Default CVT Gearbox

Dear Buddies,

As we all know, 2-speed Gearbox for RC car has always been inefficient.

May I know if there are any CVT Gearbox for RC car out there ? Or the scientists and engineers out there need to put more effort to make the RC world more wonderful ?

Thanks

Victor

like a belt drive on a snow machine or my 4 wheeler? I think its a little too complex for something like an rc car with a massive power to weight ratio. Direct drive and 2 speeds are all you need

In the past I have seen a picture of an old 1/8 2wd car with a self made CVT.

Look at the construction of a centax clutch, you can use that technology to create a CVT.

A long time ago in a galaxy far, far away a manufactor by the name of Thorpe made a cvt tranny for a 1/8 scale pan car back in the mid 70's. I had one it was hard to setup up the tranny just right but LOOK OUT when you did get it adjusted just right !! The car was really fast but my car eat belts , it would stretch them or snap them. I suspect that belt maintanence would be a big problem with this style tranny on a rc car perhaps this is why no manufactor has attempted making a new one for todays 1/8 scale onroad cars. Here is a picture of a old thorpe car

Like ouch...

For the record, writing something in all caps, or blowing up your font size, is the real world equal of walking up to someone, and shouting an inch from their face, it's terribly rude.

I thought I was the only one who noticed that the font was TOO BIG. Maybe he's sitting too far away from the screen?

I think the modern CVT concept can apply on RC. Also relate to spinning something and centrifical force. But the point is, how to guide the drive belt and the material of the drive belt.
