The hobby shop replaced it under warranty. I got an eagle tree data logger and found out I was pulling 126 amps and pulling the pack down below 5V. For a while I still ran this setup but more closely monitered the temps. I still managed to kill a second pack. After that I got a different motor to tame it down a bit. I still run it from time to time but switched to A123 batteries and just run speed runs with it.

i was running DTX 4200s i've blown like 6 cells of them.. never really had temp problems..


on another note i have a buddy that would trade my 7700 for a 5700 mamba.. think i should do so?.. and if i do wouldn't i be losing speed and torque? i love poppin wheelies on demand.. i only bash but race cars up my street often.. i like to see their when my RC passes them.. i guess i'll opt for the 40c packs.. does it make a difference with a hardcase? because i bash the hell outta my truck and hardcase just seems logical.. whats the pros and cons of a hardcased lipo?

also if i swap motors i could go bigger then just 2s.. i think that 5700 is rated for 5s or 6s lipo..
