After re tightening the screws, and checking all the other ball link screws, I took the car out for the 2nd race of the night. I had put a set of soft fronts on the car to try and counter the mid corner understeer, but even with the softs on, and the steering at full lock, the understeer persisted, along with with the corner exit oversteer.
Our friend with the F104 was battling with me for 2nd place, and with about 1 minute to go the car lost all drive to the rear axle. I assumed that a pinion gear had came loose, but no, the grub screw (which was also thread locked) that holds the diff assembly on to the axle had worked loose, which allowed the diff assembly to freely spin on the axle.
In the 3rd & final race of the night, saw my friend with the F104, battle for 2nd place for all but the entire race, with him in front of me, covering the turns well, so as not to leave a opening for me to try and pass. On the 2nd last lap my friend and i were quickly coming up to a back marker, which my friend passed ok, but I clipped the back marker, collecting a piece of his body shell in my front suspension which caused my car to veer off the track, until a marshal managed to pull it out and get me going again, which saw me ending up in 4th place.
I know that the back marker was just in the wrong place at the wrong time, but it was the thing that made me feel even more bad, because I was worried about damaging his body shell. All night the F1 racing for me was a bad night, and I was glad my touring car racing was a little more positive on the night.
So my thoughts about this car?
I feel that my experience with this car has been a train wreck, right from the very start of building it, and up to this point in time. This car isn't the car I was expecting it to be, it isn't a car that I believed to be an improvement over my old car.
I'm glad Beth, and others here have had great success with this car, but I have come to a point in time where I no longer want to ride this train of disaster.
If it wasn't for Beth, this car would have been buried in some landfill long before now, and I truly do appreciate Beth's, and every one here suggestions & help, but I'm so very close to just cutting my losses and looking for greener pastures elsewhere.

To get even better rear grip I designed a new upper deck:
Now I can experiment with te place where the links to the rear pod
are placed.

That's is NICE! And easier on the eyes too...doesn't look like its ready to poke your fingers like the original design!

I probably should also explain what I did to Rob's car that I had already done to mine and that was to install polished front kingpins.
When you use the alloy lower pivot balls, the roughness on the kingpins as they come from the factors isn't good enough and you can really feel them bind up under load. The front ends is now much smoother and consistent.
Made a huge difference to Robs car.
I think I know why Rob's was so unlucky on Friday , (apart from his car being cursed) is that was Friday the 13th

Which shocks did you run on the car?

I left the type 2shocks on Robs car,
Its interesting how big a difference a servo saver does make, especially the length.
When I was fixing robs car I set the servo to where I had mine, but rob was running a different servo saver (kimbrough) and was much shorter then the Tamiya one I was using, so gave very different steering angles.
From reading what Mike at Exotek has said we need a slightly longer one again and that's why they developed this part to get better steering angles, basically eliminating the mid and exit corner push.

Rob if you need to try a different saver, I can bring one up on Friday night if you are still game.
