Some people have had to sand the diff housing narrower because when inserted into the bulkheads they can put pressure on the diff making it feel bad. Since I was running super lightweight oil to try and get it to turn in better I just took the seal off and ran it without any oil inside except for some light lubrication. That narrowed the diff down so it didn't feel like it was binding.

When I find some time to give it some love I'll rebuild it and see if I can find anything as I do like the idea of a low/no maintenance gear diff =]

During my searches I found one diff from spec r which may (or may not) fit. It's for the Tamiya M06, has anyone tried this diff? http://www.spec-r.com/default/index....roducts_id=360

I did a few laps with the car at my local club on their carpet track. Not really set the car up or did anything with the tyres and the car lacks steering and pushes a lot but it's a lot of fun to drive. I don't know enough about F1 to say it will be quick when I have tuned the understeer out of it but I'm sure it will be even more fun =D

I'm thinking of changing tyres to sort out the understeer. Right now I have Pit Shimizu soft grooved tyres front and rear so I was thinking about changing the rears to medium.
Hi Vince. I am also loving my 3racing FGX but with a little modification at the front end. I find it a bit stable using the F104 fronts than the FGX steering system. I am just waiting for G-Rem's belt conversion before altering the rear.

Cheers!

Hi G-rem.

How are you? Yeah, That's the chassis I am planning for the belt conversion and so glad found someone who can interpret what I have in mind.

Can't wait to start the build.

Regarding your conversion, how's it? If you need someone for you custom chassis, you can contact Paul of Bezerk RC. I attached his facebook page so you can contact him. He's so nice to gather all what I need for the chassis.

You don't need to give up, just try Paul.

Best regards,
JC

Hi JC,

you will finally get your conversion before mine, can't wait to see how you will do it, the chassis looks so nice how much does it costs to get one like yours?

Which parts will you use for the conversion (gear diff, motor mount,...)?

Thanks a lot for your anwers,
Best regards,
G-rem

Gentlemen,

I am really enjoying watching your builds. Glad you found Bezerk. I might have to contact them with an idea or two.
I hope you can get your belt drive cars working. I'll certainly be watching.

Hi Nutdriver, he is so nice. I contacted Mike of Exotek but he told me he can't do a single custom chassis order- should be bulk so I ended up with Paul of Bezerk RC.

Good day, G-rem and to all.

Sorry for the late reply. So tired last night because of the half- marathon I did.

Anyways, this chassis will fit both belt and conventional 3Racing FGX rear drive system. This chassis will have the front end of the Tamiya F104 so I am calling it as hybrid.

I am about to use the TQ racing belt-drive modification here. BUT, I am eager to see your version which is tidier. I just want to know from you if you alter some holes from the chassis or the parts you told me will fit from the current FGX chassis. Please do let me know so I can buy the parts you have and report back to you.

The custom chassis I designed costs me 130 usd including shipping from Bezerk RC.

Hope I answered your Qs, sir.

Best regards,
JC

Hello JC,

thanks a lot for your answers, I really like how this chassis looks I didn't think about the side pods plates and it's really cleaver (and your explanation on the other thread really convinced me).

For the parts I will use, you have to drill extra holes for the motor mount and the opposite shaft holder (5 holes in total). Depending its location on the chassis, you will maybe have to cut the rear fixation of the upper plate and use the location of the current bodyposts to fix the upper plate on the chassis through M3 aluminium tube (not sure it is very clear...).

I don't think there is other alteration of the chassis other than that.

Very curious to see how your conversion will look!

Cheers,
G-rem

For the FGX. I'm thinking about sectioning out the shaft bearing retainer from the rear bulkhead by cutting from the motor side parallel above and below the retainer to make a slot back toward the diff cup. Then rotate the cut piece 180* to move the bearing forward, about 4 mm, without limiting the motor movement. Then make a 50 mm shaft for the pulley (Stock is 45), drill the two 2mm holes and tap the end for the retaining screw. Robinson does make 49, 52, 55 and 60 48P spurs. The belt would need to be custom measured. the motor mount would need to be notched to fit the new placement of the center shaft.

34 tooth diff pulley, 19 tooth drive pulley, 49 tooth spur and 30 pinion:

(34/19) * (49/30) = 2.92 FDR

Something to play with.

Sounds interesting! Can you post pics of your modification?
