I'm working with Kevin on the narrower rear blocks. Should have designs done shortly. We'll do a small run initially to test then get into production depending on demand. To give you an idea, the blocks will be designed to use the existing RB6 rear pills and when using A/A with the new blocks it will be about 2mm narrower than Din/Din.

Very cool, will look for those blocks for the winter series at Delta. For now with sugar tracks, we need to remove rear traction from the rb6 lolz

For now just MM as that's all we run in SoCal. But if there's enough demand for RM hangers it's certainly possible. We're strictly in the design phase now, still need to prototype, test, then produce.

Yup. When I used the drill press on Saturday I noticed a nice difference. I was also on 1.6x2 and 30 with golds. My buddy also ran the arms in his main so we could get more feed back and really liked the new hole.
Have you tried the new hole plus inside on the tower?
I'm also D-in on both.

AZRC4Me,
You can count me in for a set. If you need testers hit me up. Thanks for taking on this design task too.

Guys? How much further in do you drill the new holes?

I have done it in two different spots, flip the arm to the single hole side and measure 4mm towards the outdrive on center. I've also measured 17.5mm out from the sway bar hole. Its all trial and error right now. Hopefully if this proves to be an advantage maybe Kyosho can make us some arms.

Has anyone checked the weight balance front to rear with the shorty back and esc forward versus the esc between the motor and shorty? I was told that at least with the Orion esc, the shorty/esc/motor configuration is more weight back than the esc/shorty/motor configuration.

I've tried mine various ways and the battery back is always more weight, even with the Orion.

Here's the latest setup I've been running with the rear arm mod.
Still some tuning to do but it feels pretty food with this so far.

I managed to get my RB6 MM weight bias to 35.6% front / 64.4% rear whilst still hitting minimum weight.
