Anyone frying Nimh packs with stock 3905 E maxx?

[sikeston34m]

I've been trying to help a friend of mine with his stock E maxx.

The truck is brand new and completely stock.

So far, it has totally destroyed 2 sets of 7 cell Nimh packs. The first set was a pair of Electrify Great Planes 3000mah packs. They were brand new but turned into sizzling bacon during the first run. After about 10 minutes, the shrink was melting off, they were blazing hot and several cells were leaking.

The second pair was a set of 3800mah packs rated at a 38 amp discharge rate. Again, they go so hot, the shrink is melting off. It appears to me that 3 cells in one pack were about to burst. No leaking this time, but they're shot.

His motors are fine. Drivetrain is fine, no binding or anything. The ESC runs somewhat hotter than I think it should.

Just wondering if anyone else out there is running into this?

Any thoughts?
