X5 Help!

[Extreme]

Just about to order my X5 and was wondering what spur gear to use as i run a checkpoint 10x2, having read various posts it seems people are using the larger spurs for getting better gearing?

any advice greatly appreciated

thanks

The larger spur gears were really introduced for brushless motors, which just run better with really low ratios (11:1, 12:1 kind of ratios). The stock spur in the kit is the 104, and that should be a great starting point with a 10 turn motor. Here in the US I'd recommend a 17 tooth pinion with a 10 turn, but due to the different tires and surfaces (assuming you're in the UK) I'd really recommend whatever the other guys say.

hi there
on a std spur and a 10 wind brushed i would say around 16-18 depending on track and conditions

Think I only ever ran brushed once in the car but I reckon the 18 tooth for the 10.

Thanks for the advice guys

have ordered 106/108 spur gears as well for the car what pinion/ spur gear is going to be the best combination on the 10x2?


will be running the car at Eden Park this sunday

cheers

around the same as mentioned may be up one 19 not much more

[Big E]

Start with 18/104.

I should be there SUnday if you have any problems just ask!!

obviously i have the kit spur, and have ordered a 106 and 108 spur as well,
which one would be best to use with the 10x2 at eden park Ellis?

Also what oil/ pistons?

thanks

[Big E]

Try the kit 104 to start with, really not to sure with brushed to be honest.

Shock wise, front: 40wt orange piston green spring

Rear: 30wt blue piston white spring or pink if you can't make a rear roll bar.

I used to use 18/104 on a Checkpoint 10x2.

What I suggest you do is try 18/106 as a starting point, and if you want more punch go to the 108, if you want more top-end, go to a 104. Be aware that changing 2 teeth on the spur is going to effect the ratio by less than 2% so you might not notice much effect, whereas changing by 1 tooth on the pinion will effect the ratio by over 5%.

I was running 18 or 19 -104 with a brussed 10 turn Reedy motor at Eden Park.

Just check the heat on the motor after your run. to be honest I didn't notice much of a difference from one tooth.

I'm making the jump to a 10.5 brushless this weekend though just to slow myself down.

My plan for the regional is to keep it on 4 weels and learn to drive again.

Cheers for all the advice
cant wait to get the kit and start building it now!!!

[Extreme]

Ok any ideas where i get the white rear springs from as Ellis suggested????

[dancoog]

Got mine fron DC racing on Thursday, very quick turn around..

Keep in mind that his suggestion was to use white springs if you can make up a swaybar.

If not you may want to go to a slightly harder spring like pink.

Cheers,
in the process of making up a sway bar, do you know what strength? have various ones in different thicknessess,if not will make a new one up
ive already made one for the x6 but havent really had cause to try it yet!

thanks

[dancoog]

Ellis is your best info on this.. but while you're at it will you make one up for me as well??

[bigred5765]

i have 3 which we change to suit track conditions
a 0.8mm
1mm
1.2mm

[Big E]

I run either a 1.2mm or 1.6mm bar.

Either will do though to start with. And even without it the car is not terrible with a white rear spring but it is better with it.

Just bought a Sway Bar Kit for my X5 (TLA-4257 for a XXX4)

The sway bars themselves do not fit the X5.

Does anyone know where I can get the wire to make my own ?

Cheers

I guess the Trinity Sway Bar set for the XX4 is the one everybody uses ?

I guess it would be a direct fit.
