The 20 oz / in is the concern. They get hot and smoke. You should be up in the in /lbs ratings. FYI automotive A/C O-rings are perfect. Most shops or parts stores have assortments. The connecting arm for the belcrank to motor is a draglink arm for a T-max RC truck. A good judge of motor is the shaft size. smaller than 1/4 its pretty much a sure bet that the motor is to small. If you change the setup to two gears you get a cool 360 rotation. T-max drive gears can be converted to fit nicely.
