Use anti-squat to keep too much traction from going to the rear, to maintain front traction when accelerating.
The question to JHARDY is wether you are loose in the corner off power, mid corner or on power?

Thankts
Thanks Kewdawg
MikeR ... seems more like on power and mid corner at the same time. Our track is pretty tight. All racer have to burp the throttle once or twice and when I do that, then is seems to loose traction. I run no brake on the ESC so it doesnt slow down much.
Please tell me what direction I need to go. Kewdawgs explaination was good, just too good for me I guess.

That means when you get on throttle the weight isn't transfering enough to the back tires to provide grip- the weight need to shift to the back of the car on power. Several things will do this for you;
1. increase your front droop- as a rule I always have slightly more in front then in back.
2. zero anti squat in back- anti squat or kick up tends to take away traction from that end of the car.
3. slightly more rear toe in (atleast 2.5)
4. firmer front shock- induces weight transfer to rear.
Make slight adjustments- radical changes will compound the problem.
Also watch to make sure the rear chassis isn't so low (ride height) that it's bottoming out when the weight is transfering to the back- not good.
Also get this great book- http://www.hobbylinc.com/htm/xxx/xxxb001.htm

If, you have to "blip" your throttle on an electric touring car, then several things could be working against you:
1- you don't have nearly enough steering or
2- you're taking the wrong line into the corners or
3- you're throttle input is not smooth and linear (none of that on / off, like a light switch, stuff) or
4- you're not letting off soon enough before going into the turns.
Give us the rest of your set-up, so we can make good suggestions for you.

Hey kewdawg I broke down and bought a Cyclone last week. I thought sure I would see you with one. Your a pretty big HPI guy over the last few years. It will compliment your Pro4 well. I might buy a Pro4 so I will have a few more spares for the Cyclone and also to have the option of having a shaft car and belt car.

I knew you were going to get one. 
I wanted one but the price was way too high! 
Maybe when it drops a bit more and they get that, "lack of a front diff" issue, worked out. It has the same suspension so it's gotta be good.

I will say the car is so easy to work on and I don't it needing really any hopups to be fast. THe Pro 4 suspension is a plus as makes getting parts even easier and Horizon Dist. carrying them is even better.

All you need is a set of Take Off 32's and you will be race ready. Your Pro4 should be fine. Traction is very high and carpet like.

hey,
i recentley picked up a pro 4 in a trade and have a on-road track opening soon. this will be my 1st venture into racing onroad besides my micro when i had a track in my back yard. i will be running on sealed ashfault. not shure how the track will be laid out but what would be a set up to start with?
