Avid parts are more widely available then it was a year ago. You can have your local hobby store contact me directly. I will be more than happy to set them up as a dealer. This way you can get parts faster and easier. It will also help on shipping. My number is 1-949-705-6668. There are no minimums and we do special orders.
ok thanks ill talk to my lhs about ordering parts. kinda hard to go to the hobby shop when its an hour away and i dont have my permet yet Thanks again and cant wait till i race.

Hey James,

It is not only the top and main chassis pieces. That prototype looks like it is easier to maintain and setup. Look at the roll center adjustments on the shock towers versus the ones we have now. To adjust ours, you have to remove the diff to get the screw and move it over then reassemble. It is a world of pain. It gets even more frustrating when you are more in the pit than out practicing and playing with setups.

Other than that, the car is damn great. Not too crazy about where the steering servo sits or how the steering is setup, but it is a car with potential.

Not really. You can swing the carbon plate out if you only take the screws towards the motor out and just release the other two. That allows just enough room to put a screwdriver from underneath to undo the balljoint screw and work on the links.

But there is a major improvement in the fact that now the bulkheads have caps over the diff bearing holders as many of the other cars on the market. This is going to make a huge difference when working on the diffs indeed.

Another old feature is present which has all but disappeared in other cars. That is the rear bulkhead which is one with the motor mount. Tamiya (and others) have worked out that the car has more flexibility if these are separate, and have changed their designs accordingly. I think this was the way to go for the Avid too.

Another thing I find annoying with the current Avid is the whole spur assembly with the center pulleys which is a pain to service. This should have been modified to be in line with standard designs too I think. There is no point to making peoples life difficult and I feel inclined to modify it to accept a standard assembly to make my life easier.

What AVID are you talking about? The carbon plates were a bear to put in from all the parts fitting I had to do, not to mention unbend the bulkhead/motor mount plate so it can fit onto the chassis. The carbon fiber braces had to be shaved down in order to fit. Unless I got a dud car, I don't follow what you are talking about. Swinging them out is not possible. They are a tight fit as it is.

But yes, I also agree about the center pulley. It could have been done much better than the way it is now.

The car in its current form is great for asphalt racing and possibly foam. But not for carpet until that prototype chassis comes out. I just wish they changed the steering servo position as well. The position it is in now is ripe for binding if you hit a wall wrong or get T-boned.

The old Avid. But it's true, the front carbon plates swing out as I explained above, the rears have to have both screws (front and rear) taken out and then they slide out. Not easy, but doable. I have done it. If I had to take the diff out every time I would sell the car instantly.

And I know what you're talking about with the tight fit of the parts. After sealing everything with superglue, things don't get any easier either. But with patience (and a bit of grease) it gets better. I think some of these parts are manufactured to a very tight fit and it's possible that being so skinny they get distorted easily. This is some homework for Robitronic to get on to.

Not sure, but they're the same size as every other pulley on the market. Compare the belts if you want to those off a TA05 or whatever other car you happen to have handy and you'll see. Thank god, at least that's the same on all cars.

One diff that should be a good replacement for the rear Avid diff is that found on Kawada cars, but don't quote me on this one. The similarity is that both have the pulley in the centre. The problem may be in the distance between the outer bearings (the big ones) which may be smaller on the Kawada diff (single belt car, right down the centre).
The front being offset should allow more options as there are a number of cars with similar diffs.
