Yes, of course some parts are using from current cars, but the suspension are fully original - there are no one part from any other car.

Of course, when the producing started, the car will looks better and all parts will be original.

There will be gearhousing from CNC Aluminium instead geaboxes from PRO4, lower upper deck, lower steering, etc. That car is just to test suspesion - we see, that it works really really good.

Will these dampers also work on bumpy outdoor tracks...
Dampers are not that critical on a carpet track where I assume this car has been tested. But it will be interesting to see it, dampers are so underdeveloped in all classes of rc cars.

it works really good )) both it has different forward-back viscosity.

that sounds heavy would rather see plastic

It you tighten molded gearboxes too much, it will bind the gears. CNCing them will make them perfect so you can tighten them all the way.

metal threaded inserts in the plastic work well too. And with shaft car gear boxes you never want to tighten them all the way. Bearings are bound to bind up

Thats funny but im with Jo90 on this one, nice to see someone developing something different.

And yes, in stock you need all the sharp response you can get from the transmissions "on power loading" and shaft driven cars give that nicely

But if they were CNC aluminum you could tighten the snot out of them, and they wouldn't bind up. Thay way the diffs are sealed.

not true, I had aluminum diff cases on my tc4 and if you overtighten them they bind the bearings

I think aluminum diff housing will be fine. It'll make up the lost weight for not having traditional coil-over dampers and be eye candy at the same time. Car's gotta meet weight restrictions, and I bet it wouldn't if it was all plastic/cf with the type of suspension they are designing. Looking at that pic there are like 10 lead weights in the front of that thing, alloy diff housings would help. I'd rather not have to put $50 in quarters in my car to make weight, youknowwhatimsayin'?

Looks cool, can't wait to see how the damping system works!

So from looking at all the pictures and posts, I basically gather that this is a shaft drive 4WD pan car with gear reduction and independent suspension with 1/12th style grease/friction dampers. There's a custom gearbox that mounts directly to the motor shaft and does the 90deg with bevel gears to a shaft where a standard pinion mounts to drive a standard spur like a traditional shaft car. Thats a nice idea for a good "CARPET" CAR! Once is gets lumpy and bumpy outdoors, its back to the traditional shocks and suspension. Still good though, has Marty L. Petersen seen this yet?

MMM OK,,,

TRF415boy

100% wrong on both assumptions. 1st it's not a bevel gear that does the 90° transfer, 2nd he wouldn't be patenting the shocks if they were the same thing as used in 12th scale. I know the designer, he's a very talented engineer, and although I don't know everything that's going on with that car, I can tell you we're in for a few innovations there.

Okay then is he using something like a flex drive similar to a Dremel tool for the 90? Is the dampening separate of the springs? If so, is he using leaf springs?
