I have never even attempted to balance my car on the wheels. I just pick it up by the whole in the shock towers and call it done. A year ago, I didn't even balance my cars. I just put anything where ever. Balancing left to right did help me a lot.

I can order up some scales and give it a shot.

Default axle pin: set screw or aluminum pin holder

I just realized that there are two different methods to holding the axle pin in. There is the set screw and the aluminum pin holding collar.

Is there an advantage to either?

The set screw is cheaper. . The axle pin covers relieve the stress on the pin and cvd and the assembly feels more free. Maintenance is easier also and no worries about a set screw backing out.

Default roll center?

Hey Guys,

Attached is my setup for the 2.25 lipo (stiff) chassis. This is the setup I used to win the South Africa Nationals and also the same setup I've been using at Norcal Hobbies (home of the 2010 Reedy Race and 2010 Roar Nationals). It's slightly different from my 2009 Reedy Race setup.

If you get a chance give it a try.

If you are using the standard 6 cell rubber chassis then use the Medium High roll centers.

EJ
what is a med high roll center= a bit that go's on the car? are they the plastic parts that capture the hinge pins? if so how do i acheve the med- high setup? i notice that the pieces are marked "l" "m" and"h" but it shows 2 of each on the setup sheet! whats the different between the 1st "H" and the second "H" on the setup sheet when the box is checked. or does it have to do with the inserts placement inside that bit. i noticed when i first built my photon that the inserts can be fliped for different hights.can someone explain this to me. i'm sure its kinda important if i want to try this setup!

You answered your own question. The holes in the aluminum inserts are off center. So when using a medium mount, it can be medium high or medium low based on how you put the insert in.

Med-high means put the center of the whole lower. This will raise the mount a little.

thanks! i was thinking that direction but it still doesen't explain why on the setup sheet it shows 2 highs followed by 2 mediums followed by 2 lows,on the drawing it dosent look any different between the two highs, like the insert has been fliped. just trying to figure this out!i'm also assuming that high means holes more towards top,low would be hole closer to the groundthat part of the setup sheet has always confused me!

There are 6 roll center options on the car. Like pakk mentioned, we have 3 suspension mounts H/M/L (High/Medium/Low) and the insert that goes inside these are vertically off center. Depending how you insert them they can be in the high or low position. If the line is up, it is in the higher position. If the line is down it is in the lower position.

When talking roll centers I always like to start off with the mount then insert. So if I say my roll center is in the medium/high position, that means I have the "M" suspension mount with the line up.

Hope this helps to clarify.
