so...im new to this on road stuff also. not sure which class i should try...1/12or touring car? is one considered easier to tune and be competitive?
also, the motor and battery topic. i wanna run 17.5 class...and i wanna run a brushless motor. what are my options in each class?
and finally, will the track be open for road course practice any day of the week?

TC rubber on the other hand is a little more expensive to start in, and a little harder to drive, but you can run 17.5 motor with a regular LiPo with no problems, plus the tires will last longer. TC's are harder to set-up and maintain, plus they hit the walls alot harder.
And I think they are going to leave the road coarse set up most nights, but I'm not for sure. I imagine at first that is what will mostly be ran.

I have to agree and disagree with Chris in that I think a TC is easier to drive than 1/12 scale IF the car is set up right, primarily because it's a little (not much) slower and it's four wheel drive. 1/12 scale being a little quicker and VERY responsive can be tough for new guys as they expect them to drive like an off road car and turn in way too early in the corners. It's all about timing and having the car set up right. The biggest mistake I see with new guys in 1/12 scale is that they have their turning radius set waaaaay too tight, making the car twitchy and too agressive. I've always set my cars up to push just a little which makes it easier to drive and if my timing is off a little I will end up blowing past a corner instead of turning in to a board. A missed corner cost you about .01-.02 seconds where a hit board can cost you 3-4 seconds if you have to be marshalled. My car usually takes about 3/4 of the lane width to turn around and most new guys want their car to be able to turn around on their pit table. All this will do is scrub off spead in the corners unless you are very, very controlled with the sterring wheel. I'm a lock to lock kinda guy so I have to build the car accordingly.
When I first started racing 1/12 scale at big races 20 years ago I always wanted to have the fastest car but soon found out that it's more about being able to run for 8 min. with as little as .02-.03 spread across all the laps. The guy that runs clean for 8 minutes will be in the top 10 no matter how slow his car is. Frequently the guys posting the fast laps of the weekend end up in the B main because of mistakes.

thanks for the information you guys. it left me with....i still dont no where to start!! haha. i think id like to stay away from foam tires. i see everywhere on here talk about shaving them, then re gearing the car, etc. that is just 1 more pain.
1 other question. ive also seen talk of traction compounds. does that apply to rubber and foam? or just foam?
ok, 1 more. where can i find a 1s lipo?

Most guys use traction compounds on both foam and rubber. The compound of choice will be Jack the Gripper which is not near as nasty as Paragon. Yea, Paragon works better, but a lot of people can't stand the smell, so most tracks are banning it. I personaly have no problems with the Paragon but that may be due to all of the dead sensory cells that have come from using it for years. I do however miss that wintergreen smell.
The only place I've seen 1s lipo's being marketed is from SMC but I've also seen some guys taking a 2s saddle pack and just splitting it in to two packs. You can check the Single Cell Hardcase Lipo thread in the Electric On Road forum for more info.

I think I would still go with the 1/12th scale, like Steve said, TC's are great when they are set up right, but it takes a little more work to get it right. And there is alot less to break on a 1/12th scale.
Personally, I turn faster lap times with my foam TC than 1/12th, but thats just me

Now to answer your question, you will want to go touring car. Let me explain... with TC rubber, once you get a setup you will not touch your car. You will not have to worry about ride height changes, truing tires, gear ratio changes. Since you would be running 17.5 lipo most likely (you can still run brushed and sub c if you want) you will not have to do anything but oil the bearings in the motor and keep the lipo charged and balanced. This all adds up to a huge amount of track time and their chance to tune the car when you want.
Now 12 scale does take a little more set up knowledge. When 12 scale is not set up correctly they are the worst to drive. They have a very quick response to input. They are fun to drive when you can drive it and they are set up. Now they do run foam tires, so you will have to adjust ride height, gear ratio, you will chunk tires. If you are just starting out in racing on a track 12 scale will be difficult.
Now Chris and Steve are correct in the amount of experience you will find at the on road track. All of us seasoned guys (some are overly seasoned...cough cough Steve) are more than happy to help a new guy out.
I know Drew, a past ROAR national champ will be at the track often. As he only lives about 6 minutes from the track. He really likes to help out on set ups. Larry is another great guy to ask questions on set up.
Traction compound works on both rubber and foam. Corally Jack the Gripper will be the stuff to use. As this is the only stuff you will be allowed to use at the track. This stuff hardly has a scent to worry about. You will also be able to buy it at the track.
You can order an SMC 1 cell pack at Glidescope. The part number is SMC4025S.
I hope this helps.

OK a small practice report.
I went to Carbondale, ILL to an indoor carpet track. Some of you know of this track. It is 2 hours away, not a bad drive. I ran 13.5 rubber and 17.5 12 scale. This was my first night on the 12 scale. I ran the new Xray XII with Jaco Lilac front and yellow rears. I also used sub C cells. Now even thought I run for Xray I will have bias. But I also try to be honest if any thing is good or bad from my opinion. With the box set up the car was very easy to drive. It had very smooth turn in with a very linear amount of mid corner steering with a slight push on corner exit under power. With a little caster change this can be eliminated. I did run the Protoform Speed 12 body. I did not try the Speed 12b that I had with me. Since I only had 1 battery pack with me I did not have time to run the second body. Overall the instructions on the Xray 12 scale was amazing for a 12 scale. The design is old but the refinement that Xray made to the design works on the track. I rolled out a 85mm that is right a 78 spur with a 47 pinion and a 45mm tire. I know a large tire, but they were new with a truing done. At this point I can not find a down side to this car or design.
Now for touring car. The car was bad when I got there. I first had to much droop. So I went to 1mm up travel on the rear droop. This helped the car, as the car was spinning off power in a turn if I gave a little to much turn in. So to much weight transfer to the front. I made a few other changes, like a larger rear sway bar and leaned the shocks in some, this all helped. The last change I made was I added 1mm to the rear camber link at the hub. This was a huge change. The car was planted on power with no more spinning out off power. I was able to turn a 10.0 lap time for my fast lap. 9.8 was a locals fast lap on the current layout. I had a blast driving the 13.5 rubber car. It was fast and stable. It was one of those days of practice when you walked off the driver stand with a big smile because it was a good day at the track.
I look forward to our new track opening up and having some fun racing and rubbing doors with you local guys.

TC will be 17.5 lipo and 13.5 lipo.
The TC5r car is a good car. You will find allot of online setup support for the car. This is a very popular car. Glidescope can also order the car for you. They are also looking at a deal where if you buy a car kit from them you get 1 free race pass and a practice day pass. Good deal if you ask me.
TC is 5 minutes, however ROAR is going 6 minutes at all the electric nationals this year. 12 scale is 8 minutes. I would like to run 6 minute TC races. I do not think we will have a problem with running races to late into the night at first.

what's everyone think of this car?
http://www.rctech.net/forum/r-c-item...tup-plate.html
looks to be in great shape from a racer in ohio. maybe some of you know him? id like to buy new, but this come with lots of spares and looks very fresh for a nice price.
