I took a beatdown from an EVO IV, so you should be good to go

But if outdoors will allow six cells or a 7.4v LiPo doesn't TA just become "stock rubber" with a different body and wheels?

I ask about outside because Strictly will be racing outdoors this coming Spring/Summer, and I am looking for guidance in creating the racing program.

Kenji....I think the thinking behind that is due to the fact that most parking lot tracks are bigger then carpet tracks and people want to go faster on them and its easier to do that. So thats the idea behind the lipo 17.5 for outside from what I can see. Asphalt racing sees people run faster motor then they normally would inside in most cases the tracks allow for this to happen. Im not sure the 17.5 motor will be a big motor outside as much when alot of people run 13.5 as STOCK outside.

For your racing structure the best thing to do is run what the local guys want to run and build from there. No need to put people off right away because of someone elses rules or your own.

Rules updated 2.27.08. All rules subject to change and expansion should need arise...............


>>Note: Outdoor asphalt tracks will have the option of mandating a 13.5 brushless/19T brushed motor choice or a 17.5 with a 7.4v LiPo battery combo.<<

No. Precisely because the body and wheels are different, it will never be "stock rubber". Also remember this is the first time trying this outdoors, other than the Florida guys, so we will all find out how things work.

I know. We'll see what happens. But....the cars now are at about 20MPH and very affordable for newbie racers. The outdoor rules lend themselves to way more speed and way more money spent. As you know racers love to think the more money they can spend that they can "buy" themselves better laptimes.

Our outdoor setup will have about the same length straightaway that Underground RC has and what Harbor Hobbies has. I think the indoor rules will still apply. Also most of our people love running additional classes and outdoors those classes are GT3 and Mod Sedan.

Need some help with TA tuning for racing on carpet.

I think we've found the best gearing at this point for the track we're racing on. I know some of the things I'd like to try next with the goal being lowering laptimes, but I'm not sure which to try in what order. I do know to make changes one at a time.

For chassis tuning I'm looking at these:

springs
shock oil
droop
toe-in
shock position

Also I had a thought and need to get back to the track to try it:

changing how I use traction compound on tires

Might it be a good thing to have some or alot of push? I was thinking anything that helps keep the momentum of a TA car up in tight turns would be a good thing. A very planted car in tight turns seems like it's slow.

We are running Lipo/13.5 right now, and it is way too fast. It appears we will be going to 17.5 for next season. We would like to go to a slower motor, but suspect gearing will be a problem with a 21.5.

The fact that bodies are top heavy and the wheel's/tires have an overall different grip characteristic, make the cars look and feel different then a TC with the same motor, but with slicks and a sedan body. I tend to agree with Rob that they will never be the same...

Roll center and caster are probably even before anything you listed. Also, camber link position.

Push will be slow. Always. The car needs to roll through the corner, so actually putting a lot of steering into the car will be beneficial. You can always turn down the dual rate.
