The steering cranks are the same part numbers as before.

When they introduced the RB6 they mentioned the changes between it and the RB5. My guess is that they left some of those changes in the RB6.6 information even though they didn't change it in the RB6.6.

Hopefully someone has some time to put a parts list together for those that are just upgrading. ;-)

$399.99.

One thing that they don't talk about but looking at the manual it appears you can run a 4 gear laydown transmission like Tanner is currently using.

Plus, with the 3 gear transmission the wing now mounts behind what I am calling the rear bulkhead. That should make it easier to get access to the inner ballstuds. I am curious if you could run a three gear laydown with the wing in that position, something tells me you can but I won't know for sure until someone confirms.

I think my buddy Kraig just needs to create an "official" (such a dumb term) RB6.6 thread.

IMO

Based on that list, it might be economical to convert from a 6 to a 6.6 - just need suspension mount, bulkhead, choice of transmission, chassis, side plates, and battery strap. What's a good estimate for those, maybe $200?

It's because no one has the p/n's yet. I would also guess that Kyo America doesn't even have them on their site yet. It'll be a couple days/weeks probably.
