I have a LST2 converted to brushless...Hydra 120 and Feigao 8XL.
I've never had a problem with the ring, pinion, or diff bevel gears. I don't htink the Hot Bodies gears will work...they look different. Have you heard of someone who has used them?
No, but I figured that I would give it a try. I have a few other hb diffs so if they do not work I can use them as spares. Plus I am going to try the lst diff mod for my tmaxx, always good to have spares!
Hey guys, if you wnt to use HB internal diff gear, think to the Kyosho to the place. They fit the HB cup and are way stronger. All the guys runing HB LSP and brole theyr diffs had switch for th Kyosho and no more troubles.
