Re: Motor driven catapult gear ratio
Our Choo Choo winch consists of:
2 RS-775 18V motors connected with the VexPro dual input mount.
One VexPro Versaplantary transmission at 300:1 3 stages (10:1,10:1, 3:1)
winding a set 18:84 VexPro gears.
1400:1 total gear reduction
Pulling down 2 7" trampoline springs to 14" takes less than 8 seconds
provides over 240 lb stall load (unloaded output)
