Ok here goes, the belts that are being sold on ebay are only good for five five minute races before the rear belt obliterates. We do need to find a supplier that can make an exact copy. Other than that my car goes rather well and just needs a bit of work on the front end and its done.

Id say a 7.5 or even 8 should be good but a 5 only once we have come up with a resolution for a new slipper.

No pictures but the belt basically broke the bonds and turned into threads so rather dissapointed. I had the slipper running to and then when i tightend it slightly the car which runs silently other than the motor (you dont hear the gear mesh either) and sounded like something was binding, sounded like ujs but was the belt shredding into fluff.

Yes i agree. I also changed the bearings in the gearbox just to be on the safe side.

Front gear box
I have locked down the design for the front gear box.
It looks not as strong, but I have ran it through a FEA program, it is actually very strong after it's is mounted and squared on the chassis and front tower mount. I am going to get it quoted and try to make a sample. BTW, it does looks like the head of a cow. Bearings will need to be change to flanged bearings. |

Looks good, seems that my original cut away the rear and sides of the front gearbox has been picked up and yes would be very strong as the plastic sides are strong on my car. Hurry up fibrelyte with my cad drawing on jpeg so I can post it as well.

Here it is. This is my first design, I have not yet got around to starting on the rear gearbox mount yet but I already have an idea. There are only two plates on here so the main one with both together has not worked out how it should be but seeing as you can see both plates you can see how the one small item should be

The whole gear box (now mount) is designed using a flanged bearing. There will be only 0.2-0.4mm for the diff to move side by side. I believe this would be an easier way to solve this problem, as less parts on this gear mount, the less cost it will be. |

Pity I am no good at 3D cad but intend to get a proto made of mine within a week or two and will post some proper pictures of the made CF gearbox. If you have any input towards this by all means let me know.

Either than that, I think you have a good design there, incorporating the lazer zx-s's design. My original concept was about the same. But omitting the bottom plastic mounting and extend the cf piece all the way to the bottom. and the diff will be held using flanged bearings. After that, 2 aluminum mounting brackets will be used to connect the gear box, the chassis and the rear pivot block. Spacers! you need to anodizing them blue!! |

Welshy,
Do you think it's a good idea to produce the arms with aluminum? Or is the current plastic set be okay? |

OH!! I got a reply for a supplier that can manufacture the small pulley (LA-11) out of aluminum 6061 or 7075.
I might get the 6061 and hard anodize them if they are cheaper than just 7075. Will update you guys on that later on. |

I have actually finish designing the pivot blocks that uses the new lazer zx-5's bushings (LAW32) and the TF-018.
IMO, I believe that rubbing dissimiliar metal together is not a good idea. There will be more wear. With the use of the delrin bushing (LAW-32), I think it will be more smoother. I am not sure if they will be popular. If not, I will just produce only a few sets |

Arms, do you mean wishbones? If yes then the current ones LA26 are the strongest you will ever come across (evan harder than the YZ10) and is very very hard to break. I have only snapped one and that was hitting 35mph into a steel pole.
