I have a MOSFET installed but I think there was something wrong with the way it was wired (there was a wire from the battery connecting directly to the switch which I believe is wrong).
I am considering down grading to a 7.4 buffer tube lipo or a crane stock NiMH. If I were to go the buffer tube route would I need to replace my buffer tube? I am aware that there are some after market tubes that have a slightly larger diameter but I dont know if it is necessary.
Definitely go with the buffer tube LiPo. It will open all sorts of options and LiPos have a lot of nice qualities in general.
For size and fitment, you should be ok as long as you use a small stick-type 7.4, like the G&P 1000mAh 7.4V LiPo (for example -- there are a couple others out there that fit this profile). It fits in some really small places, I have not yet seen a buffer tube that it didn't fit into. A teammate of mine has managed to fit the 1200mAh G&P stick into his buffer tube on his G&P CQB MOE, so there's definitely some room in these buffer tubes.
Side note, the G&P stick is small enough that I've managed to cram it into a KAC PDW handguard (albeit after some modifcations). Try to spot the Deans-wired 1000mAh battery!
