OK im not a Flux guy but a nitro guy. However maybe you can taake an idea off the mod i did and incorporate it in the flux tranny. read the link below it might give you an idea. remember the small things sometimes help.

I know that the flux comes with either a 2speed or single speed but maybe you can take the 2 speed idler gear or drive gear and make it work on the flux.
Im willing to bet if you take the plastic gear and upgrade to the titainum gear off ebay you could have a pretty badass flux tranny. Im still a little nervous to try it on my own 3speed but modded piccos cant brake this tranny mod
