Mardave COBRA Build..FIBRE LYTE..

Driveshafts !!!!!!

Well not much to show tonight, as I have had an issue with the Driveshafts !

Not ever owning the standard diff. I have the new EVO diff. Well I would say the outdrives do not just have a wider diameter, as with a early post I showed the gearbox holes needed reamering for the outdrives to spin free. They are longer or the diff screw/nut is bigger.

The reason I say this is that the driveshafts are now too long. You can not get up travel enough for the shocks to work, with this length of driveshaft. Which is a real shame as the New EVO diff is a nice bit of kit and really smooth.

So if your reading this Mardave. Make your driveshafts 6mm shorter pin to pin.

I have spent most the night playing around with another driveshaft and have got this to fit perfect. Along with shims and TAMIYA pink marshmellows....

I will show complete pictures tomorrow of the above to help other COBRA runners or builders........:thu mbsup:

So with the driveshafts, I had spare sets of Tamiya Top Force dog bones. After measuring them I wondered if they would fit, and after shimming them and using the famous TAMIYA PINK Marshmellows they worked perfectly.

Shiny top driveshafts are Mardave, Bottom dark are TAMIYA....

RPM White Ball Ends and TRF turnbuckles all made up ready to install..

Would these fit the rear. The front worked very well and were perfect. I wanted the rear to fit also as I don't like odd turnbuckles.

So the hubs went on to perfection. The hinge pin was a little bit of pain, but once fitted are perfect. And the turnbuckles fitted like a dream.....

First pic shows the little TAMIYA Marshmellow, Can you see it Dazza....

After looking at these rear hubs.... This COBRA was released around 1991 I believe. I may be corrected on this....

The cougar 2 works was around 92. I can see the similarity in these hubs and the works rear hubs... As the cougar 2 sport/race/team had the chuncky rear hubs.....

So with the rear end complete. It was time to make the wing wire. I ordered the wire off ebay.

Wire for wing.....

After looking at this, it was easier to cut and bend two single bits of wire. I wanted to keep them as short as possible to prevent bending. With these installed they are both very strong and will need a hard hit to bend.....

With the wing wire made, I had a spare Top Force wing mounting bracket that worked perfectly with the wire and Top Force wing wire mounts....

All ready for the Wing Now.............
