Default Bad Luck or Problem?

A while back I asked about the steering posts that went all the way up to the top deck. The problem was the the holes seemed to have been growing larger. The recommendation I received from everyone was to either CA the inside of the holes or use plumbers tape to take up the slack.

Well, I did both.

When I last raced last week I was running in a a heat and as I came around a sweeping right hander someone with a TC4 drifted wide and put me into the wall. I kept racing but noticed that the car was now all over the place. I figured I had tweaked or broken something.

When I took the car off the track I noticed the following:

- I had broken both the left and right 4 deg hubs
- I had broken both the left and right a-arms
- The front sway bar had come loose from the grub screws and the top mount had chewed into the plastic CVDs.
- The car now has a pronounced left to right tweak.

Since the track I race at does not carry schumacher parts [I have even offered to purchase $100 worth of parts] I was done for the night.

The question is this: Did I break so many items because the top post where too tight? Or did I go into the wall just right and it was bad luck? I just did not expect to break so many parts from one crash.

Also, while this is bad, to save some money and have some emergency parts on hand, the arms that had breaks did not crack all the way through, so I am going to CA them -- has anyone else jury rigged the arms?

One thing you should think about is those parts may have had hairline cracks in them already but weren't bad enough to really effect the car. Then one light hit could finish the part off. You hear people all the time talk about a fragile car and "I just touched the wall" but if there's already a week point there from a previous crash that the car didn't break, a slight hit could finish them off. I don't think you would have broke that many parts just because the steering post were tight in the chassis.

Please post an MI-2 carpet set-up, my son is gonna run his this Sat. for the first time, got some idea's already just need a little more input.

Nomaak, we run a mission at the Wood that does pretty well, I can give you that set-up. My 11 year old ran 26 lap's at the Wood last time out and made the A. Probably just run the mission at TRF, and his new MI-2 at Rosewood. Lmk, later............

Jon Kerr: Thanks for the reply -- I guess I was just surprised. This is only my second TC. My last TC was an Axis 2 and in all my past racing I never saw so many parts broken all at once so I wanted to make sure I was not something wrong.


Another Question: To fix the tweak do I basically take everything off the chassis and use the "stand the car on its shock posts" method in the manual or is there a better way?

HENRYJ:

I have started with the carpet setups here:
http://www.racing-cars.com/usa/searc...e1=prodvalue14


And here:
http://www.gearchart.com/index.cfm

Search on Schumacher Mi2, Drivers = ALL and Carpet

I started with Paul Wynns Snowbirds Carpet setup and have been refining the setup from their. Then you will have to adjust to driver style and track conditions.

I have been using XRay Springs but I understand that Schumacher now has a new Pro-Touring Spring Set.

I have been racing with the stock chassis and 40wt oil F/R with either Jaco Dbl Pink/Orange Front and Dbl Pink Rear or Parma Cyan Front and Magenta Rear. I found the purples made me traction roll at the tracks that I raced. I have also eliminted the front and rear riser plates.


Good Luck, hope this helps -- I know others on the board can help you much more than I

As far as tweak goes, I'm pretty anal about checking tweak. I'll do the shock tower trick with everything on the car, tire included. That'll make sure the chassis is flat. Then check your droop to make sure it's where you want it and that it's even on both sides. Then I use the notch in the shock tower to lift the end of the car up and make sure both left and right tires are coming off at the same time. Use the preload on the opposite shocks to adjust it. Make sure that the flat surface you're checking this with is level. Otherwise it can be inaccurate. You can also use the MIP tweak station to check and make sure the suspension isn't tweaked. I've been know to check all three ways before I'm satisfied.

Hey Leadfoot, thank's for the info! I did'nt know Schumacher had the set-up's posted. The set-up I have in it now is close to Paul's 04 Snowbird setup. I have Asc. yellow spring's in front and copper rear, pretty much every fast car at our track is running these spring's. Track is a little bumpy and these spring's seem to help settle the car a little.
Our track has med. bite, so after we run a couple week's I will let you know how it goes. Got a 120 spur on also. Ran a 118 on his mission on carpet that worked pretty well.
Thank's again............Hank

Is this with steel dog bones?

Some steel bones I got recently were badly machined and suffered from this problem. What you need to do is take a modelling knife and just run it round round the inside edge of the the dog bone joint to create a small chamfer. The bit where it makes contact with the axle at full lock. (Hope this makes sense.)

This problem was bad enough on my car to bend a dogbone before I realised what was going on.

Hey PW, have you got a newer foam setup from the Birds one that was there a few months ago that would work with the new rear hubs? Trying to get a baseline to work off of for Brushless for Novak. See you in a week. Adrian coming too?
