I have a Fine Design XLT1 in my LST2 which is basically a 7XL. I just ordered a Neu so I'm hoping it'll make a huge difference. I got used to the XLT motors and want more now.
I have an aftershock, and intend to use a KB 45 12xl motor on 8s-10s lipo. Leaving the stock 2 speed and using Mike's 2 speed adapter, which I had him bore out to fit the KB 6mm shaft.
Going to leave the mech brakes and use a CC hv85 esc with a pixstix adapter. Most likely going to use a pair of 2200 20c 5s lipos wired in series.
Batteries should be good for nearly 2hp, hope that is enough. I may have to buy some larger capcity 5s packs, we will see.
