Scoobythedog - 3/3/09 at 09:40 PM

I'm looking for some reference on how the bec boys deal with the rear dif,

I have always been CEC, but fancy the look of the single seater under development. Is they anywere I can find out more on how they get the power to the rear wheels ?

If you mean for a mid-engined car then search for "chain diff" on Google and/or on here and you'll get lots of pics and info.

If you mean front-engined then you simply buy a prop adapter that lets you bolt the propshaft to the the shaft where the sprocket would go on the bike gearbox. Search "sprocket adapter" or "prop adapter" for pics.

Ive also got a mini diff and sprocket if you want to go that route.

Just choose a prop driven bike engine like my one

quite sleeve, bit of welding into a chopped prop, standard diff and job's a good'un....

Just make sure you pick an engine with the correct prop rotation or you'll end up with 5 reverse gears and one forward.
