Sparks

[vette1]

I'm using the gp3300 batteries without being shrinkrapped and I noticed when I picked up the chassis and hit the axcelerator sparks were comming from the batteries and they were extremely hot. I am wondering if this is considered a short and if that could stop the truck from moving. I am able to steer still but once in a while I push on the excelerator and the truck doesn't move. What are the chances if I shrink wrap the batteries so the metal connections are not exposed will stop the sparks and also eliminate the not moving problem. Its like there is no power going to the brushless motor at all, however sometimes it jumps like the power is on for a fraction of a second and stops five six times in a row. Also the receiver, fans and the servos still work when this is going on. Any advice what this problem might be if its not the batteries rubbing against the chassis. :007: :035:

A little frustrated as you can see, please help with any sugestions.

Thanks

Mark
