Nothing wrong with Lipos in your receiver set up properly they will out last the chassis. We have had two Nosram 2200mHa 7.4 lipo's mated to the HT 6V Reg (the one with the heat sink). And they are on there 3rd chassis all i do is put 2 extra heat shrinks around the battery and use a thin foam to help "protect" the battery further. Thing i like about the Lipo is you get a constant 6v to the servos all day not just when you turn it on like a NIMH. Yes I've seen lipos fail in the receiver box but looking at how they were set up i was amazed it dident fail sooner.

thanks will look around
