Do any of your guys know what is meant by 'degree' with regards to tyres. and how are Power tyres?

Power tires are quite good. They are from GRP family of tires.

Can you give an example of what number is associated with regards to the "degree" of the tire?

This is what it looks like, it looks like shore,

Proline Nitro Shoes 26mm 35 DEGREE (0 OFF-SET)

What are proline nitro shoes like? I may just go for GQ, I know for you Dee, they dont last long. I am thinking of getting a body for Tower, maybe I will get tires too from them as RC-Mushroom dont have many.

Never seen it exrpressed like this, but it must mean the shore of the tyre, i.e. the hardness rating.

Sometimes it does happen - they are normally quite quick. It depends upon what you order - if it is something which not a lot of people order then it takes a bit longer. I'm waiting for a light weight propellor shaft for my Surikarn (sorry for swearing ), which may take a while to get in stock.

Standard dogbones are universal joints. A pin connects both wheelaxle and driveshaft. When there is an angle between the driveshaft and wheelaxle, the output speed is not the same as the input speed, but forms a sinus function with the input speed as the average. I think the 3racing joint is a universal joint, the only difference being that the dogbone is fixed inside the wheelaxle, so you don't lose your dogbone so easily.

A CVD (Constant Velocity Driveshaft) is constructed in a different manner to eliminate the difference in output speed. A good example is the homokinetic coupling thats used for driveshafts of most modern cars.

BUT, two universal joints at the same angle eliminate the sinus effect. The first one induces a sinus to the dogbone, the second one creates a sinus with a difference of half a phase, evening it out for the wheelaxle. If you replace one universal joint by a CVD, the sinus effect of the first universal will not be evened out.

So in other words; If it's a CVD I don't want it!
(If it's a universal and 3racings usual quality I don't want it either)

I know what you mean although you lost me when you started talking about an allergy (sinus). I must just say that a dogbone has a lot more friction because the pins 'rub' in the cups but with a 'universal' has les as it runs on an axis with an axel and another axis with an axel at 90 degrees. if you understand what I am saying. A FWD car has CV Joints or I would imagine CVDs, if they work for big cars, why not for little cars... Dont get me wrong... if it isn't made by serpent, it isn't made for me. If serpent releases CVDs, I will look at them, but till then, I will not.

I could not find a decent picture of a CV or a CVD, but here is a universal, I mush more efficient joint if you ask me...

Err... sinus... Don't know if thats the right word in English. It's the sin function on a calculator. (sin, cos, tan)

www.freetranslation.com isn't helping either!

OH, I see what you mean... SIN. Try this site for an explanation.
