Hey guy's, Not sure where to post this but here we go. Picked up a used 2wd slash off cl. It's a 1/10 scale with a dynamit tazer 4000 brushless with matching esc. Took it up camping and everything was great, Bashed the **** out of it lots of fun. I'm using a venom 5000 20c lipo battery charging it with a traxxas id charger. All came with the car. Now I'm starting to see where I cant let it get more than maybe 20 yard away and I lose control of it and it just rolls to a stop. What shoud I be looking for to fix this. Thanks
