We also have a reduction after the toughbox mini with a 19 tooth gear driving a 48 tooth gear. I wanted to know of any gearboxes that really gear the motor down and offer a lot more force. Also if the difference in power between cims and mini cims is significant enough could this solve our problem? If you could post a link to the website for the gearbox it would be greatly appreciated.

On our winch, we used an RS 775 with a 1:100 versa planetary gearbox (1/2 inch Hex output). We estimate that it takes about 50-75 lbs to pull the catapult back and it does so in roughly 3 seconds.
P.S. Our spool has a 2 in OD
