i see.. but bro, you mentioned you had one run with the cutout winglet and it improves handling.

So i wanted to know if it adds/reduce downforce? and was it with the Tamiya wing or 3racing wing? coz before I left, i think it was the 3racing wing u had on your car.

In relation to the spoiler that enhances the handling, not a single car has a spoiler before the rear wheel.

The "uncut" winglet actually makes the car planted during the in-field, but on the extreme high speed straights, it will suffer. It's not so much of the downforce, but more of the channelling the aerodynamics from front to back undisturbed, and as and when the spoiler needs to do its part, it will have have do it. I'm not sure if this theory is right, and I'm not so much of a theory person. I'm trying to make it work for all. Also in reference, the F103's range of bodies were never with the winglets. Could be due to the replications of the real thing, or purely the cost-cutting factor of not producing replica of the real thing.... Whatever it is, I'm determined to make it work.

I was on the 3Racing when I went for my run.

Surface is medium-grip outdoor asphalt. Haven't used any traction compound.

Over the weekend I tried a different circuit (Whalan Reserve) and the B's shone there as well. Much warmer day and a grippier higher speed circuit. Some photos can be found here.

Some of the push/understeer I'd been having seems to have been improved by loosening the diff slightly, so it runs quite smooth, with only minimal slip. The friction plate nut is set to around 8mm.

Does anybody know a webshop that has the F104 rims on stock and that ships to Europe? At many webshops they are out of stock...

Greetings,
Marcel.

The front and rear are on 4mm. The front is lowered because of the spring I used that's a little shorter than the Tamiya ones.

Hope it helps!

DO the kawada need a bush? or is there a bearing that will fit?

The hole in the centre is good for 1/12 pan car's drive shaft but not the Tamiya ones. You will need a bushing.

Alternatively, you can go the cheaper way by reaming the hole big enough for the 1280 bearing to fit snugly into the centre. It will work just as well. However, do it with caution and don't over-enlarge the hole till the bearing is loosely fitted.
