What have some of you guys done to remedy the chatter in the front end through the corners? I tried heavier springs to no avail, using S compound tires on carpet

Default HPI F10 parts in US?

Hi,

just wondering the best place to order parts from for the Formula 10?
I am after a set of the upper front suspension arms.

Thanks

Hi Adam,

I think most of the problem stems from the metal swivel cup in the lower front arm- they pinch the shaft then suddenly release under normal driving. Delrin pivot cups are sorely needed.
For now I coat them with silicone (clean and reapply every week) and have installed Speedmerchant damper tubes with a custom rocker mount on the arm. The tubes need to be shortened a bit. Cool thing is it seems like only the HPI can run this mod and I've noticed it really helps out the bounciness the car had before...

I'm not sure but it compares to the Tamiya medium spring. I've tried some of the heavier Tamiya springs but I always end up going back to the stock spring. The heavy springs tend to cause front end push and erratic rear traction because of the added bounciness at the front end. That's with foam tires though.

Hi MikeR,

what kind of steering knuckeles do you use? Are these the HPI PArts?
And the rear wheels look like Tamiya-Style? IF yes, how did you fix them?

Thanks a lot for answering

Kind regards,

Kabus

Hi,

Yes, HPI knuckles. They allow the use of F103 rims. HPI also has rear axle adapters for F103 rear rims. These all make the F10 much wider, much like the F103. Not realistic looking but more for top level handling on carpet etc.

Mike,
Do you have the part number of the adapters for F103 rear rims?
I only saw the Ball Diff Set for Foam Wheels Item Number HPI-102917.

Thanks,

Thanks,
The plan was to post part numbers from the header cards I was saving but my 2yo got hold of them and now I can't find em. The separate parts were left rear hub, right rear hub and new alloy shaft. If you have a ball diff already then it will fit these. I had to get these direct from HPI.

Hi,

has anyone of you tried to use a 48 DP spur gear, when using the ball diff?

Is there a special spur gear required?

Kind regards,

kabus
