Just got round to rebuilding my cyclone - bought it second hand a few months back. I've been trying to return it to factory spec until I came across something really odd in the manual. The previous owner had a spool arangement on the spur gear shaft, but when built to the manual, there is a one way bearing. I built it as the manual but I couldn't understand why the bearing was rotating the wrong way. But then I looked at the exploded diagram at the back, which shows the spur the other way!

Not only that, but the amount of added rotating mass. I prefer (in rc terms) universals to "cvds" because they seem to last longer, and in offroad, do not collect dirt and grime to wear down the components.

I think the difference you are seeing is due to manufacturing tolerances most likely with the 2 pics you shared.

The cvd and universal assemblies are sorta opposites of one another. See picture below.

-The WCE CVD's use the MIP design. The driveshaft captures (goes around) the axle assembly. This does offer more efficiency at extreme turning angles. Not a huge difference.
-The TC comes with universals. The axle assembly captures the driveshaft.

To this date all Cyclones share the same basic geometry. Each new version just adds new tuning features that are compatible with ALL Cyclones. No major changes have been made in 4 years. The HB Team got the design right to begin with way back in 2005. Well... all except for the diff design. It took a few years to address that issue.
ok thankz for that i have just lost another pin so cvds are at the top of my to get list now

thankz for that

That's odd that you keep losing pins. Are they coming out right after an impact? Is it the same universal that loses a pin or is it random? Did you loctite the set screws?

I agree... that is really odd. Are you using a good quality 1.5mm driver to tighten down the set screws, or a simple L type allen wrench? Try to get a hold of a quality allen driver where you can tighten the setscrew down really well without the fear of stripping the screw out.

Also, when you are building your universals, its very important to make sure the threads in the couple stay EXTREMELY clean. Any grease/oil that is in there will prevent the thread lock from ahearing the screw and coupler together, allowing it to back out fairly easily.

One last tip... If you have a dremel or a small file you can griind a flat spot on the pin itself for the setscrew to tighten onto. This allows the setscrew to have a little more grip on the pin, and also if the setscrew backs otu a tiny bit, the edges of the flatspot could possibly help retain the pin as well.

Give those a shot and see how that goes. I personally didn't see a big enough performance difference with the MIP CVD's over the stock universals. The stock universals have been great so far and I plan to continue to use them.

No one loves you, and it would have been a great season for you if you would have kept your Cyclone.

Now go back to replacing your bearings in that tamiya, you have a B main to get ready for!!!
