I flew this heli today and fly's better than the original set-up.. Its holding out better also and much more responsive...Couldnt ask no better. Ahhhh am loving it...Only have one problem..Theres this empty space bare shaft where the old elevator bellcrank use to be. Will the shaft has a tendency to bent in that area?...

I suggest there is nothing to worry about. If you crash hard enough to bend the main shaft, who cares where it bends.
Nice looking, and simple, conversion. Almost makes me want to resurrect my old one.

Don't worry about the shaft it will be fine. I've been flying a very similar setup for over a year and have never had an issue. It looks like 2pac is using 120 ccpm while mine is setup using 180 ccpm.
IMO (and friends who have flown it) the heli is a lot easier to setup and flies a whole lot smoother. I attribute this to fewer linkages and less slop. I'm very happy with the conversion and would never go back .

Exactly what you said Mike..Its 120 CCPM, its just a simple conversion like cfranks mentioned..No Slop and no worries about the servo being swinged, anyone can do it too quite easy. All you have to worry about when moving the bellcrank mount back a little is the clearance between the main gear and the bellcrank. The Elevator mount is the same original parts to where i just inverted the mount to clear the servo arm against the frame. Just a matter of imagination...No machining...Ohh..i take that back, i did a little CNC on an old swashplate to make it looks like the new one. After that its all off my ROTO ZIP who did the cutting on the Carbon Fiber sheet..I did a couple of tanks again today and the response i get from my input are awesome..I'm still worried about the main shaft though. I'm thinking of mounting another bearing block right in the middle.

2Pac, the part of the shaft that is worrying you is supported either side of 'the gap' by bearings, right? Look above the top bearing! You have a longer piece of the shaft that is only supported by the top bearing and that doesn't bend during non-crashing activities! I really wouldn't worry about it.

MichaelC, How does this work if the elevator servo is only connected at the back of the swashplate. With the setup at 180 if you give an elevator command, don't you end up with interaction since the two front connections will be pulling/pushing at the center of the swash?

No there is no interaction. With 180 ccpm, if you give elevator only the elevator servo moves and the swash pivots on the two 180 links. If you give aileron the two front servos move (the elevator does not) and the swash pivots on the elevator link. The only time all three servos move is when you give a collective command. You just need a radio capable of doing 180 ccpm.

Hope this helps.

hmm

Looks good. Very similar to my setup in my gallery. Has a nice locked feeling in flight. I ordered the newer style lock ring in mine and have not had the main shaft move at all since.

Looks good.

Doc,

Thanks, yours looks good too...But one thing, how did you get the throttle servo closer?..I dont like the long throttle servo link. It seems like its much more aggressive if the throttle link is a little shorter...Back to the drawing board..I'm gonna make the throttle servo closer for a shorter rod..

2PAC, where'd you find the carbon fiber to make the servos tray from?

throttle servo

That was done on the cnc. Lookup 'Helidog' from ND and he may be able to get you that plate that you see. I didnt see your throttle in the pictures, but if you can try to get a slide setup similar to what I have. Lock in place and go. Rodney didnt tell me where bought it from, but it has worked super.

If you cant get it closer maybe goto a 440 rod setup(ball and link) or from a Vario setup. They are much more rigid than the tiny rods we use on our min airs.

The throttle servo is still under the tray. I have an access to a CNC, manual mill and even a water jet with a full access to a titanium sheets if i can just get a good look at it i might be able to figure out a way to make them. Or i just use the rest of the CF sheet to attached it somewhere close to the throttle itself..I'll figure out...thanks
