sure to brake in before you race it. I have blowin 3 set of diff gear trying to rush it at the last minute. I now know to get the diff tight then run the slipper abit loser for the first 20 mins of running, checking your diff every 4-5 minutes or so to break it in right. This is just a warning to anyone else with this truck, so you don't make the same mistake I did.
