The problem for such drivetrain:
- You still have shaft and 2 90' gear transfer, this will force you have to keep the chassis in high strength structure to avoid gear strip due to chassis flex.
- Torque steering will still there since you have armature/spur/shaft rolling 90deg against chassis line.
- Too many parts = potential trouble spot

For me I prefer direct rear drive in different way, replace rear belt with medium size gear. It doesn't have the weakness of both belt and shaft. There is similar drivetrain in JP but they have the motor facing left side rather than right side, bad for gryo effect.

First when read comments in this thread, I assume this is a big joke...

But when I re-think what Scooby had in his mind and what he had done at that multiple-revised drawings , maybe someday big manufacturers will use this design.

Cheers for you Scooby...
(I assume you don't make any real work at office today instead of drawing this car)

Ouch I draw something wrong....XDDDDD
Anyway it's the idea...

edit:
correct one attached

edit2:
Forget to mention, the shaft rear belt front layout also got another problem: wide front bulkhead. With a bulkhead that wide, you will force to use JRXS style front supension arm, and will be in very different geometric with rear arm, similar to 1/8 GP. I dont know if it's ok for 1/10 EP but that seems will casue some headache on developing suspension.

you people made my day
to really set this car appart from the rest you do the revo style shocks but it's looks great but isn't it a bit to long ? but i think you should contact any rc manufacturer and show some drawings and stuff.

greetings hollowman

this design looks like the original RS4 drive train. Gears to the rear, belt to the front. Unless that is supposed to be a shaft to the front?!?

New from the rumor mill is that Scooby was caught testing a "new" design by a Major R/C magazine.

Here's another idea for a shaft belt car:
Design Copyright G.Fab Racing. Not just ghetto, Ghetto Fabulous!

EDIT: Belts are hatched, shaft is shaded.

Explanation: Center mounted motor powers driveshaft that powers front wheels. Front diff is equipped with a differential for the shaft and a one way pulley. Up to 4 center one ways can be equipped for rear one way action. Car may be run with front spool but must be used with special rear drivetrain reversal kit. Servo mounts in front of the front wheels and the cells are in the standard hybrid shaft belt 2x2x2 configuration. Special 8 wire ESC will be included for maximum tuning with different cells. 2 NiCd cells may be used in the front for maximum punch and front end acceleration. Bulkeads not show, but will be made of a composite carbon fiber/nomex sandwich material for maximum rigidity and minimum weight.

You guys all realize the next logical direction for this design is a Losi Street Weapon, right?

I'm sorry to say this but that design is terrible. There's too much rotating parts on the left side, right side and middle. Battery placement is very complicated. There's going to be more complication on the "8 wire battery ESC". The battery wires should all be equal in length if that is the case, but more wires will be sticking out of the car. Another thing is the weight distribution. Have yu ever considered the CG? What the hell are you thinking? Apply some physics on your design next time please!!!



Scoobydo's design is unique and simple but will be considered in the future I'm sure. He'll make a lot of money with that. Have it patented Scooby!

perhaps if you moved the motor to the other side, that way you would have a 6 cell pack and only need a standard ESC
