Some guys also punch small holes in their tyres to let the air out as they expand- whether that actually works or not I wouldnt like to say. My cure for burst tyres ( never had one, ever ) is to use Imex Jumbo Clawdawgs- they are soooo thick that they will happily balloon like crazy but never pop, just had to reglue them to the rim a few times.

HPI should send you some new diffs ( may need a picture as proof, no big deal )- if they werent bullet proof ones then they definately will, if they were bullet proof then they shouldnt have stripped; will have to dismantle them for inspection either way.

Only thing I can say really is to tone down the puch a bit and avoid the crazy burnouts and spins, those put alot of stress on the diffs vs normal driving up & down or following an imaginary track so to speak.
