Quick question i see some p12 evo with the stock steering and servo setup and some with the floating servo setup like on the p12 17. What is the advantage of doing yhe floating servo setup?

The bellcrank seems to make the car rotate harder in the center of the corner (thru rear traction loss). I took the bellcrank off when I went to the UK and sadly it took me until the snowbirds A-main to put it back on. That was a big fail on my part.

When racing at CARS the weekend before the world's I felt the std 1/12 steering produced more corner entry steering and had more gear grip (less sliding).

​​​​​for CRC black carpet I think the bellcrank is a big advantage, especially in slower classes

I'm running the bellcrank on my stock car and it feels super easy to drive with mega corner speed, I've been running the direct in mod and I've never felt as happy with it as the other car. Will try bellcrank in that at some point.

To add to Mike's observation (and my jury is still out), it may have a lot to do with grip level which servo mount works better. I have 2 local club tracks, 1 is a bumpy roll out/roll up bull ring that is probably a 2 out 5 on the CRC black carpet grip-o-meter. The other is a semi seasonal very flat flowy regularly vacuumed that could be as high as a 3 outta 5. I dropped the traditional float mount on the bumpy track and nearly went 0.2ths quicker in 17.5 stock vs my bell crank car that night. Repeated the same test at the flat flowy track and it did not yield anything different other than "feeling" around certain corners.

I am going to test the bell crank shimmed up 2mm + shimmed ball studs to see if the effect is coming more from bumpsteer then how the servo is mounted. I'll find out this Wed.

Ackerman (for want of a better word) has a significant range with the bellcrank. With the ballstuds all the way back there is only 3 degree less outside wheel deflection for a 20 degree inside wheel. Makes for quite a feel difference.

With the bellcrank, I run the optional longer ball studs with 3-4mm of shim to control the aggression of corner exist steering.

With 3mm it pushes more

​​​​​with 4mm it wraps the corner more

Optional ballstud--
4.3x15.8mm Ballstud, Steel, 4 pcs

Just purchased my first Roche and was wondering which servo saver everybody is using? or will the standard XRAY servo saver work (got 3 of them)

I'm using an Xray stiff saver without any problems. In fact, it's the only one I had that met the 19mm distance spec in the instructions. Also, the one pictured in the instructions is an Xray saver.

Hi guys, I need some information. My rear tyre diameter 50mm. I am using pinion size 22T and spur 96. It seems that the car is not enough power for that kind of tyre size. Running a 6.5T motor blinky mode. What is the correct pinion should I try for that tyre size 50mm. I do not wish to true the tire as I don't have any tire true for 1/12 . First time running an EP pancar. More to GP car.

We run a 35mm rollout with 3.5 blinky on carpet

As for lack of a tire truer -- id highly recommend investing in one or at least asking someone to truer your tires for you.

For a 6.5t blinky I normally aim for a rollout of about 55mm. So with your tyres you'll want gearing of about 32/90 (or 34/96, but unsure if you'll have room for it). Your 22/96 is way too low. If you don't have a truer, look at brands such as Ulti - they come trued to 46mm out of the packet, which will be better than 50mm.

Is there another batch for wc pods coming out for this car?

roc-156019 it perfect the motor mounting on it.

Unlikely
There could be 1-2 left in various people's pit boxes right now around the globe...

Anyone know where I can find some more front axles (spring steel) part number 330016? Seems that everyone is sold out right now.
