Thanks for the quick answers Tony and the set up Larry!

Just a follow up regarding the shocks. At our track, I generally run 17.5. Are you guys using stiffer springs because you guys are running faster lower turn motors therefore the stiffer springs reduce body roll? And if I were to use softer springs, can I get away with using thicker oil instead? If you’ve got a simple explanation that would be great.

Regarding the aluminum steering blocks and the rear hole being in a different position. Can that be fixed by using a different steer length position on the bell crank? I would like to get the aluminum one for durability and also when you buy the plastic spares, they come as a package with the rear hub but I’m assuming that doesn’t break as often and I don’t need that many extra.

Thanks,

Ivan

Good to know. I've been using the front hole on the plastic blocks as per the base setup ....I thought the car felt goofy mid corner to exit. Would that be the result??

have a question for yours, how do you tighten the pinion? I can't find space to insert the key...it's new lipo Chassis 2,25
under chassis, there is a hole in spur gear area, but I can't tighten pinion very well...

Build the shocks to the "normal" length, it's fine - just don't try and tighten the bottoms all the way up the thread, they won't go that far without damage! A few threads will be visible but they will be concealed by the spring cup.

Droop is normally measured to the bottom of the loop on the rear hub, and to the outer lower edge of the front wishbone. For outdoors/rubber, I would personally start at 0 rear/5 front. For carpet/rubber I would go to 1 rear/6 front.

I just picked up one of these cars, I need to order some parts. I am confused on the difference between v2 and v3 drive shafts, the difference between the 3mm collar washers and the wide 3mm collars. Also what does changing the o-ring in the shocks accomplish?
Thanks in advance

The V2 axles have 2 universal pin holes, V3 have 4, and are interchangable. The dogbones are the same.

The Ultra Wide Collars are used under the suspension mounts to adjust toe. The small od collars are used to adjust camber link height.

Some racers prefer the 40 durometer 'o'rings to the stock 30's. On the V1 shocks they seem to leak less. On the V2 shocks we use the 30's

Gathering info while waiting for my Photon to arrive.

The statement above make me wonder if Xray 10th sedan shocks can be used with the Photon.

No need for that. The V2 shocks feel better then a Tamiya shock imo and leak no oil.

OK...but I already have two sets of Xray shocks and all the springs I need.

The new kits come with the v2 shocks. And if you run xray shocks you'll never be able to use any setups posted on here because getting the shocks to feel the same as the kit shocks will be basically impossible.

And I cant explain how important it is to get your shocks feeling right on this car. It makes a world of difference.
