the battery packs on the hyper 7 are the worst design i ever encountered. I was running the hyper 7 outside in the back-yard, and the buggy lost all power and control. It went speeding into a bench. Then i took the body off of it and found the battery pack missing. Only the wires remained. What gives? What is wrong with the hyper line of buggies?

Not sure what happened. I never had that happen to any of my hypers.

If you are talking about the flat pack holder that goes on the side of the radio box, you are supposed to zip tie your pack to it. If you had it inside the radio box (using a hump pack) it should be held shut with an allen screw (or body clip, I can't remember). Either way requires that you forgot something, and thats why the pack fell out.

ya like he^ said, i have a hyper 7 and it is awsome no problems yet and i have been racing and bashing with it for about 4 months now

heres a pic of what happened.............

Yeah, you don't have any zip ties or velcro or anything else for that matter keeping the batteries from falling out.

lol yes use zip ties

i see

I have seen it happen on the touring cars they have...happens at our track in crashes.

love the hyper 7...wicked quick...fun fun fun...i learned real quick that ya gotta zip tie the batteries in or watch your buggy fly up over the hill jump the ditch land upside don in the road and get he by a car....my bro inlaw still cries when ya bring that one up..

Thanks. I appreciate the help

Remeber its better to put a bunch extra zip-ties then have that happen again. I use 4 zip ties (inbetween each battery cell) to hold the flat pack down on my PCR.

wow. 4 zip ties. I now use rubber bands. Ok, time to cut them off and put zip ties on. I really appreciate the help(X2).
