Glad I can help answer questions.
We always track test what we sell and we rely greatly on what our drivers report to us. So far the feedback has been great regarding the 3800. In fact one of our drivers TQed and set a new track record with them at a big oval race. At the HK REEDY race the 1st and 2nd place finisher in the stock class used IB3800 and we had one of our drivers finish 6th in the Invitational class so these results prove to me that the cells are very competitive.
