I am just wondering if I possibly have a problem with my Schumacher Mission S1, as I am getting some strange handling problems..
Initially, I bought the car in as-new condition but second hand and built by the previous owner. It had some minor problems when it was built, like the owner had rushed the build or something. I have fixed up these problems now anyway.
Now the handling of the car is all over the place, mainly it is very very taily and has massive snap oversteer.
I thought it was the surface I was racing on, but it was driveable at the start of the day, but by the end, it would spin out as I turned into any fast corners, slide was uncontrollable and sudden. Surface was a concrete tennis court, i was running yellow springs on the front and rear, no swaybars, with 24mm CS27's all round. Front was running std ball diff, no spool or one way. Diffs were a little crunchy..
The tires i was running were pretty well stuffed, so I endulged in a new set of CS22's, rebuilt the front and rear diffs, and headed back out to the track. This track is a faster track, with an older surface that usually provides plenty of grip for the other guys.
This was also very taily and spinning easier, with the same yellow springs front and rear. Remember, I had NEW CS22's front and rear.
Meet was rained out, so headed home.
Next day, swapped the front springs for harder Red springs, appeared to help the problem somewhat, but it would still suddenly spin, especially turning around a left hand turn. If i stayed into the power, it would spin into a donut, pivoting on the front left wheel asif that wheel was locked from turning. It would do this with the body shell on or off.
All the time i did not change the shock pistons or oil, i am not sure what either of these are setup with (oil weight, or piston holes).
Motor is a Peak Hellfire rebuildable 27t stock, nicd 1700's and gp 3300's (mmm, punchy). Problem was also occuring with previous motor, a tamiya super stock (23turn).
Weight balance could be the cause, it is probly mile out, but I dont see how that could cause it to be as far out as it is.
I will rebuild the shocks also, make sure they are configured all identically.
