Very nice... The thing must be nuts on the track now.
If you could do me a favor and show some close up pictures on how you mounted that wing. I've been wanting to do that and have some ideas but if you could share some insight, that would be great.
Also, if you want to shave a little more weight off the truck, I've seen some, what seem to be, very nice carbon chassis plates that are quite a bit lighter than stock. Since you seem to race and not bash the truck, I think you wont have a bad effect from the slight decrease in durability.
This is the website of the guys that make em:
