Hi everyone..

As some of you already know, I just love my cooper body.... bur a 90mm setup for carpet is not easy to set.

I was wondering and playing arround with my parts for other setups, and tried to make a hybrid system! Does it work???? I DON'T KNOW YET!!!!

Here's some pics:

Rear view... The motor is at the lowest position allowed by the mount!

Upper view... Notice that the center pin of the damper is at the limit of the internal circle of the plate... I don't know how to solve this and put it at the center. I can just remove it, but I want to test with the top dual spring shock first! I can take out the screw of the RR pivot system of the T-Plate, but this would lower my rear end and decreasing the up/down suspension movement.

My preview tests at the office's carpet said it does work, but I'll try at our track this week.

Tell me what do you think about it, and how to make it better....

Some little details:

- The body must be mounted in a different way, putting first the side clips (a complex manouver, but very quick) and stretching the front clip (making the front part of the body flex a little).

- The motor is almost touching the screws of the dampers. I don't think I use more than 12/54 gearing (.64 atomic pitch)

- I'm using the 94mm tri-damper system plate "sandwiched" by the center 90mm carbon plate and the PCB cover. The cover is a litle curved, pulled by the strenght of the screws, but I don't think I'll have any problems with that.

I think this is a good idea for PN to develop an extra tri-damper plate for using the 90mm bodys without making all this "ugly adaptations" tha I did...

Please tell me what do you guys think, and how can I make it better!

since the shocks are triangulated you dont really need a center shock, you should be able to go lighter on the springs. i have been running my F1 like this for months and also my LM car
