protoform alfa 2.0
You couldn't make it today to Poway I guess. Mark and I had some good racing in the 19 turn class practicing for Hitec. It was so hot out there. Track temps were over 145F. 
But think I've got a strapped setup for Hitec.

how does the the protoform alfa 2.0 compare to the losi alfa?

I just got my Alfa Romeo 2.0 in the mail and have gotten it all prepped for painting. I need to set up the air brush now. But I was wondering how adjusting the rear wing forward or backward made a difference. Will one of the positions be more aero dynamic than another so it will have more top end and less down force or somethng like that? Thanks for any input.

The tuning vanes on both the Losi and Protoform Alfas should help to increase rear downforce and lessen drag slightly at high speeds. The faster the speed the more turbluent the air coming off the roof section. What the vanes do is to lessen the amount of sideways movement across the wing. The air is smoothed out and channelled in the fastest possible path across the wing. This helps to increase the Bernoulli effect across the wing's profile and lessen the flow separation over the rear of the shell.

the easiest way to tell the to apart is to look at the front end, the lois's lower front vents are broke up into sections and the protoform is a large single vent. , also the losi is way more radical in the back half of the car , the 2.0 is more conservitive.

With a saloon car's rear wing you have to cope with the flow being distrubed over the roof section. To position the wing in the most efficient position you want it to be as far back and as high as possible, removing it as far as possible from the effects of the roof section. That is the reasoning behind the really high wing supports on the Protoform DTM Astra. Normally (At least under BRCA rules) the hight and rear overhang of the wing is restricted; it must be no higher than the top of the roof and overhang no more than 10mm over the bootlid.

So basically what you're saying is to run the wing in the farthest back position? I'm a little confused here, mabey it's just because I'm tired right now so I can't make sense of it .

Wow! My Alfa 2.0 is the best handling body ever. I love it, although I don't really like how the front end looks, but its not too bad. This thing is great, and it holds up great. The last two bodies I had were both HPI's, and HPI bodies suck. They look sweet, but they're thicker, so they crack more, and they also have such defined detail lines that they crack on the lines. My alfa 2.0 doesn't have any damage on it, and that doesn't mean that I didn't hit anything, one time on the first night I used the body I got wedged up on the pipes and shot out of the track into the driver's stand, but no damage there either 
. So basically what I'm trying to say is that this is the best body Protoform has ever made .

Punisher- What colors did you use to paint your alfa 2.1? I really like that paint job.

Alex Lopez (XRay factory team driver) was running an Alfa body at the FSEARA race this weekend at MDI.
