Mike, get a tq booster from someone at the track. I'll show you mine on Friday night. You just solder the wires to the terminals on the esc and plug it into the receiver and use the switch on the booster. No extra pack to charge, no extra weight, don't have to worry about anything. You just need to plug a 2s pack in at the start to change the lipo cutoff and set it up using a hotwire .After that 1s will work fine to setup boost using a hotwire.
