Which Reedy is it? The older 2 pole, or the newer 4 pole? Reason for asking is you need to watch temps on the old 2 pole motor. They like to run hot. I'm running an older Reedy 3300kv 2 pole with a VXL 3s esc in my Stampede. I have it geared pretty conservatively at 18/90 and it will climb up over 150F on a 2s in around 10-15 minutes. It runs 31mph. I really like the motor for the application, but gearing up or running on 3s would probably fry it.
