I really don't know, just a guess it will be a updated kit to for the sideways battery and laydown option. Like someone else said likely a lot of carryover parts. the current car is pretty good.

Some RB5 parts work on the RB6 don't they? I have a complete RB5 and enough spares for it to start a small RB5 parts shop lol

I am guessing the front end will remain pretty much the same in the new car. Kyosho should introduce a new chassis for the verical battery position as well as the laid down transmission.

I would love to have some extra features like accepting the "old" transmission for dirt use for example...I quess we will have to wait and see...

I'm assuming the reason we don't see a genuine Kyo mm 3 gear trans is they are planning to include it with a new kit. Probably mid motor only with the lay down trans as an add on. Guessing similar geometry to the RB6 but with sideways shorty supported, 3 gear/4 gear mm.

Hoping they may go for another conversion, or at least a choice, just bought an RB6 along with an RZ6 conversion, so it would be nice to try the laydown car without the need for a full car buy again.

First time out last night, after switching back to RB6. Brought a used one locally and the previous owner had butchered the chassis/side pods for transverse battery. Wow what a difference, car felt awesome. Very consistent and predicable.

Depends on if you have a RPM stator (short stack) or Torque (standard stator)
General rule of thumb as it was explained to me, was to start 3 teeth less on the pinion from where you'd run a 17.5.

So for example:
17.5- 33/69
13.5- 30/69
Just as a starting point
I normally use a short stack/rpm stator for both 17.5 and 13.5
17.5- 30-31/69
13.5- 27-29/69
Should be close as a starting point

If you want to use a different size spur, say a 72 avid/schelle, do the math to get the ratio as close as you can and go from there.

Thank you sir! I found a brand new 70t spur and slipper pads in my parts box, no clue where it came from or what it's out of but it works! Can't wait to get my new RB6 on the track...just switched over from AE. My RT6 is on it's way as well

I ran my first main even, I finished 5th. The RB6 is just super smooth. This is my first race with 2WD mod.

It is unbelievable how good the software is on the Orion R10 Pro, messing around with Turbo, and boost is really great such a smooth power transition when your at that thin line between grabbing, spinning, and the nose lifting just a tiny bit.

I'm use to SCT 4WD racing. So, it's amazing how clean my RB6 always stays.

I ran Schumacher cut stagger tires in the front. With mini pins rear on my dusty groove track the front dug in like crazy when turning I had to adjust end points way down on steering .

Very predictable car though. Love it.

What is the word on a new kit? Will it happen this year or next?

I think it's just an assumption,because of some new stuff the team guys are running.. But that's not to say it's not going to happen.. Maybe a updated kit. That's all the rb6 needs is just an update.. Only new Kyosho part I've seen new is the wider chassis, the 3 gear trannies are not Kyosho,as far as I know
