Let me start by first saying that I LOVE MY LOSI MICRO SC! I have spent countless hours indoors running the Losi Chassis on my Living Room Carpet Floor. I have re-arranged the furniture to make way for a track. I have made jumps and obstacles out of cardboard boxes, magazines, broom sticks and other miscellaneous furniture. I have even marked my lane with 3" blue painters' tape. As I said, I LOVE this truck.

Not only is this truck a blast to drive, but it costs only $110.00 on the street. COMPLETELY READY TO RUN!!! The electronics are at least as good as the Mini-Z AM boards, AND they handle voltage much better. The little chassis also comes fully ball-raced and with Big Bore Micro Oil Shocks. It includes a NiMH battery pack and charger, plus it even includes the 8 x AA batteries that you need for the transmitter.

There are 3 complaints that I have though:

1.The Drive Train binds WAAAAAAYYYYYYYY too much.

2.The Battery pack last WAAAAAAAYYYYYYYYYYY too little.

3.The Truck is too slow.

With that, we set out to see what we could do with ours, examining the possibilities for upgrades. To deal with the Bound Up Drive Train, we opened the truck up to see what we could come up with. What we found out is that the differentials are too tight inside the gear cases. This causes the diff action to nearly lock up and it also makes the drive train strain entirely too much under power. The result is decreased run time, over heated electronics and slow speed.

What we came up for was a really simple solution. All it took was 2 narrower bearings and a couple of M3 0.3mm shims. Below is how to install these in your truck.
