Need help !!!

[Panic]

So...after a frustrating and disappointing race day with my predx11 i need yr help. I broke the suspension pivot and the body of the screw is left inside the aluminum front cross brace . Any idea how to remove it? Cross brace is brand new....

Bad day for me ...had my small problems in the past with my pred but not so many in a day. 1st qualifier and I break the rocker pivot ( never had broken almost 8 months now) so i change the whole thing, used old cross brace etc etc, 2nd qualifier and i break a ball joint and 3rrrddd qualifier I break the chassis and the same time the spur strips ...

I did this last year...

Few Questions, could your car bottom out fully? Was it screwed in nice and tight?

I tried many things to get mine out, pliers, screwing another rocker pivot in etc etc, none of which worked..

I ended up drilling it out and then putting a helicoil into it...

I bought a new X brace and now use that but my dad runs the old fixed one on his X10 no problems..

Hope this helps,

Tom

Yes everything was nice and tight, i always doublecheck before each heat just to make sure. The only thing that was holding the car from splitting in half was that little silver brace that screws into the rear shock tower.When i removed that, the car fall apart in 2 pieces . It happened in a big triple jump when i landed right on the top of the 3rd , the surface was hard pack.
As much as i like the way it drives in smooth flat sections of the track the more i hate it when it comes to jumping.

remove the x brace and you should be able to get hold of the pivot from behind (just about) i have boiled all the ball joints + front and rear hubs for 20 mins then drop them straight into a penatrating oil like wd40/gt85 and leave them over night. this destresses and softens the plastic and makes it far stronger.

order a plastic chassis as a replacment. they have extra bracing and are thickened up in the break areas that were found in the carbon one.

as for jumping, do you have the kit wing on ??? i use a Hb wide wing and trim the guerney down untill the car jumps just nose down. this has really added stability to the car. i also run the car in a stick lipo format as this makes it jump flatter as well and gives more mid corner pivot

try kevs pushrod mod as it also increases front droop and the rear droop mod as both of these help the car across the bumps and landing off the jumps

and about breaking rocker posts.
To prevent problems in the future, i just dremeled a groove in the bottom of the rocker post, so that, if it breaks another time, I can dissemble the cross brace and just use a screwdriver into that dremeled groove to unscrew the left in piece from underneath.

I'll post a picture of this later on.

(I used to do that with all the ball ends on all of my cars)

Panic- were you using the hollow posts or the new soiid posts?

Nathan - any other parts you boil? Would you boil the plastic chassis?

Lowie could you please post some pics of the mod you have that allows you to remove broken rocker pivots screws from the cross brace?

Thanks
