Also, no love for rctech? How about a link back to this thread, home of the Photon.
Ah good thinking! This is why i'm not left in charge of things. Love added, and build tips PDF'd. A toe chart has also been added (thanks DZ)

Well, by the end of the night, I bested my fastest lap ever, and was pretty easily clicking off quick laps. I'm having a heck of a time with mid-corner traction roll, though. Gonna do another full day of testing tomorrow and try some things out.

From the kit setup, I went to a medium sway up front, camber link in the middle hole F/R, middle ackerman position, 2.5 rear toe, and put a 2.5mm spacer under the rear inner links. I'm running the medium roll center links with the dot up, so I think that's medium high? I tried medium low all around and lost .3.

I've got a nice thick bumper on the car (P-Dub 415), and am happy to report that even with several good whacks on the front, nothing broke. I didn't hit anything with the side of the car, but had some pretty spectacular traction rolls. These bent both of the screws in the rear holding the hinge pin mounts to the bulkhead. I'm trying longer screws in there now to see if they're better. The existing ones were pretty short.

Any suggestions on tricks to reduce traction rolling?

Oh, one other thing. I've got some wobble in my diff pulley. Like, I can grab it and wobble it, not like it's warped. This was causing it to rub slightly on the cutout for the pulley in the chassis. The other Photon at the track also had some wobble, but didn't have the rub.

I’ve got a slight wobble too & I think it’s the diff rings - when I sanded mine I noticed that they weren’t completely flat

To stop you traction rolling you probably want to raise the RCs and a get a bit more camber change going

If you have the diff equally spaced in the cams, move the spacer from the long side to the short side should remove the rub.

There was some talk a page or so back about either pulley or dust covers not quite equal. So if you rebuild the diff with the pulley, etc, flipped over, you might get some more room, preventing the pulley catching.

Because IT IS ALMOST IDENTICAL AND MUCH STRONGER THAN THE ORIGINAL

it was a very good meet for the 5 photons that were there,

Super stock 10.5
1, Christian (xray 009)
2, Craig Mcphee (Photon) TQ
3, Damien Zarb (Photon)

Stock 17.5
1, Darren L (Cyclone) TQ
2, Rod M (Photon)
3, Ray Z (Photon)

Thats awesome that you even have that many running at your local track. I have never even seen one in person. Although I did hang around Josh's pit at the snowbirds for a few minutes. What he had there was cool.
