they would require different c-hubs to fit the 'fat' ecs joint through them. more info -

i haven't. if your looking for traction why don't you remove the 'inner' four top deck screws? or put o-rings under the 'wings'

Hi guys,

Wondering if someone can do me a favour and measure the distance between the front bulkheads on a photon, and also let me know if the spool bearings are flush with the bulkheads or if the eccentric bearing holder spaces them in at all, and if so by how much (probably 1mm if at all). Basically I'm hoping to fit a roche photon spool in another (red) car

Thanks heaps

Yes I know this mod, but remove 4 iner screws on topdeck, but in case of a crash is a weak point...
O-ring under the wing screw? or under the wing?
I run also single layshaft

thanks

I've only done these tricks on a dirty/tree pollen covered asphalt track.

The orings is between the screw head and graphite. Only one per wing.

The orings trick could work in the topdeck but u would need smaller orings

Default C-HUBS

I'm sure this has already been answered in this thread but I can't find it.
Can someone tell me which C-HUB beside the top ones will fit the Photon, it seem everybody is out of stock.

xray will fit (may need a little filling for a snug fit)& you will also need the xray metal colars top & bottom for as the top ones are different

Xray hubs will fit with some sanding to fit in the arm and shimming to take up the play between the knuckle and hub. You need to use the xray bushings also. Comes out to be a $30 option. You could look at hotbodies hubs for the TCX and Tamiya 417 hubs. Both arms were very similar.

I run 1mm shims for trackwidth not 2mm
I always run the middle hole on the tower.
I usually run 1.5mm shim on the inner camberlink. Sometimes 2mm
I always run 45 or 42.5 losi shock oil in the front
and the alum front knuckles are not good for rubber tires. The ackerman difference between the outer hole on these to the composite ones is massive. This could be a major part of the problem here.

Rear:
I run my car with wheelbase 2.5 front of arm 1mm rear
Question? about camber link plate? Are you running the optional plate in the rear super long? Like where the screw is on top of the bearing? If so that is wrong you want the middle hole here. This is also another major issue if that is how you have it. It will make the rear super lazy.
Rear tower I usually run the 3rd hole in sometimes the 4th hole on carpet
usually run 42.5 rear losi oil.
5.5 rideheight rear 5.2 front

I also usually run the weight I had to add on the front of the battery and servo but that is up to you. The car should be easier to drive the farther forward you put the weight.

Battery pushed all the way forward also.

Try all those changes. Please try them all together at one time.
Did all changes and mounted a new servo E/W . After so fine tuning servo set up car drove great on a green layout ( at prolevel rc in st louis MO this weekend ).
As traction picked up car got really tippie and after a full day of 70+ cars practicing started to traction role. Ended up asking around for advice from non top drivers that were willing to help and ran across Bill Sider , sure i didnt spell his last name correct . He seemed to know about the car and had me makesome changes . This was a 35-90 track very tight drive line..
ended up going to 55wt in front shocks
moving shocks in 1hole at top f/r,
-3 deg camber in rear
long level rear camber links ( no shim on hub carrier) in rear
farward ackerman with #9 insert
5mm in front 5.4mm in rear
with 0 toe in up front seemed to work great for the main . O any was running new jaco tires with no compound by mains. ...

Had a great day with the Photon today... Car is working very well on our low grip, large, flowing asphalt track.

Still curious about the release date of the new car.... Any word?

I ran my EX tonight against a pretty stout crowd of 17.5 boosted cars.

Tqed and Won. Car was great all night. The way I'm running it now the car has great balance and is really easy to drive.

The car just got better as traction came up.

We are practicing again tomorrow and it should get even better.

I'm anxious as to see how my current setup will work on "Snowbirds" bite in a couple weeks.

But right now its pretty dang good.

You guys are gonna like it.

Gotta say Larrys new ride is a freaking beast. Full tilt everywhere on track and looked like it wanted more.
Design is very interesting ....
Perhaps a new ride in my stable should be considered.
Top has one hell of a wheel man.
