A buddy was having some engine problems with his Ram 750, if he had a failed start and restarted the engine without charging the ECU pack his engine would fluctuate RPMs at idle, usually idling around 50-55,000 rpm and would not drop any lower. We decided to try a Duralite Plus ECU pack and not only has this eliminated all the odd engine surges he was experiencing but he can now fly 7 to 10 flights without having to recharge. Just thought I would share....
