Thanks alot for the kind words guys.

Jeff, the front arms are delrin.

Adrian, i am on the fence about the floating servo mount. I agree with concept and i like it. I am questioning if it is needed on a foam tire car or not. Sedans run rubber tire and have been reliant on chassis flex as a tuning option and solid bracing of the servo can really hinder symetrical flex. On these pan cars, they are so rigid and this chassis is probably the most rigid i have made to date, i feel it may just be gimic in my case and added weight. I am waiting to test the car to see if it could help or make an improvement. If it can, i would do it.

By the way, i am going to try to run without a servo saver and see how it goes. I want to try to get away from it if its possible. If not, im going to add the cutout for it.

Looking very nice

How will the angled rear side links effect the car compared to running them straight? Nothing wrong with using tape if someone is concerned with the servo mounts causing an imbalance in flex, why add extra weight and compromise in the design.

Not sure about the angled links. They will be narrower and they look cool. From a geometry standpoint I cant see how they could change the pods rotation or travel. As the pod rolls each link pulls on the outboard pod pivot ball equally until the assembly binds. This is a non issue as the bind occurs far past the point where the chassis and or side springs would bottom out. Someone mentioned rear steer but I cant see how that comes into play at all....unless you run one link...lol!

I am sorry I brought up the center mount servo mount. Jason is 100% correct the chassis is so stiff the servo torque will have ZERO effect. I just thought it could be a cool gimmick to lure in more sedan guys

Yeah, Angled links wont change how the pod pivots.The spacing between the pivots on the link is what will change that. I angled them inwards to narrow the chassis and also to increase the bracing effect that the links have to keep the pod straight. The pod is connected to a center pivot ball and when you try to push the pod against the links, It rotates on an arc. Angling them helps reduce the flex in the pod that causes irratic rear steer in high grip situations.

Thoughts on incorporating the servo saver into the front bell crank? I will probably want to run a SS just because I don't like replacing plastic gears in the servos after a real hard hit.

I need a 12th scaler for the pavement nats, will this car possibly be available a month or so before the race?

Same here. I have known Jason and ran BMI stuff for years. In the local WGT class I regularly get beaten by 2 year old Copperhead 10's. BMI cars flat out WORK.

Its a real shame that some of the former team drivers jumped ship for rides that they thought were safer bets for big races. Not knocking them...just sayin! I feel the C12 and C10 were/are competitive with and are often superior to anything else out there and it would be cool to have some top level drivers loyal to BMI and committed to showing what the cars can do.

Its awesome that this car is using conventional links but I am really excited about running this car with the optional flex links. I really believe in that suspension system.

Why are your CF pieces grayish in color and has matte finish as compared to other CF, black and glossy?

I like the grayish and matte finish better.

I also ran a DB12RR for a long time. But I will say while I was initially thrilled with it, the limitations on setups for the flex plate side suspension became a huge hurdle to tuning.

You could not get the rear of the car with any of the available flex plates soft enough to really conserve corner speed in stock classes and be efficient. The car worked great in the faster classes, but in stock it was always too stiff. Going to a normal link car dropped my stock lap times by over 3/4 of a second a lap from the old BMI. So this is a great direction I think Jason is going.

Going to the traditional (and AE at that) side links and center pivot makes me real happy. My current V-Dezign cars use the same links/center pivot/springs meaning I can run them side by side with lots of the consumable parts being interchangeable.

Its the same top quality quasi iso-tropic CF as in other cars. Jason just gets it with a matte finish. I agree it looks different/cool

I think the new car is going to make just about everyone happy.

BTW, I too always liked really soft side spring rates. The C12 had longer, straight flex plates than the DB10RR and with narrow .060" G10 or 1.2mm carbon flex plates you could get the rear very soft and almost completely dead on center...as if you were running soft side springs just touching with no preload.

Yea I am also looking forward to the link spring combo but in high traction situations those flex plates are money! They are faster than the link and spring combo in higher grip.

Everyone will have the option of running either.
