I would try reprograming the ESC:

I know I had to send two of those back to Traxas for replacement as well. Good Luck !

19.5 volts on a silvercan? Not positive, but I don't think a silvercan would like that much voltage. Rated for 7.2 volts and will run slightly faster on 8.4 volts, but will shorten it's life. Motors are probably seizing up on that much voltage. The Evx-2 is meant to power a pair of 21 turn Titan 550's rated for 16.8 volts like in the 1/10 E-Maxx. These motors also come in normal and reverse rotation for dual setups.

hi

thanks for that bit of info

i have checked it on my 550 cosmo winch with 148:1 ratio and that works!!!

it seams that the evx-2 wont work on 540 motors!!!

now im after 550 motor,,,any body got any???any condition but must be working

thanks nic tt

It will run 540 motors down to 10 turns, but the motors must be rated for the voltage. Click me for specs. The only motors that I know of with this rating are the 21 turn (not 12 turn) Titan 550's. New these sell for about $20 USD from Tower Hobbies and could probably be found cheaper on ebay. These will produce massive torque and speed since they are designed to run a 7 pound w/o batteries monster truck to 30+ mph.

hi

my silver cans are standard tamiya ones and think there only 7.2v-8.4v rated

think i need 2x 12v 550 motors,,,but not 100% sure

[cubsfan2009]

You need a pair of these. <== Click me. Reverse rotation model. Click me.
