37T or 38T are both good. You can always change your pinion gears if necessary. However, my experience has been that I've never found myself lacking punch out of corner with this car whatever the size of track, but sometime I do wish for more top end. So I'd gear on the tall side just to be safe.

Thanks Jeffrey. That is what I was thinking. I will run the 37's and just swap pinions and spurs as I need to. Maybe I will set up my RRR for the biggest tracks and use the 05RR on meduim tracks that have super high bite.

I agree with Jeffreylin although I have yet to find a place where I could use either 23T or 28T gears, but at some I do use the 20T gear (mostly I use 21/26), this is using the 37T rings so maybe the 38T rings would be the better option.

Hi

Im using 40 in the front and 39 ring in the rear. Is it better if i change them to 38 or 37 ?

Here is a the layout of my local track. By the way this is kyosho 5th world cup track in Dubai.

How does your car get out of the corners? if you fell like you have too much punch then use the 37/38 option, but if you are bogging out of the corners then stay where you are, clutch set up also makes a difference.
I am running 37 but the 2 tightest hairpins (4inch kerbs) at my track means having the clutch bite a little later but at my 2nd track the tightest in radius is 2feet so I have plenty of punch there.
I like using the 37 as it gives me a much longer 1st gear for the infield sections.

I already have the 39t hardened bevel gears, and with my motor, I could probably use the 23t gear, and I already use the 28t Mugen gear (Mugen gears last a heck of a lot longer than Kyosho gears) and with my habit of running tiny tires, the 23/28 combo would probably work well.
Using the standard gearing (and 39t bevel gears) the low-end was so powerful that it just spun the tires if I pegged the trigger, and the straight was almost painful. I found going to the 22t pinion gear gave me what seemed to be much quicker acceleration from just about every corner... and sometimes with the 22t gear, I still feel the motor could pull a taller gear.

I'm just voicing my experience with this car (for no reason in particular). I still love the way this car has so much punch! Its a ballsey-blast motoring around the track, lighting the tires at will .

Thanks everyone for the imput. I have 39t steel gears now but I think I am going to get the 37's and go from there.

Just got a FW05R andd and planning on running a Sirio EVO2 motor with it, but need some advice on a pipe to choose and where to get it from. Thanks fo the help in advance.

jeffreylin

Hey Carl long time no see. Are you back in LA? The best pipe for the FW is the Skyline VR12S. I tried just about all of them and this one works best.

What is the different between the A,B,C steer

Quietroit

Is the FW 05R is for small or big track because I'm getting run down on the big track straight way (225feet). I have all the O Ring,opion,spur gear. Need help!

Are you running the Blue Kyosho 23/28 pinions?

NiMo

With the 37T diff rings fitted your top speed should be faster than an RRR.
I dont even rev out with a 27T gear on a 24ft straight.

jeffreylin

The RRR will have a faster top end. I've ran 37T with 23/28 on a 200ft straight and the RRR come up on top everytime. The pipe you use for the FW makes a big difference. The best I've tried is the skyline pipe.

I know in theory if the FDR is the same they should have the same top speed at the same RPM. However, I think the way the FW's exhaust is oriented (i.e., 180 degree as opposed to 90 degree like most belt cars) limits the engine's output at the top. The FW also has a heavier drivetrain. While it has less rolling resistance thus accelerates faster, the heavier drivetrain eventually saps up more HP at the top end too.
