I ran the vxl motor today for about 45 minutes with only a short battery change every 15 min and I could only get it to 160 with gearing at 19/90. Esc was less than 110. Today outside temps were probably 30 degrees cooler than the other day but I don't think that should mean my motor temps will be much higher when the weather warms up. I really couldn't tell a difference in runtime between the two motors. We'll see how it holds up as outside temps rise.
