At the SA Nationals they allow up to 205mm, I think, due to the toe in effects.
Post a picture of your car please. I was at the race as a spectator. Got the whole 200mm final on VCR. From start to stop. And restart to end. Was a good race between serpent and Mugen.

had the 720 out this weekend, short track, made of 2x4 very hard on cars
very tight and bumpy. used stock set up in practice. went to yellow springs
all around this gave the car better balance, for the bumps i added toe in the
rear and went to the spool up front. 1st qual. 5 th overall (top to 5th separated 7 sec.) 2nd ran into parked car in sweeper broke front bumper
that ended the day. this is a great car easy to drive big sweet spot in
setup

Pls post the VCR if you can.. would be good to see... the VCR will also show all the guys on this forum the track layout and how the Serpent 720 WON... also, the few rear end moments - as Mikey had a few moments there
Will try... but to help you now... It was the red Alpha with the bright yellow spoiler... the one that was all over the place
... which is setup driven, as I was trying a new setup with every qualifier.Sometimes, it is better to go with what you know rather than try funky stuff

Well... here's a new one for you:
My exhaust pipe, let's say it leaks a bit now.
Here's the story: I was helping a friend with his car. He was having issues all day and was getting a bit frustrated. His engine would not run properly; it was either overheating or not performing at all. Compression in the engine is fine, fuel is fine, leaky front bearing is a problem but not big enough to not drive the car (as long as I don't have to clean it up)... The exhaust pipe though looks like it's been through at least three world wars and two extinction level events; pretty bad. So, I offer to borrow my spare exhaust, providing I get it back in one piece. Well, it came back in one piece, but not quite in the shape in which I gave it to him. The retaining spring at the front of the exhaust broke, so the pipe dragged over the track for several laps, there were a few dents in it, and the stinger pointed downward...
So, I put it in the freezer for a night, and now it has burst on the spot were it has been dragging over the track.
Is it possible to fix this? I don't want to ask my friend for a new pipe since it wasn't new and I guess I should have known better, but I'm not really happy with the current situation either...

JB Weld if you can get it over there. Its a metalized epoxy. It works great. Ive seen guys here build reinforcements for thier stingers like they do on 1/8 offroad pipes

Shorten your front Track Width or put 710 front lower arms on. You could also go to 42s on the rear. These options will help the car to turn in.

rear lower pivot ball problem

1. The rear of the car is loose - allot of the 720 drivers experienced the same problem - track only has hairpin bends - everyone said the same thing, the back doesn't follow the front. But still the car was easier to drive then the 710.
2. The rear lower wishbone - with two pivot balls is very weak - if you toutch the rear side of the car against the track piping - it pushes the rear pivot balls further in - I started with 3 toe in at rear and the slightest toutch at the rear and I was running 3 toe out. I wanted to try thread tape over the pivot balls but i did not get a chance too.
But, just so that all of you know, the winner at the Soth African Nationals in Durban this weekend was a Serpent 720.
Really not sure why the back of this car is so loose.... any ideas? I figure its the diff oils - the standard 50000 F and 30000 R doesn't work on a hairpin track. Thinking more like 100000 in the front and 10000 or 20000 in the rear.

I refer to the pivot ball screwing in due to side impact. besides that a broken wish bone but I finished any way
