Hey all.
Could i rig my jeti to power twin 380 motors...or even possibly twin 550 motors? If so, how could i go about doing so, with out harming the ESC.

i ran my jetti 600 with twin 380 motors. but only use it for a few minutes then switch my esc to a XL-10marine by traxxas. so i didnt have a good chance to put it to used nor did i wanted to really risk it.

Wire them in parallel. It will depend on your set up to determine weather it will handle it or not. two 380's definitely, two 550's depends.

Hmmm. Well twin 380's with two 6 cell 3500 batteries??
Do you think this will work?

yes, I know the Jeti will handle it, and I am pretty sure the 380's will handle 6 cells each. Just make sure you wire the batteries in parallel also.
