Go to a weaker winch motor. If the winch motor can't break the line, then the motor stops turning. For anyone who has used a F3b winch, you know what happens. The F3b winch motors will only draw roughly 500 Amps stalled while a Ford winch will go to 1000 amps or more. Then you live with the lower input power.

The 2-man tow setup puts a practical limit on F3J, but apparently that limit is 
not fully compatible with the standard U.S. winch setup; that is, it seems that 
the F3J scheme can launch bigger planes than our typical winches like to 
handle. One imagines a nightmare scenario where the planes keep getting bigger, 
and eventually as clubs need to replace their launch gear, they'll turn to 
super-power Injoy or similar winches, and the cycle will repeat, and finally 
we'll be flying models 40% of full-scale like the gas-power boys.
