I have had a brand new Aftershock (basically an lst with a FOC tranny) sitting around for a while and finally came up with a good brushless setup.
Going to run a KB 45 10xl motor (1200kv) with a CC Hv 85 esc on 9s lipo. I have 2 5000 20c packs, a 4s and 5s, to use. Going to leave the 2 speed and mech brakes on this one, and the stock gearing too.
I plan to make 2 battery trays, one where the stock gas tank goes, and another in front of the tranny, behind the steering servos. This will require an modified brake servo mount, but it looks like there is a chassis cutout that will work with some modification.
Anyway, just got the hv 85 and the TiN coated diff gears. I also bought a set of HB hardened diff internal gears. I do not know if they will work, but will give it a try and post the results.
Heres a few pics, more to come!
