Rear wing doesn't appear to be attached to the pod

I think the center pivot is similar to the VBC f18 design which does not constrain fore/aft. If it was designed to constrain f/h then the side bearings would not be necessary (apart from holding the car altogether upon impact). In such design though, assuming its on bearings, the rear roll center would be too high, I guess.
As for IF11 - to be honest I don't see any technical innovation in it. Just a more complicated front end and a TC type of steering. Also split plate which is controversial for me. Just the same music in different tone....

Correct. A very good thing in my opinion. The two vertical rails that run under the diff hubs are part of the chassis and do not move (although they look to be adjustable). The wing on the S4 won't be part of the unsprung weight. I always hated seeing the wings on F1's tilting back and forth under acceleration/braking, bouncing, vibrating - yuk. So many awesome improvements on this car. The battery is slung lower (potentially depending on the trap door thickness - old Team Losi/Team CRC style). I love the way servo is mounted.

I love the idea and it has proven in the past with the Impact where first the rear body mount was directly pushing on the upright and later it was fixed to the chassis to give more rear traction. I will expect a huge improvement on the traction but only the 2 small bars holding the wing will be very fragile with crashes.

Actually from downforce application perspective it is better to apply the force to the unsprung mass directly as the force does not go through the center spring. In PRO10 many times you need to use harder than you would like center spring to prevent rear of the plate ground contact in high speed. The question is how large is the downforce from our Formula rear wings.
On the positive site is the fact that the serpent design significantly, by about 10%, reduces the unsprung mass (Montech rear wing is 30g) which should be beneficial for handling.

I just hope this beauty is available by the fall. The RSD conversion for the X1 will likely be the only F1 with a chance to pull me away from the Serpent.

I have it from a good source that SF4 will be available in 4;8 weeks time.

We used to run wings mounted to the rear pod years ago, with no such problem.

All details are online on the serpent website now. The kits are on their way to the distributors around the world.
