Has anyone used 1mm shims under the center and side link pivot balls to adjust the motor plate to the same level as the chassis.Scratching my head as to why it is not 3mm carbon fibre like the chassis.???

The part that matters, the upper side of the chassis and rear pod plate are level already. It is the bottom side that is different. If you shim it you would have to shim under the center pivot balls, under the side link pivot balls, and the motor pod plates. It is just a lot easier to just remember to set your rear ride height .5mm higher in the rear to keep the chassis level.

Try a 1mm shim under all the balls for the rear links

I bought one of these cars less than a week ago to have a go at the F1 class and broke a steering upright during an altercation with a wall...

I have been searching for the last three nights for a place that stocks the steering uprights but the one place I found that appears to have them doesn't post to Australia.

Can anyone give me some advice on where I can get some parts for this car that will post to Australia? Even the Speed Passion site has it listed as out of stock. It shouldn't be this hard to find one part and if it's going to be then I may as well cut my losses early.

Thanks.

Hi all,

I managed to make my understeer a little less bad but was still a mile off the pace. (Finished 33rd from a field of 70)
I had mid / bottom B main pace by the end of the weekend but still couldn't get the thing to turn.!

I have recently ordered the Tamiya F104 front end as this may provide more options, (Spares for Speed Passion are few and far between).
Also, the front end seems overly complicated on the original kit!

I managed to get some uprights from TSR Products in America I think it is, they are showing as in stock. If you are really struggling, let me know as I have a spare packet that I could post to you.

These are probably surplus to requirements now as I am going Tamiya front end.

I am also planning to change the battery to a transverse layout to get more weight by the pivot of the pod, angling the centre shock more and moving the links out / up to get more front bite.

Any other ideas I could try?

Thanks
Darren

F1 RC Lab also have a stock of parts and may be worth a try?

I also have some CRC uprights from the CRC WTF car and these appear to be a direct fit / replacement. You may find these easier to locate.

Parts in Australia. I have been searched this site but expensive ship to EU.

In tamiya parts You could wider front end than 190.
If You can't turn in try harder all springs and thicker central dumper.

Hi,

I tried stiffer front springs and a stiffer centre spring.
I also tried playing with the incline angle of the centre shock as this gives more steering in 12th pan cars.

I went from 10000 to 30000 damper lube and back again but little difference.

I finally tried some anti dive.....This allowed me to carry more corner speed but I still lacked overall steering

I also tested both 5 and 10 set caster to try to gain more on entry and more mid and exit steering. Again, not a.huge change.

I think most of my problem was the ride tyres.....The fronts are very hard.
But.....it was controlled tyres so others have found something to give more steering.

I think with more time and testing I could have made the A or B main on driving......but the car was 'box fresh' when I arrived and didn't turn a wheel until practice.

Not ideal preparation when i have never driven formula class before.
Hahaha

Been in touch with Walter RC mate, they've been waiting over two months for the parts as well so couldn't help.

Cheers for the offer of posting parts Lee, luckily for me one of the club members felt my pain and is throwing me an old chassis he has laying around which has the part I need.

Do you mind posting up the part numbers I need to do the Tamiya front end conversion though? I saw a post earlier in this thread but couldn't distinguish what was actually needed and what parts were optional, I'm still pretty new to this stuff.

Thanks for the help all.

Jan Rhateisky in own xray makes tires mounted on a drilling machine beeing sanded with the sandpaper. It is makes tires softer. I just have read this tip in xray x1 group on FB.

I tried sanding the tyres but perhaps didn't sand them enough.
I will try sanding them some more.

The parts required to do tamiya f104 front conversion are;
50395 front knuckles
51381 front arms
And then a screw set.....I managed to get a f104 front end screw set complete off eBay.

I have also ordered the reinforced uprights as backup.
54154

I haven't fitted it yet but have been advised it's a straight fit with no modifications required.

As I said....The crc uprights and axles are a direct replacement for the speed passion parts.

Thanks

Battery place forward gives more steering.
