I don't know anything about a Cliff Climber but your best bet is probably to buy another stock ESC unless you want to upgrade, which will not be cheap. [sm=50_50.gif] I mean, you should be able to use just about any ESC, 1:18 or 1:10 scale, in that rig but most will not stop your truck from rolling on an incline unless made for a crawler.

I use a Novak Rooster Crawler ESC in my AX10 but it would set you back about $90.00. []
