The CVS for the corally PHI comes in 2 different forms. The standard and the option. The Option has the shorter axle and Longer Driveshaft as requested by the UK drivers to enable then to run the narrow steering knuckle and optional hex.

Will you be making spare shafts available any time soon?

Cool thanks...the axles on mine seem quite long so I probably have the normal ones. I've got the aluminum steering knuckles but didn't know there was any narrow knuckles. I'd better double check to make sure which ones I have as the axles have quite a bit of room between the pin and the bearing. I guess maybe I should clarify...I have the 08 Phi...was the narrow knuckles made for the 08 or 09?

Thanks

What's the difference between the fronts and rears?

My only worry is that 7075 in the front might get destroyed a bit too easily.

Hi Damien


The front has a slightly larger diameter Axle to ensure that there is sufficient steering lock.

We have tested the product with varying driver levels on outdoor and indoor tracks where they are prone to all types of abuse and from Nitro, 13.5, 10.5 to full lipo mod with cars doing close to 80 KPH doing hours and hours of racing and hundreds of laps (and crashes!).. The design appears to be more tolerant to the everyday impacts we get which is great.

One driver had a very heavy impact close to 70 KPH breaking wishbones spool cups c hubs etc, and all that suffered on the CVS a rebuild kit would take care of. Another driver broke a the whole side of the car including the top deck causing 90 of damage (not including the fan on his GM and the drive shafts were complete... (was looking at his transmitter flat out on the straight and hit a metal pit lane spike..)

As you probably also know the CVS comes with a no quibble 60 day warranty even if they are subject to an almighty crash. After that period (and within reason) there will be a small nominal charge for replacing or rebuilding or there are rebuild and replacement parts available should the drivers wish to rebuild themselves.

The material we use is L160 which is the aerospace & defence release version 7075T6 which is ultrasonically tested for any impurities and is generally used by them in high stressed areas..

From all the testing we think they are brilliant so much so we offer a warranty

can you measure the weight of one CVS shaft and axle for Xray Nt1?

Musti, the prototype CVS for the NT1 come in at approx. 6 grams a corner.

I forgot to check this tread, thanks Jon.

I think 1/8th offroad will be much nicer with proper driveshafts.

incorporate boots tough, so we can run them fully greased.

+1 on that suggestion, but for all the CVs.

I thought that the dogbone setup on the diff side coupled with the std universal joint / axle made a complete cardan joint, and would therefore make the axle run at constant speed in relation to the outdrive.

guess I was wrong.

I was curious about it, so I wiki'd the other night. Double cardan joints require input and output shafts to be parallel in order to be the same speed... Perhaps nearly possible (camber and toe aside aside) on the rear, but not with the steering on the front.

I'm not sure if the ECS driveshafts work only by reducing the angle of each joint, or if the two joints actually cancel each other out to a certain degree. I haven't thought through that one enough.

sure enough, forgot about that aspect of cardan joints!

the other thing to consider is that even if the diff and the axle were to be parallel, the outdrive itself still sees the driveshaft chattering.

props to litespeed for continuing the TiR tradition of making killer driveshaft thingies

So the option version has a pair of dogbones that are 2mm longer than the other pair as per UK spec Corally PHi 09 kits ?

So when you order make sure you use the correct currency, there is a check box at the top of the page for different currencies.
Could you please check then paypal transaction ending in 8101S. Something must not have been right then. My total was considerably higher.
