Hi thanks for the information Nimo, i think that change all rear diff/axle hubs, etc.. is very expensive, that improvements offer to mod this pieces?

F104 axle is shorter than F109, so you won't fit the F104 diff unit unless you cut down the F109 axle.
Was going to look in to the CRC axle tonight, but just remembered it is the night to go to the local indoor beginners club to help new racers to get control of their cars before they venture out to the proper racing scene.

I made the "robk CRC rear spring mod" - works extremely well and makes tweaking possible as well .
Springs come rated from soft to XX Firm. Soft and medium worked best for me.

I too have gone to CRC side springs
Made a huge difference to stability, even if the track has always been wet

Hey,
I am running my car for the first time this wednesday night. I have put in a hobbywing 13t system. Can anybody help me with gearing. I dont have any 64p pinions so need to buy some and looking for a good starting point for it. I'm using the kit spur.
I'm running on an outdoor asphalt track. (Meakin Park in Brisabane for anybody that knows it)
Thanks in advance.

Not familiar with your track but I would reckon to get 23T thru 25T as good starting point.

I too have gone to CRC side springs
Running my car on a medium traction asphalt track and I used a very very hard main spring. Came from 1/10 gas car. Not sure of its rating but it really plants the rear.

Mine has still to see a dry track, but on Sunday the club chairman and I took our F109's out on the puddle covered track with our waterproof speedo's and sealed can motors and Cross rubbers and it was a laugh.
We had so much grip on the very wet track, and going through the standing water to splash those looking on
I even spun my car in to a 3" deep puddle and drove it out again with no ill effects, so the cling film around the Spektrum RX does work
I have now put longer rear arms on my F109 as doing that improved rear end traction on my GenX10, and have also added a rear diffuser.
Bring on the rain, I'm ready

I remember running my F201 at Southampton years ago, some of the puddles were over the front wing. Had so much grip. The great thing about F1 is that the shells are almost like an underbody, as the wheels are on the outside.
