Default Spearing off on acceleration?

Hi all!
Im new to this forum and i have a question for you :P

I race 1/10th touring cars and while i was racing last night my car started spearing off to the right as i accelerated out of a corner.
Im just looking for sujestions as to where i should start looking for the problem.
It is a Xray T2'008 EU rubber spec any sujestions would be great so i dont dive in blind! lol
Its dam typical though that it was running beautifully all night and it chooses the final to start doing this lol

Are you running 2.4 ghz or am/fm??? Someone could have turned on their car/radio and was on the same frequency. Also check your servo horn. Maybe it was stripped.

Check for a bad bearing in one of the hubs, or a diff that needs to be re-built. Also check the front spool to see if one of the outdrives is broken. Is it only at full lock? One of the front tires could be rubbing on one of the lower shock mounts. Check for stripped gears in the servo (try turning it back and forth by hand).

Its not interference from other radios as it when i accelerate it pulls to one side.
The spool and diff are ok

I tested it on the straight with no steering on at all and it pulls to one side

Check your rear diff. If it's too tight it will act as a spool and your rear traction will be shot

Tweak being way out will cause that, too.

A bad wheel, tire, foam insert will also do the same thing.

Put it on a car stand and gently accelerate. If you have a bad wheel you'll see it vibrate or wobble.

Had a problem like this once and finally figured it out after two rebuilds.

The diff does seem nice and loose so thats ok.

I will have to try and check tweak (without a propper station) xP

Not propperly checked the wheels yet either but the bearings were changed a couple of weeks ago so they should be fine

Thanks for all the help guys!

check your droop in the front and rear, more likely the front. one tire is getting more traction than the other when he applies throttle.

Default xray

make sure the screw's holding the front hubs are tight , i had one back out and was rubbing on the inside of the wheel and it had the same effect

Take the tires off of the car and place it on a flat surface, if it rocks when you push down on the front and the rear it is tweaked.My best guess is that this IS your problem.
If not check that the shocks are rebounding correctly, remove them from the car and remove the spring and then compress the shock,if it does not rebound like the others that may also cause the pull to one side.
Good luck!
