New Brushless With Some Issues

[HotnCold]

Which motor are you running? How many batteries are you running ? You ran in First gear for most of the run and the motor was pistol hot? That could come from over gearing or under gearing as well. Was the motor that hot when you were running in first gear as well or only after you switched to second and then ran the heck out of her till the batteries dumped? A heat sink would be a good decision - they are in the RC-Monster Store and are very inexpensive. Probably the best thing for the buck you could get... Its probably impossible for you to run shifting between first and second gear and not be under/over geared. Its probably wise to choose one gear - gear for that gear and leave it at that. Hope this helps ya out a little. List all the factors (motor, batts, gear, etc ) and there are a bunch of very knowledgeable people here that will help you get her dialed in in no time.....
