Thanks for the bump steer shims Cpt. This week I will try 30mm plate instead of the spindles with 2mm shims.
There's a rhythm section where my car gets upset after which a huge triple so it HAS to be perfect through there . I hit it 3/4 of the times but the 1/4 times happens on a first lap then boom .

Default New from GMK Supply

Shocks as great as the Kyosho Big Bore Velvets deserve their own complete set of great tools, and now GMK Supply has them. GMK0145 is the complete set of 3 wrenches: shock body, aluminum cap and bottom cartridge, and GMK0146 is just the bottom cartridge wrench. CNC cut right here in New Joisey out of 6061 alloy aluminum, we tweaked the designs several times until we were satisfied we had the best possible wrenches. Treat those Velvets right!

Talk about a bunch of copy cat bs. At least i know mine was original. Kinda annoyed though. I would also like to thank all the people who did buy my wrenches and appreciate you guys helping to support a fellow little club racer. Hopefully i will have the opportunity to bring you all some new genuine tools and parts. As i have stated before please feel free to pm me any parts or tools you would be interested inseeing

I use a Eurus with 409s receiver. I just bought a RSX One-10 Servo. I use an Orion R10 ESC and 13.5 motor.

The servo worked immediately but it wiggles all the time slightly. As it sits on the bench you can hear the servo working and it shakes. Is this a voltage issue?

I was told to install a glitch buster in the extra Rx port and it didn't help at all.

Sounds like either u dont have it centered properly, you have binding in your steering rack or maybe you have a servo that isnt 100%. Some digital servos do make noises even when are just sitting there too

Our track is clay with lots of traction but is described as not high bite like OCRC so our setup is really different. Everyone is running slicks now and its very fast. When the traction goes down a bit the rear end gets loose and spins out easily. What is the first adjustment I should make to fix this? I currently run a shorty battery fully back in car with a low pro servo. Is there too much weight in the rear? If I move the battery forward what will happen? Less traction I assume...

The RSXone10 did make some noise, at least mine did, was worried as I found
it was less on a regular RSX but perf have been awesome so I kept my cool yet
I wonder if a direct lipo power might be a nice thing on this one for more steady torque.

On the track it seems fine and one of the best I've tried so far.

I got the latest KO module with 411 receiver, a real upgrade on my book.


Have you tried to progressively remove flex screws as the grip went down ?

Sounds like you need to change tires if your spinning out that easy. Try some scrubs up front or something with more tread in rear.

If you guys run slicks then try the hot bodies pink compound when traction reduces. I have had the best luck with those. I tried losi pink and my car would bobble more.

I had put a MYLAPS transponder on the back of the servo because its low pro and I had the space. I unplugged the transponder and the servo immediately quieted down. I didn't realize this was an issue (assume now the top of the servo is better shielded). It still makes a bit of noise but not much wiggle now.

What is the performance difference btw the 409s and 411? I was recently told that the 409s is better in nitro as it is less affected by the vibration. I have not had any interference issues with the 409s. Only this servo issue.
