Hey fellas. I can weigh in on the Serpent chassis as Bill and I have been working together on this project from the start.
The biggest difference from the stock plate to the BCE 811 plate is craftsmanship and rigidity. Bill did a great job with not changing the overall design, but more focus on clean layout and strengthening spots that could be weak. The BCE plate has a lot more stiffness and has shown much better wear than the stock 811 plate so far.
My first race with the plate was at Motorama (with no prior testing with this new chassis). Mind you, I'm no "Pro" like Maifield, Drake, Lutz, Savoya, etc..., but I did make the B main and was in a bump spot for the majority of the race, but I just made too many mistakes. I ran the same setup as Billy, Chad Phillips, and a few others so I didn't have to stray far away from the team just from having a different chassis. That's a very positive thing as it doesn't force you to have to start over with setup. Granted, with this plate, you could probably run the plastic chassis braces as opposed to the metal ones. I have yet to try that.
Other than Motorama, I've only gotten to race one more time and was winning the main before a steering servo failed with a couple minutes to go. I can't wait to run more, but as most NE guys know... it won't stop raining!!
Thanks again, Bill, for your hard work on this. I think we have a good thing going with this chassis for the 811 and I'll try to provide more feedback once this weather breaks.
