This might defy common convention when gearing spec type motors... but I have found that using the largest possible gear combination to reach a desired FDR seems to yeild better results than simply throwing the smallest spur gear you can find in the car and gearing accordingly.

For instance this past weekend I was doing some testing running a given FDR with a 116 spur... when someone else was testing with the exact same equipment and FDR but with a 112 spur, he felt like he didn't have the same grunt out of the corners that I had.

When he finally put the 116 in with the same FDR, he immediately felt increased bottom end performance.

Theoretically I think this would be due to the fact that with a larger spur you are:

1.) Gaining a better mechanical advantage on the lay shaft/drive train. (torque = force x lever arm distance)

2.) larger gears use smaller tooth deflection angles and this results in less efficiency lost than gears with larger tooth deflection.

Obviously you will not be able to reach certain gear ratios with certain spur/pinion combinations, but when figuring out your gearing choices I would always try to find the largest combination possible.

Hi,

Sorry, here's some information on my setup that may help you to help me.

Basics & electronics
I (will on monday) run for first time my Xray T2 EU 009, on asphalt (see the youtube video with the track) with rubber tyres (Jaco Green) or RB 4xfront foam tyres (shore 35) with a Mazda 6 bodyshell.

Car is "perfectly" setup with a hudy according to the T2 manual (EU asphalt)

My electronic is : Tekin RS PRO (v189) + Tekin 6.5T (on a 21T pinion for the moment) with a 48 - 84 Spur.

Tekin RS PRO setup:



I have in stock also a 87 spur and ordered a 17 & 19T pinions

According to the manual, here're the FDRs :

Spur 84
17T:8.40
19T:7.52
21T:6.80

Spur 87
17T:8.70
19T:7.78
21T:7.04

Hope that helps,

1/ what is the FDR to go for the 6.5T motor ?
2/ any remarks ?

Cédric

Hi Cédric,

The track seems to have pretty long straight lines, I would run with a 6.5T brushless motor, a ratio between 6.2 to 6.5
Jaco green seem to be a good choice with the cold weather in France, however you live in the south of France, I would recommend a 32 shore rubber tire with warmers. Why not using the GM36 french spec tire ?

Another point to consider is the flex of the 009, I strongly recommend you to get the asphalt top deck and/or taking out some screws under your chassis.

have fun next monday !

cheers,
Raphael

Are there going to be any other colors available for the 009 this year?

Salut Raphael,

Thanks for the help ! I'll go first with the 21T pinion (fdr of 6.80) that should be smooth and less agressive than if I get a lower fdr. Especially with the Tekin RS 189 update; they told me to gear down.

Many folks at my local rc club run foam tires instead of rubber (cause they grip way less) but I'll give it a try with my Jacos.

32 shore should have a good grip for sure.

I removed screws under the chassis according to the manual. Chassis is really flexible

Merci pour ton coup de main,

Cédric

im wondering if anyone out there knows where to get a 64p spur gear between 70-78t to fit on the x-ray
im going to see how fast i can get one of my old 007 chassis flying and need a tiny spur to fit my massive pinion, 80t is a tight fit, i think 78 would work

Make some tests but I am pretty sure that with the long straight line you would choose a ratio around 6.4

Jaco Green is 28 shore if I am correct,

Just put some tire sauce like LRP asphalt or even better Paragon ground effect if your local track allows it and warm your tire, you will get the grip required.
for your information, we use the GM36 spec tire on carpet without any grip issue
