TC4 with a Shorty
I was looking at the current trend in 4wd buggies running with a shorty pack opposite of the motor. I decided to try this with my TC4. Then I want to decide if I should run it in VTA or UGST. What do you guys think?

Congrats on the excellent race result. I would be lucky to make the B main this sunday. Yes I do notice that the older cars with centered motors do not need as much flex as todays cars with offset motors and batteries. Currently I am running my dinosaur racer with a 2.4mm thick chassis, and it still has lots of traction. I do not think the trend will reverse, modern cars seem to need a lot of flex.

Flexible chassis? Colin Chapman would roll over in his grave if he heard this nonsense. If a car needs a flexible chassis to work better, it's an indication that there's something wrong with the suspension. It is much better to fix the suspension than to cover up the problem with chassis flex.

I do believe that the Mi5 Evo is stiffer than the original, which was a exceptionally wet-noodle car. A friend of mine bought one (Mi5 Standard) early in the production and when I picked it up to look it over in the pits for the first time I thought it was broken in some way!

One thing that strikes me as a potential reason for the soft-chassis being a potential advantage is that for how much they weigh, touring cars run quite hard spring rates and swaybars to prevent unplesant things like the chassis dragging and traction roll.

well ok, I wouldn't want to argue about that here. anyway, just finished rebuilding shocks, re checking camber and tweak, my car is ready to race. Hope it does not rain and I hope I wont screw up.
of all the pics of cars on this page, there seems to be a lot of us using shorty packs !

In the sweltering heat ..all that can go wrong has gone wrong. I consistentky clocked slower and slower laptimes as the heat progressed. My car was oversteering and it wsd difficult to drive. I suspected the tyres were the culprit. Rides re32 preglued. My suspicions were confirmed when a racer who drove a bd7 complained of the same thing.when he changed to another set his car was drivable. And this guy is always in the a main or top of the b. Today he ended up in the c ...just like me. So his opinions do carry weight.
i ended up qualyfying second last in the c main. My main will come up soon and i changed to new tyres. Lets see if the car performs better. Well just bad luck again for me.
