About the RW spur, that actually sounds good. if read you right, that means the current spur is 4mm? All i have to do is ream or drill the spur to 4.7mm and it will fit good. I have just done revising my drawing again as i find that the optima mid shaft is a little under the perfect diameter of 4.7mm, its 4.6 so my spur is sitting a little bit offset, i actually have to push it nicely to get it completely concentric. its acceptable on the optima mid cause i can just place some kind of tape to cover the shaft, but for the Lazer i am changing the drawing to a perfect 4.7mm. I really hope the machinist will be able to make a perfect fit like the original B4 shaft. otherwise maybe no need to remake the RW spur at all, why not just leave it as it is at 4mm, and let each user ream the hole themselves?
Of course that is one option so that we can use up all the current RW stock. Also could you send me one additional used spur to give to my friend ? That one does not have to be perfect, perhaps something that you consider not good enough for you to use in a race. sending you an email now.
Also another ZX question, i am now considering rebuliding my ZX, and it has the original fiberglass chassis. i wonder how strong is this chassis compared to the graphite. i snapped my optima mid graphite chassis and i dont want to snap my ZX fg chassis. i am going to use the fibreltye top deck.

I only have new spurs, which cost me £5 each, so will send you 2 and your friend can sort you out with some money which can go towards the overall cost of the shaft your doing for me (I hope I make sense).
Chassis in GRP is flexible and my own opinion is not as strong as carbon fibre.
Spurs I guessed so cant confirm what size difference there is in the middle hole of the B4 and kyosho spur. I will measure the spur I am sending you and update you later on today.
My gearbox design is based lightly on the ZX-S design and will be an exposed gearbox. Its really down to how dirty the area is your racing on and if you want to cover it I cant see it being to difficult to do with either plastic or heat shrink (if you can find a big piece). Personally I wanted it exposed as you will be able to see the standard of the rear belt and in my design I am adding a tensioner at the very top over the layshaft pulley as well as below in the under side middle to give tension to the belt. The little tiny holes above the bearings are for a washer specifically made to hold the bearings in. The holes should now make sense on my picture. Plus with these lovely blue belts and all the blue bling I currently have on my car this will look superb!!!
