Ray,
I was looking again at the Rotodyne... it is an autogyro as well, as I re-read the post.  It's really an amazing model. 

I like the X-2 as well as the S-97 so whatever you decided to do, I'm interested.  Found a 3-view of the S-97 and did some copying in my CAD program but found the sizes of the three views didn't match in size.  I thought that was interesting!

I look forward to seeing your work.

The Kayaba plans are available on the HPA forum. FYI.

I think a cook up on this autogyro would be cool, it is pistachio size but it can be blown up to any size.

I think that a cookup of that Kayaba might be fun.

Can't wait Ray...put me down for a kit/plan when you've finished the work!  I hope we might do a cookup chopper build maybe!

Hello Bob,

I actually offer kits as they become ready, the Commuter was a laser cut kit but was not very popular so I discontinued it, I am designing so more kits so as they become available I will let you know.

Cheers, Ray K.  Wink

Oops, ment to say plans for the X-2 but the S-97 is just as easy to do.

Cheers, Ray K.

How the Commuters rotor tube drive works is pretty straight forward, a rubber motor runs thru the rotor tube, one end of the motor attaches to the bottom plug hook the other end attaches to the top rotor plug which attaches to the main rotor hub, this rotor tube assembly free spins within the fuselage, when unwinding the main set of rotors turn CC/W while the tube mounted rotors pick up the torque reaction and turn C/W which results in automatic counter rotation. you can see a video of this at work on the HPA forum on the Commuter build.

Cheers, Ray K.  Smiley

Hello Tom,

Glad to be aboard, funny you should mention the S-97, I have partial plans already drawn up, the mechanics for this to work is quite simple, I plan on it to be an autogyro with counter rotating rotors that free spin, no power applied and the pusher prop doing all the driving.  Wink

Sorry Ray, I should have linked you with your posts on HPA, since I already commented on the autogyros on HPA.

Ray... so glad to have you aboard S&T, been following your post on HPA and they are very inspirational!  I like the looks of the Commuter and saw the Sikorsky S-97 and was thinking a power setup like the Commuter might work on a model of the S-97.  But the S-97 has a pusher prop on the rear as well. 

I'd like to try a heli in the near future.  Your RotoDyne (sp) is something else!  I look forward to following any of your posts you'll be sharing with us. 

I'd be interested in more details of the counter rotating power shaft in the Commuter. 

Once again...love the Heli's

Yes I do autogyro's too, here are some pictures, one is a Kayaba which went OOS the other is a Rotodyne, I have not worked up the nerve to fly this one yet.

Cheers, Ray K.
