The motor pod itself runs on a seperate pivot that provides the left to right movement, independantly of the forward to aft. There are holes down the side of the links that are used to either stiffen or soften the forward to aft movement whilst differant thickness damper syrup controls the left to right. I remember the 12V coming out many years ago, and tried to work out how the rear end worked, believe me, it's much easier to understand once you have one in your hands! Although I don't have a BMI 12th car, I do have the GT10 which sorks the same way. It's a great car that works really well. I'll try to take some pics of the rear end of the 12V and you'll see how it works, very neat!! Cheers, Chris.
PS, I have just looked through the pics on rc50.com from Vegas, and there is a Corally chassis on there which is EXACTLY like the one I am getting made up at the mo, GUTTED!!
I dont doubt the 12V is differnet, but from your explantion above... I dont quite agree. You are saying that the 12V front and back pivot motion is controlled only by the side plates? Wouldnt the center shock and central pivot be handling that? On the BMI the front and back is only handled by the central pivot and the center shock. the side plates handle essentially the lateral alignment of the rear plate and side to side rotation. Which from looking at diagrams of the 12V rear end, look strikingly similar.
Edit: Just realized that the 12V doesnt run a central shock... hmm so yeh I guess I dont know how the 12V works... voodoo maybe?
Just looked through those pics on RC50. I didnt see what I was looking for (the Serpent LiPo chassis), but saw some pics of an old 12V there. Lots of R5's a few BMI's it looks like, and a handful of Corallys. Nothing real amazing except that Slapmaster embedded T Bar. I will be very curious how that car runs. That and the one off car with the link steering and custom rear end.
