I only got about 4 hours out it with about 14kwh. Gonna do what I can to extend that by going down a tire size, putting thinner gear oil in everything 85/140 now, lighter wheels and more weight reduction but will still be adding another 7kwh when I find some. The dc motor actually felt cool to the touch when I would stop. Did have a 12v fan on it this time out.Can't stop watching these. How long will it wheel for on a charge? Do you feel like the dc motor is overheating?
