Knuckle is connected to the upper arm, upper arm is connected to the damper tubes. Lower arm is fixed and acts like a shock tower. The upper inner arm is the fulcrum point so actuates the damper tubes.

Try mocking one up and you'll picture it better. Pretty simple to rig up actually.

I have the HPI super softs mounted on Ride wheels for my F104, this is what I mounted up on the F10. Very cool that I can use these now on both cars. So it stands to reason that you can also use F104 foam wheels and foams ? If so, what's the benefit of F103 foams over F104 foams ? Thanks !

I don't know- you'll have to let me know if you find out
Seriously though F103 rears are much wider (more grip!) and there are more compound choices for F103. Given time there should be more choices for the F104.

Wait... So f104 wheels fit the formula 10?!?!? i am having a horrible time finding tamiya foam tires.now, F104wheels/tires.... theyre eerywhere!

So... any F1 class in CFL? Adam... you know of any and what are the requirements. I found about 6 silvercan motors in my closet and i know that 99% of F1 classes uses them as the motor of the class.

Hey Mike, any chance of some up close detailed shots of the dampner tubes. I think i have the concept down, but the angles of your car don't make it very clear.

It's something I think i'd like to try in the future

For those running 21.5 and foam. What rollout are you using ? After digging around various threads it seems like 85mm - 90mm is the range for 21.5 F1, but wanted to verify. For testing in front of the house, I'm running the 95T spur that came with the foam ball diff and a 25T pinion which is giving me about 50mm rollout. It seems fast, but is a far cry from 85mm ? Also, if 85mm (ish) is correct, what spur have you found to be best to allow for rollout adjustment as the tires wear ? Thanks !

I have been thinking about going brushless 21.5 though.... anyone know the general rules about f1rc and motor/esc requirements?

Hi, I have some questions...
Hope someone can help me out.

This is for my F109.4
- Is the F10's rear tyres the same height as the F104's?
- Can I mount the F10's rear tyres on F104 rims? Or I have to mod the rims?
Need to use more stickier rear tyres.


Im getting addicted to Formula 1 kits thats why Im buying an F10 kit soon.
Need to confirm some things...
- Whats the maximum ride height I can do with the F10? (building a street spec)
- What hop ups do I need to make it handle a 10.5 BL setup
- What are the weak points of this kit that needs to be addressed with hop ups

Thanks in advance

10.5 bl is too much. and the max ride height is pretty high, and parts to upgrade are knuckles/diff (if you want to go foam)
ball diff if you want to keep rubber and shock.

the tamiya f103 friction pads fit/work with the f10.

Im running 10.5BL on my 3Racing F109 (F104 spec) with rubber tyres
drag racing with M04s and M05s. So Im accustomed to the speed that
it brings, more fun than my 4WD TCs.

Thanks for your input.

How bout the tyres? Will they straight fit on a F104 rear wheels?

no clue.

F1 is a different beast. Im used to 2.5 and 3.5R's but F1 is tough to control at that speed on rubber. foams will make it twitchy, best of luck on your adventure.

I recently found out that using f104 foams up front and soft rubber tyres at the back makes for a "point and shoot" F1 kit.

Very stable at the straights and brakes straighter too.

Can anyone here who also has the F104 rubber tyres compare it with the F10's
tyres if they have the same inside tyre diameter?

Yes, the long circled ball end swings inward when the arm swings up and so the dampener tube plunges inwards.

Hope that helps!
