Breaking in HPI Savage GTXL-6 F5.9 tank 4-6 part throttle.

This is the final 3 tanks to complete the breakin in process. The goal is to get the idle stable and not varying between low and high rpm. As the piston and sleeve wears in, the internal friction should be lower so this would ensure the idle speed is consistent. Tuning the car is next using running fuel instead of breakin fuel.
