Hey!
you asked which one of the following two car was better: tc3 or pro 4

You never said BMI....
because now I can argue that BMI pro 4 is better...

name some of the things that bmi pro4 is not better over bmi tc3!


lol...
TC3s are good cars. I am sure you will be happy with yours when you get a bmi chassis.

TC3 is a good car winning races sice it's debut...





If you still use stock gearcase with bmi tc3, your tc3 wouldn't be smooth as a pro 4

pro 4 is purple

pro 4 has awesome antisquat/kickup and rear antisquat adjuastability

pro 4 has niiiiiiiice steering system consisting of 6 ball bearings

pro 4 is "tuff"

Default Building the Pro-4

Super Steve;

The Gap in my Gearboxes is at the case halves, right where the outdrive bearings are. Yours look pretty good from the pictures.

I don't think that the Gap is there on purpose. Why have a Gap when you could design the box from the start to have the proper bearing fit?

Precision molding plastic parts is a very tricky science. The mold has to be designed to compensate for the plastic shrinking after it cools. If anything changes even slightly during the molding process, you can end up with bad parts.

Now I'm just not sure what is the problem with my Car. I just know that the Tweaking I am seeing is NOT acceptable to me.

I now have a new Upper Deck and 2 new Gearbox cases coming early next week (paid for).

Thanks,
Steven

Pops,

I thought you meant when the gear boxes were not screwed down. Mine has a little gap w/o tightening down the screws. When it is tightened down, it is like steve's, no gap....

well i got a pro4, raced it for the first time on saturday.

i am very pleased with it so far except i found on a slightest knock the ball joint came out of the chub/steering block but threadlock soon cured that

i only qualified 7th in the B (not good for me ) but worked me way upto 1st after a bad start....my lap/times would of put me 5th in A (good for me )

i am very pleased with the one-way, also it is the first time i have runa one-way.

i had no problems with bevel gears, cant see any tweak problems.

and also pops....i have no gaps in my diff halves

most people are saying the bevel gears break first but if you boil them it softens thema bit and you shouldnt have any problems with them.

make sure you shim your diffs right to.
