difference
 

i was wondering whats the performance difference betweenthe wanderer 7xl and the 540c 7xl?

Performance? None AFAIK. The C motor has a built-in heatsink and screwed in endbell.

so other than that theres no difference?

On the inside, they're the same. The bolt patterns on the front endbell are different, with the 540C having a similar pattern to normal brushed motors like in 1/10th scale, and the regular 540 has a square pattern.

ok, thanx
