1-12 Scale news, LRP SXX version 2
Things are going at a glacier pace here. I had planned to test the car with a SXX Stock Spec Speed control and a 3.0. I had the car running on the bench. The specs suggested a 4.5 on 2 cell LiPo was possible. I thought maybe a 3.0 on 1 cell might be handled. It spun the tires OK. I plugged in the LRP fan for mod use. Then the speed control failed. The speed control spent more than a month at LRP. They were waiting for a shipment of SXX version 2 TC spec. Based on my intended use they though it would suit my needs better and offered to trade up. I accepted. Turns out the version 2 has an upgraded battery eliminator circuit (BEC) and will work with one or two cell. GREAT! That is why I had the stock spec in the first place. Anyway here is a current pic. I put a LRP X-12 4.5 on it based on some one cell dyno runs I had performed recently. (The 3.0 pulled a huge 209 amps on a flywheel run, a 3.5 actually produced more power. A 4.5 is pretty close) I may be able to tinker with the speed control motor profiles a little with the 4.5.

The car is a home modified CRC Carpet Knife, now with a dual A-arm front end, 3-link rear end, with hydraulic dampers from an RC18T on all four corners. The intended use is a bumpy long outdoor track.
