Much better belt on that. And you could add an rc10 hyperdrive on the spur side of it.bdrmbully wrote:Ah the good ole hyper drive. I had a track master belt drive in one of my older ultima.
Based on your experience, can you recommend a reference for calculating an appropriate belt width for 1/8 and 1/10 scale off road?fredswain wrote:Grunger73 wrote: I designed industrial belt and chain drives for oil drilling applications for almost 5 years. The problem with the hyperdrive and most belts on rc cars in general is their size. They are undersized for the power levels. Size them properly with a wider belt and they are quite strong and reliable. The parasitic drag is always going to be higher with a belt than a gear. Even a gear system that changes to a right angle such as modern shaft drive 4wd cars. A proper chain drive, in spite of it's other shortcomings, has less power loss than a belt drive. There is a wonderful shock isolation characteristic of a belt drive that makes them very smooth but unfortunately since they require some form of tension they add a side load to the shafts that they are attached to. It's all about tradeoffs and compromise.
