The heating was very apparent when we upgraded our original single motor 9015 to a single 0673 for hopefully improved recover time. The motor direct drove the shooter via the AM 3.7/1. When a ball was shot with the 0673, the current peaked at 30 amps+ and then ramped back down to normal over the ~ 3-4 seconds recover time. If during testing, you shoot a couple of dozen balls one every 3 seconds, that's a lot of heat the motor has to dissipate. In the competition, I suspect we would be lucky to shoot 6 balls over 2 minutes (at nowhere near full power). My original post was basically to highlight the quite visible effect of the higher KV motor had to our wheel speed (too much, had to slow it down with sprockets) and the increased power consumption (and risk to the brushes/motor life) that followed the extra speed.
