does anyone here recommend replacing the stock alum gear with a carbon fiber gear from Moose, or graphtech? I am going to put a OS 1.6 on mine, and trying to shave weight, also maybe replace the wheels for lighter ones. Not sure how it will balance, still in the building process, but already have Hitec 225 mini metal gear servos x2 mounted in the tail. Plan on using a Slimline pitts muffler since I head bad things on the bisson and the OS 1.6, any info on the gear and cg would be great
