Default Yokomo F1 Car

Hi

Why no one talk about this car when is already in the market? Can anyone share their setup? And the type of tyre use?

I just bought this recently and are new to F1 racing.

Hope to see more discussion on the this car.

Hello,
We wrote a review on it on rcf1.fr

Unboxing (in french)

And I have tested it lately on asphalt

with yokomo rubber tires (pit shimizu rebranded): light understeer and good grip on rear
with sweep racing v2 tires (front medium + rear medium): light oversteer and very good grip on rear .

Regarding the setup, the default setup from manual is already relatively good enough to play.

Hi
The yokomo YRF already comes with wing and spoiler.
If you want to try another brand you may use any wing and spoiler comaptible with F104

Regards

I can't get over the fact it doesn't use front springs. What type of dampening does it use?

Any rear wing can be used, but the front wing can only use Yokomo or Kyosho
I also managed to use a 3 Racing F113 front wing with a few modifications, like countersinking the hole in the chassis for the second screw, and it is slightly too wide at one point so it needs to be trimmed down a fraction.
Ill posy up pics shortly.


The front dampening is provided by flex in the center of the carbon lower arm.

ok here is what mods to use the 3 racing F113 front wing

Step one, the back hole mount where the red arrow is pointing that needs a few mm taken off the top,
The mount hole where the green arrow is pointing is too wide and needs the sides shaved 1 mm, sorry my camera didn't really pick up the black wing where I had done this already.



Step 2 you will need to countersink the following hole, you can just use the main mounting hole but you will find with the first hit to the wing it will move.

Here is my YRF I have been running it for a few months now and have some good results with it,

Some setup tips,

The build guide on PetitRC is good to follow and has lots of good tips,
Things I have changed from Factory,
ceramic balls in the diff and used 3 cone washers.
Replaced steering arms with Associated titanium arms and ball cups, allot less play then the Yokomo ones.
I have the updated Front suspension mount this will stop any breakages
I race on a very low grip track and found the steering kit helps with moving everything a little more to the rear and helps on high speed corners.
The Ackermann is also much improved.
For oils I have Associated 45wt in both main and side shock.
I am using the medium side springs, I found they help get the power down a little earlier.

The 3 Racing front wing has much more steering then the Yokomo one, I use these wings as a good tuning tool to dial steering in and out as needed.



Beth.

The narrow version uses a shorter carbon lower arm and top arms and steering arms, that's it, see below for the differences.

To change the ride height for using narrow wheels you just use the supplied spacers under the lower front arm mounts. And change the ride height adapter in the rear.

thank you so much for clarifying! Can you show us any Tamiya wing and body set mounted? I'm ready to buy one of these...
