Losi Late Model Rules Update

We're making some changes in our Late Model class rules. The intent is still to keep costs for a competitive car under control. Our "house" Late Model class is essentially a stock class allowing only normal tuning and upgrades designed to limit breakage or maintenance costs. If 3 or more racers show up with cars with more modifications we are willing to run them together in their own class. The changes from our previous rules are to allow Mamba 4200 KV motors, and some selected aluminum aftermarket upgrades.

Stock Losi Mini Late Model - run "out of the box" with the following allowable changes:

- Changes to springs / shock oil / spring spacers / internal limiters. Losi Aluminum shocks are permitted.

- Adjustments to toe & camber. If a racer wants to upgrade to the Losi titanium link set / heavy duty ball cups to minimize breakage, we permit it but don't encourage it. The use of aftermarket steering bellcranks / links is permitted.

- Any Losi tire / wheel combination made for Mini Slider or Mini Late Model (we've found the stock tires work well on the carpet right out of the box without needing CA or traction compound)

- 6 cell NiMH batteries only. Maximum 1400 mAhr

- Stock motors. Brushes & springs may be replaced. Due to the need to replace the stock motor frequently we have decided to allow the use of the Mamba 4200 KV brushless motor with the Mamba 25 or Mamba Sidewinder Micro ESC. We've tested this combination against stock motors and found the speeds to be comparable with the maximum gear ratio noted below.

- Stock differential (shimming allowed) or Losi Ball diff (PN LOSB1125)

- Electronics: Stock receiver, ESC and servo must be used. Any compatible radio may be used.

- The pinion / spur gear may be replaced to alter the gear ratio. If using the Mamba 4200 KV motor the spur gear must be 58T or larger and the pinion must be 22T or smaller.

- Stock body must be used but custom painted Losi clear bodies can be substituted for the RTR body.

- Fasteners may be replaced with alternates of same size

Please note that the motor rule change does not apply to the Summer Carpet Oval Series events. We don't feel it is right to change in the middle of a points series. So for these Saturday events, stock Losi motors must be used.
