This is probably not the right thread/ forum, but if someone could put me in the right direction I'd appreciate it.

Im looking for a really cheap/ good online webstore (based in the US). I have been shopping at Tower Hobbies and the Integy webshop. The service is good but the prices isn't that great
I'm looking to buy TC3 parts/hop ups and electronics (motors) mostly.

Also, does anyone know if the Fastrax parts for the TC3 sold by CML distribution in England is the same parts as Megatech sells/ produces?

Or how about milling larger holes in the can, would that ruin the motor or making it illegal?

-BTW: DHI stands for Dansk(Danish) Hobby Import
Those holes are the shape they are for a reason. That would alter the magnetic field and could really screw up your motor.

I know that is the theory, but has anyone tried it?

You could post the question to Jim Dieter on Tech Talk. He has a thread he responds to at Trinity.

I can't imagine he hasn't tried just about everything with a motor.


Online shops in the US:

www.stormerhobbies.com

www.speedtechrc.com

www.kthobbies.com

There are others


edit: Woops! How embarrasing

Default Caster and Kick Up

I've seen setups with a 4deg caster block with 0 deg kick up and 2 deg caster block and 2 deg kick up? What is the difference and advantage because both end up with 4deg total caster..

4 deg with 2 deg of kickup is supposed to handle a bumpier surface better. On a smooth track, there shouldn't be much difference.

That is a good idea, ever try building a computer w/o the transfer compound?

Not totally true...

0 degree kickup will smooth the car out on turn-in and through the corner. Weight also transfers to the front faster. It is better to use 0 degree kick up to smooth the car out on high traction surfaces.

2 degree kickup is the kit setting because it works best in most conditions. It will cause the car to turn into the corner more and will reduce steering on turn exit.

When calculating total caster take into account kick-up angle and caster block angle. More total caster will cause the sedan to steer into the corner more and reduce steering on turn exit.

For example, using kit and optional settings:

Most steering into the turn and least off: 2 kickup + 4 caster block

Least steering into the turn and most off: 0 kickup + 0 caster block

Mix different kickup and caster block angles to get desired handling characteristics in between extremes.

Will the NTC3 bumper fit the TC3 without any major modifications?
I am thinking about the lower part, foam bumper and the top brace.

If so, will the body posts from the NTC3 have the same position as the original TC3? It looks to me like the NTC3 has the body posts further apart.

Thanks, Mike. I actually use a little negative kickup. It seems to really make the front tires dig in more in tight turns

Default Ride Height and Tweak

Thanks Mike for the explanation on Caster and Kickup.

Another thing on ride height and tweak. My car seems to be heavy on the LEFT (battery side) due to the weight of the batteries. Is that what you call tweaked? Anyway, I've been reading about how to adjust tweak and it calls for adjusting the shock collars. Now, if I do that, the ride height changes at the same time and will not be even acroos 4 corners. How do I tackle this problem?

Default Setting Tweak

Having more weight on the battery side of the car is weight bias and not tweak. Weight bias isn't great to have but tweak is worse. Tweak will make your car noticably turn better either left or right.

Tweak is a diagonal problem in the chassis. For example, if your left rear wheel is lighter then your right rear wheel, then right front wheel will also be lighter then your left front wheel. You correct tweak by adjusting the shock collars diagonally. In this example, you would tighten the left rear and right front shock collars equally. This will fix tweak without jacking the ride height from left to right.
