Have you checked front and rear track width ? 1 mm off can have big impact on handling.

One thing you guys may want to look at is the exp. on your radio. I encountered a similar problem (spinning out ) when I switched from the 710 to the 720 . my radio exp. was way too far and was locking one tire up going into a turn. it may not lock up just rolling it turned,but with a 25mph turn forcing the tire inboard more it will touch the knuckle. Hope this helps

I think I have found the problem......seems that my front was too narrow and my dog bones are binding. The suspension arms would not move up like they should limiting the suspension travel......and then when you turn the wheel with the suspension are in the up position it would totaly lock the wheel.... Thanks guys for all the help guys...

ChuckNizzle, I will listen next time you tell me something.....uhmmmm...

hi guys:

Almost every day I drive my 720 I broke the exaust spring (the spring on the tip pf the tuned pipe). I broke more than 10 springs.I always mount it without being compressed, but is always break. Any hints on the root couse of this problem?

regards

Eduardo

Check that your pipe is not protruding too much. The stinger should be really close or right along the width of the car.

I hope you didn't throw away the broken exhaust springs. You can "revive" it by unlooping/straightening one of the coils. When you make the bend, make sure it is not a sharp bend like an "L" but more like a "U".

The stinger should not be past the tires. That way if you hit something it does not break.

Killa G, it was like 196......and I didn't sand anything off of the dogbone. I'm going to set it up at 200mm in the rear and 198 in the front. That should make a world of difference...

Nizzles you also need to make the other changes we were talking about this weekend... you also need to get rid of the other tires you were running, and get some JACOS...!!!

My 720 ran good this weekend at 301 raceway I qualified 2nd 3sec back from TQ.. Had some problems in the main

196?

Follow the stock set-up to the T and with the exception of a push on-throttle, the set-up is a good starting point for most tracks.

Too narrow of a track width in front with dogbones is defintley bad,, I think even 198 is pushing it... look it over close, make sure there is no binding, you can also run Universals in front, but then you run into the fragile uni problem....
To fight the on power push, you can run one shore softer in front than in the rear, this also has the added benefit of giving more even tire wear...

198 should be Ok with cvd's or dog bones. When I run dog bones I run 198 and it is fine. You just have to make sure that there is no binding. Lift the arms up all the way and if there is no binding then it is OK. If you want to narrow more than 198 then you must shave the ends of the dog bones.

If you're running cvd's up front, always have an extra pack on hand... Also, you may want to get the front lola bumper plate and the extra wide front foam bumper pad... Your front end will almost be bullet proof then. In the year that I've had the car, I've only had the replace a couple of cvd's and the front belt... Other then that, the car is rock solid!!! Remember though that anything can happen at the track so always have extra spur gears, arms front and rear on hand... .02
