I have an idea, If you took a ZZSE's 2.4v dual cell pack, put it in front of the normal battery, and wired them all up, it would be just like an internal Tri-Cell. Then, Stage 2 MOSFET it and use a 3.43:1 ratio with a 4.2 King and it will smoke any Micro RC you can think of... well... maybe not every (muhahaha
)...
Kinda like this \/
