Suspension.... How about a suspension similar to the
Yokomo MR-4TC SD SSG. It has four camber link positions on the Hub, and seven on the tower for lots of options.

Default OPEN SOURCE

Making the design available as GNU (open source) style.

Let make some woden model and RTV mold it and pour the plastic in!

instead of machined aluminum cast is lighter and pretty rugged
what you guys are refering to when controling brakes ratio front to rear is called a porportioning vavle in real cars!

Lightbulb THE DAY HAS COME

Hey everyone!
I have some great news everyone my partner and I just completed our proto-type chassis.

My good friend Bob an Engineer who races with me designed the chassis. He says:"The Chassis will support two different battery configurations (3/3 split and 4/2 split). Each configuration has two placement options which give you a total of 4 different battery positions versus 3 for the standard TC3 layout. I expect the 4/2 split to provide the best overall chassis balance and the best performance”. "What I have done is rearrange the batts, motor, servo; esc and receiver to improve on two key factors in race car dynamics namely weight balance and inertial mass moments. The latest car configuration has near perfect static weight balance on all four wheels in the 4/2 battery split configuration. The inertial mass moments have also been improved over the base TC3 by some 10% in all three axis. This should help the car respond faster in the turns".


As for me I am doing the fabrication for the prototype. I will be using Mastercam and will be using the CNC Mill's and Lathes to create the parts.

In a couple weeks or so we will have pictures of the car coming to live!

Thanks for looking!

me and a couple of guys I race with ran a 4x2 batt configuration as long ago as 2000, and one of the guys ran a 3x3 on our tc3's, also something you might want to consider is that you have now changed the yaw rate fore and aft on the car....

Default Experimenter

I think this thread is great for the flow of new ideas.

Having built a prototype car for "fun" - I can say that fit and finish will really determine the speed and functionality of the car. We all take for granted that today's race worthy cars (X-Ray, XXX-S, Mission, TC3, etc) are all CNC machined with ultra precision. In an RC car even being out of alignment a hundreth of an Inch can mean a lot of friction and thus poor performance.

This is especially true on "mesh" parts such as the 90 degree gears in the TC3 gearboxes. Someone in a thread was talking about making some delrin versions - that might be a go for this project.

Also - using good quality bearings makes a huge difference! I was considering using needle bearings instead of std ball bearings because they are so smooth and have very little compression play (although do not cater for side forces).

(BTW my fun car was a direct drive/single belt 4wd pan car had great accelleration but made too many trade-offs for handling)

Default Hey

Thanks you guys for all your ideas on what you would like to be put on the car..As it stands where using all the TC3 components drive train, suspension, and motor mounts..
For the future , our next chassis will other manufactures components!

Anyone can join and share there ideas...

Thanks everyone for your intrest

I have been testing my prototype shaftdrive.
I used tamiya suspension.
Yokomo drive tran (easier to maintain).
3 mm lower deck
2.5 mm upper deck
Aluminum bulkhead like tamiya 414m
I call it Tamiya Ev0 4
