Wings and Spoilers
Recently I did a science project to figure out what wing on my touring car had the best lap times. I learned that from the varibles that the 200mm wing gave my tc3 the best rear traction and lap times. I also tested the stock wing, the after market 190 and 200 millimeter rear wings by protofrom and no wing. Hear are my results...
Wing Average lap time
200mm 10.90
190mm (stock) 11.67
190mm 11.56
none 11.96

seems pretty normal results 
but as the wing becomes more of an higher angle itll might help out in downforce but when it get too much itll just create drag (the air resistance)

you should also test the differences of a forwrd and rear mounted wing. So, move the wing foward and backward on the mount and see if that thlps out at all. You may also want to try some stabilizers along the top and rear window of the body. those being paralell lexan strips down the center of the body to keep the car going straight...while it's going straight...
cool project though.

One thing i notice doing a project like that, is you drive a different line each lap. Also you accelerate and decellerate at different points. You would have to do the same thing at the same exact time at the same speed to really get the correct results.
But good idea for a project. Maybe do something else r/c orriented.

Later for fun I put new tires and moter on and left the 200mm wing on and broke my 10.2 second record. I ran a 9.66 second lap.

Xenon type A/B straight High downforce/less corner rotation
Yokomo GW3.1 straight
Xenon Type A/B curved
Yokmo GW3.1 curved
Flap Type-RW
Flap Type-R/Xenon type C/D (curved lump)
Xenon type C/D (square lump)
may i know which wing will be suite for carpet used? which length of the wing will suite for carpet? 190mm, 185mm, or 175mm? thanks

Dude...there is no way an additional 1cm of Lexan wing kept you from crashing compared to other wings.
What you just experienced was the Placebo effect, in which your mind said that the 200mm wing should be more stable and thus you subconciously drove better.
Besides that, at the speeds our cars are traveling compared to their size, the aerodynamics involved are questionable at best.
As of now, you're crossing over into the Voodoo and snakeoil side of R/C touring, a place where people SWEAR up and down that they can "feel the difference" between a Mazda 6 and a Nemesis.

Hey soviet, probably is a placebo (although i have my doubts 
)... I'm sure my F-430 body goes better with the spoiler than without.... 
at lest you have more drag... so Karpet, that's why you're not crashing too much with the wing, you have to be harder on your brakes!!!

ROAR Legal Wing
I was kind of surprised how small your wing has to be to pass ROAR technical inspection. It is considerably smaller than the "stock" wing most people use.
Also the no part of the wing can be above the roof line.

Soviet, I worked with an aerospace engineer at one time and brought up the theory that some in the RC community have expressed regarding aero having minimal effects on a scale this small.
His response was: 'just the fact that the scale is smaller does not change the way that aero forces act on an object. Aerodynamic forces quadruple everytime air speed is doubled, this should be an indication of what kinds of effects that will be 'felt' with different shapes used on these cars. Don't forget that as the physical size of the cars are scaled down, the size of the molecules of air do not change size...'
