hpi savage flux?

i was thinking about getting it but was wondering what ahve been the problems with them so far? im planning on selling my emaxx with mmm and maybe even lipo minus motor to get one. can you use the FLM savage conversion chassis with the flux? since i like having just one pack and having it protected inside the chassis. im jsut a basher and my emaxx just doesnt seem like it will handle all the abuse. thanks
