Wow that one is really cool

I finished building my Icon today. All ready to go for the first shake down tomorrow.

I omitted the two carbon wing mounts and bolted 10mm stand-offs to the wing mount holes in the main chassis. Then I bolted the U4710 wing mounts to the top of the stand-offs. I had to modify the wing slightly as the holes are a bit too far apart to line up with the holes in the main chassis. A leather punch works remarkably well to move the holes a bit. I had to add 2mm shims between the chassis and the 10mm stand-offs to get everything lined up perfectly. When you change ride height you might need to play with wing height too running your car this way.

The main element of the wing gets plenty of air the way I've got it mounted currently, I don't think the downforce of the wing is impacted much. The rear wing weighs 32 grams and I want that weight as low and close to the rear axle as possible. Tomorrow I will try the car assembled per the manual and let you know if it makes the rear grip change or if I can feel the difference of the weight hanging that far back and up high. The track layout was new yesterday, but my car currently holds the track record for F1. My car almost wants to traction roll if I really throw it into a corner hard with the low wing, so I'll know if the weight distribution change makes it traction roll almost immediately. Ultimately I'll run whatever produces the lowest lap times.

If you want to run a rear mass damper you can bolt the lower carbon wing mount underneath the stand-offs and still bolt the wing to the car the way I have. I've only run the car yesterday and today, both days with the mass damper up front. I can try moving it tomorrow to see how it drives with the mass damper in the rear as my last car only had a spot for it in the front so I couldn't try that previously.

I ran my car back to back with the wing mounted my method and the kit method and they both produced 9.55 second laps. I kept running with the wing mounted with my method and made some esc adjustments and was able to get down to a 9.35 second lap. I'll probably try the kit mounting method again to see if I can do a 9.3 with it.



Try it, see what you think.

Bent the crap out of the front posts in a race couple weeks ago so got the new heavy duty post that just came out for the car and was a diffinate improvement for the car. Front was more stable and chassis tweak stayed consistant all day today. Set tq and won a main in carpet race here. Also found these post to be about 1mm shorter and and increased my camber to a little under 3deg so gives me a little more adjustabilty for camber with 2deg strap. Haven't tried it with the 1.5 strap yet.
