hey last week i ran a 6.5r velociti motor with 20/84 gearing and the motor was very very hot and i noticed that around the 4min mark the motor started to loose power i change the gearing to 18/84 and it was still the same so i'm thinking there might be some thing wrong with the motor.yesturday i ran a 5.5r velociti with 20/81 all day and no problems at all the temp of the motor was just right hope this helps
