What you say is interesting.
Would you give us some details?

For the mainshaft bearings, just remove the upper flange that holds the upper mainshaft bearing in place, and remove the lower flange that holds the lower mainshaft bearing in place. As long as you are using the mast collar in the stock position (between upper mainshaft bearing and swashplate) everything will hold in place just fine.

I finally had to change out the mainshaft bearings on my heli last year, they wore out and got notchy.
I got a fever! The only prescription is MORE 6HV

That's sort of correct. Larry and Peter (century) were together on the Intrepid at first. I got a prototype, and didn't like the dubro v-tail mixers on the aileron servo (was mounted in the frames) or on the elevator (there was no "X"-arm). At the time I was pretty anal about geometries on control systems, and it took a while to figure out what to do, but my original "fix" had two blocks of spruce between the collective arms, thus mounting the aileron servo inverted, removing the dubro mixers, and removing interactions. It took a while longer to figure out the elevator, but it ended up with one of the very large futaba servo wheels, reemed out, with bearings jb-welded in the center, mounted on the collective arm pivot via a longer bolt. This was a simple way to make a do-it-yourself bellcrank <G>. Adding push/pull to that was obvious. I flew it that way for a while before venturing up to cassopolis one weekend, where Larry's son put the drawings into CAD, and the first "real parts" were made. I remember Taya looking at the machine for quite a long time at one of the trade shows,.. probably Toledo. About a year later the Raptor came out. Larry deserves credit for the control system,.. I just "refined" it <G>

One of the very first Bergen Intrepids ever made was sold to Shigetada Taya, and the Raptor line of helis hit the market about 2 years later (or thereabouts). If I'm not mistaken, true credit for the finalized Bergen control system goes to Gary Wright. The Intrepid prototypes had the aileron servo in a slightly different position and were using something like a Dubro V-tail mixer. As I understand it, it was Gary who came up with a prototype which placed the aileron servo on the collective lever, and thus a design was born.

I've been told the story before by the people who were involved. I think I got the details right...

I guess 10X has never seen my Titan fly. All Raptor parts available from TT, or your LHS and have 31 degrees of pitch collective, and go well beyond 8 degrees of cyclic if need be.
I didnt see your Titan fly,but i saw your ZERO G conversion fly.
YOU ONLY LIVE ONCE..IF YOU LIVE IT RIGHT THATS ALL YOU NEED
