so i have a extra Revo it is a 2.5 frame. I also have a OS .26 on road four stroke engin with the kyosho conversion kit to get the steel fly wheel and other parts i needed... big block motor mount the list goes on and on. I have done this motor in a revo before but i was trying to get it to hit stock 2.5 top speed and that did not go so well. Fast forward 8 years or so and i am doing it again. This time I am making it a crwaler truck but have ran in to a problem... GEARS. To get the speed i want i need a 13t clutch bell and a 50t or the 54t Jatio spur would work. The Jatio uses 0.8m pitch the revo uses a 1.0m pitch and the OS .26 clutch is the size of an 1/8 scale. What seam to be the problem you ask, 1/8 scales also uses the 1.0m pitch and that wont work with the 0.8m Jatio gear. Does anyone know of a 1/8 scale clutch bell that is 0.8m pitch or a 1m pitch 50t or 54t spur that will bolt up to a revo... Thank for the help guys and i will try to get some pics up there soon.
