I threw the receiver in my XXX-T , as that's where my QC2 was installed. Initially, the truck performed the same way it had before when I had the SR3000 in it; sputtered and studdered at low throttle. I tried the Voltage Protector, same deal. Next, I installed the LRP Worlds Upgrade Kit with the larger capacitor on the ESC, perfect. I next tried this same setup and removed the voltage protector, perfect. I tested this same setup with a Kokam 3200 2-cell Lipo. When I plugged the ESC into the low-voltage protector built into the pack and plugged the other other side into the receiver. Same thing as before, sputtering and cutting out. I went straight to the receiver with the ESC lead again, and it was awesome. OH, forgot to mention, this was all tested with an Orion V2 Element 19T motor. So I think the key really was installing the power cap on the ESC to prevent the voltage drop from going too low. I'm very happy with my testing results.
