And still has some time left on it
I have noticed the hpi CAMARO is a bit thicker now and will probley
Last long as well and it seems to be a bit shorter and lower then the j71
Have any of you tried these bodies back to back and seen any
Change in lap times or in the way the car reacts to body change
With a good chassie setup
I've done this precise test at the Leisure Hours Raceway in Joliet, IL, home of the 2012 ROAR paved on-road championship in August that I plan on running. This track has a 225' straight away and with the right gearing you get some pretty good speed up for VTA. I was testing 3 bodies actually, the HPI 68 Camaro, the Protoform J71 and the McAllister 69 Mustang. I'm not sure what it is about the Camaro, but I don't like it as much as the other two. It might be my own personal bias, but it just feels less stable to me. I think it may have something to do with keeping the scale appearance to the windshield so the angle is pretty steep. Both the McAllister and Protoform bodies are smoother, more rounded with softer angles to the windshield which I think stabilizes the car and sends more downforce toward the rear. My lap times were the most consistent with the McAllister but I hit my best lap time with the J71. We're talking a 22.0 lap for the J71 vs. a 22.1 for the Mustang. I've been running the McAllister because I like it's very neutral feel better than the rest, but I've run all three bodies on shorter parking lot tracks and really can't tell any difference. Of course, these are just my opinions and your results may vary.
