Neat wiring job. Does it matter if the receiver is placed on top of the servo? I think it adds some space to place a motor fan, between motor and esc.

You generally want to keep the weight as low as possible. In very low traction conditions it may not matter as much and in some cases may actually be more desirable to have a higher COG, but with high traction every gram you can keep down low helps.

Slick wiring job entitymugenmtx. Really nice job. Just needs a ReVtech motor to match the orange ano

I some space between receiver and servo. I took out the fan because it burned, a fan will fit just fine.

Xray T3 2012 ready for outdoor season! Just need a little fine tune from basic asphalt setup for now (HB silver springs, 2mm bumpsteer and removed some screws from the topdeck) and the car is great!(for my local track,e.g. worlds 2012 track) , maybe some more wrenching is required when the tempature here gets up in de next few months and grip level gets a little higher.

The best (cheapest) way I've found to do this is build a pedistal to the same height as a set of scales (I used standard digital kitchen scales), then, using the bars from my tweak station I would place one bar accross the pedistal, the other accross the scales, zero the scales then place the car on the bars, front axle on the bar on the scales and the rear on the bar on the pedistal. The reading on the scales indicates the amount of the cars weight that is on the front end. Turn the car around to weigh the rear axle. Check the reading on the scales and this will tell you how much weight is on the real axle.

Compare the two readings and you get your front/rear weight distribution.

If you add the two readings togeather you get the total weight of the car.

NOTE: you must weigh using the axel's, not, say, with the left right balances, and don't forget to have your body shell, battery etc in the car.

Also, changing the wheel base will alter your front rear weight distribution

Is it just me or is that motor plugged in wrong?

No you are correct, B and C are not in the correct positions,, just plugged it in quickly for the photo, motor went out after it. Sharp eye though

The stock carpet/rubber setup calls for 350cst and one closed hole front and rear.

If I wanted to stiffen the dampening can someone explain the difference between closing one (or more) hole(s) and going to a heavier oil?

If you closed holes on the piston, you would create more shock "pack", where as if you just went to a heavier oil you would reduce the rate of travel.

"Pack", the way it's been described to me, is just what happens on initial movement of the piston. When the piston hits the volume of oil, for a split second the oil acts as a sort of solid, creating pack. If you increase the number of holes in the piston, there is not as much area that allows that pressure between the piston and the volume of oil to build up, therefore reducing pack.

Thanks. So both will slow the dampening but closing off holes will add some initial resistance to dampening as well with pack.

Default Shock positioning

Hey,

Could someone please explain the different handling characteristics between adding a 1mm spacer between the front shock and tower and also adding a 1mm spacer between the front shock and tower but also running a 1mm spacer at the bottom on the wishbone?

I know both of these changes calm the front end down but im assuming in different ways?

I would like to fit tamiya shock on my t3.
What is the best way to put it on.

Tamiya caps with tamiya gold balls ? Or xray caps with xray balls ?

Thanks
