Unless youve got access to the the reversing gearbox between the rotors, or you have the engineering capability, facilitys and buget to make one, dont go any further thinking about making one of these.......Peter


Rick Smith, e-mail, 02.05.2016 09:02

How much would it be to buy the plans before purchasing kit?


Harry, e-mail, 22.02.2016 13:38

Looking into building one, anyone have specs. and rotor heads setup? Diagram etc. Thanks From Pa.


peter, e-mail, 01.02.2016 15:15

The whole heart of this machine is the contra rotating planetary gearbox between the rotors, is this component custom built, specialy manufactured, or off the shelf, I would love to know?I f anyone out there does know

I'm from Malaysia..I love helicopter very much...if anybody want to make an investment in developing sports helicopter in Malaysia.... Welcome...I'm very interested with..I don't have fund..but I can provide place,developing permit and other facility...I'll give high commitment in developing this flying machine...

Hello interested coaxial flyers.
My air craft division is called PHOENIX ROTOR CRAFT.
I have posted on here once several years ago.
I am the NEW builder of the Nolan Brothers Coaxial Helicopters and all of there parts. The new mane that I have given the craft is the SKYBLAZER. I have overcome the lack of horse power problems that have plagued all of the earlier models.
I do not supply these aircraft's in a kit form. For more information send me an e-mail.

Hi All,
I have two rotor heads and blades.

peter walsh, e-mail, 14.02.2014 04:33

I have tried to understand why the autorotative control reversal occurs in coaxial helicopters. Increasing the pitch of a rotor should increase the drag, whether powered or not. We know from experienced fliers that this is not correct. Why? Increasing the pitch of a coaxial rotor will cause this rotor to carry a greater proportion of the weight than the other, this will result in the greater pitched rotor trying to SPEED UP to the autorotation of this new weight, the other rotor, being partially unloaded, will try to SLOW DOWN to the autorotation speed of this new lower weight. I think this may be the simplest way to describe the control reversal of the coaxial in autorotation. All reading I have done on this has only confused me, Any one out there want to comment on this?

where can I buy the rotor head and drive system I would like to build the rest my self this winter project thanks mike


Peter Walsh, e-mail, 30.12.2012 05:56

If the last response was for me, we are using tetering rotors. This limits root stresses on the blades. During testing we will monitor flapping but I do not expect any problems inflight, worst period will be start up when centrifugal forces are at a minimum. Blades traveling in opposite directions still follow similar paths, low at the rear, high at the front, rising from rear to front. Happy to reply to emails,


Peter, e-mail, 30.08.2012 23:47

its a great machine brilliant idea .what i would like to know, are the blades on this thing rigidly attached or do they "see saw",................................Peter

i have a eagle perch for sale


Peter WALSH, e-mail, 24.11.2011 03:24

Good to read your comments on this machine. We are working on a similar project. Calculations have given us a 16ft 6" diameter, 6" chord 8h-12 rotor. Using up to 50hp {rotax 582} we should have 700lb plus flying weight. Shaft drive is to a custom built gearbox, tilting head via a simple arrangement allows the pivot point to be at a point between the 2 rotors.
Low rotor tip speed of 450'/s for efficency, unfortunately makes autorotation stored energy a little low, just need to drop collective within 2 seconds. We are quite interested to know what control forces were needed in the eagles perch so we can consider whether or not to incorporate boosted controls. Any feedback would be appreciated. Peter


DieFree@RonCadby.org, e-mail, 06.11.2011 21:17

I had over a year's involvement with the Nolan brothers. I 'sponsored' and manned booths at Oshkosh and Sun n Fun with them.

I was designing and creating a kit for the original functioning Perch and I could hover it.

The original design had many innovative and first time features:

a) Rotor head design for counter-rotating blades driven by a single shaft. The rotor head itself tilted on two axis.

b) Twin engines drove the single shaft through simple pulley reduction using sprag clutches to allow one-engine drive

c) Engine fuel systems fully independaent

d) Conventional stick-rudder flight controls.

I designed a throttle quadrant that could be manually alternated between fixed wing and helicopter pilot operation

e) A clever canted rudder design 'pointed' the pilot while moving or in hover

f) All control movements, rotor tilt and rudder, were driven by closed loop hydraulics....no cables (except throttle) or push-pull tubes...simple.

As y'all probably know, the blade span was only 12' and a single engine could carry you to a safe skid on landing.

Unfortunately, the Nolan brothers decided to sell everything and my involvement ended.

They were truly ingenious and I treasure the experience.


Peter WALSH, e-mail, 16.10.2011 01:40

This concept is rather clever. From what I can see in the video the blades have no pitch control, and will be set at a flying angle. One engine will give enough power to maintain some flying ability. The power from the controllable engine is varied to provide lift off, decent etc. I presume the transmission has a shaft from the engine/s entering from the bottom, power then passing through a differential to the top and bottom rotors. This leaves the rotors to balance the torque automatically. While many may consider this design to be crude, we should take our hats of to the Nolans for coming up with this simple concept. Just consider this machine with controllable pitch and one engine! WOW!

Mark, e-mail, 16.04.2011 00:46

THere are no plans for a Coaxial rotor system. If you order from Vortech, the plans are so fucking sketchy, you can't make out heads or tail of what to do! The Nolan brothers are not going to release there plans or try and help anyone who asks! The maggot hiroshima fuck with the "CDS I, II and III system" will not return anyones calls and there email addresses are dead links! Everyone who claims to help, has nothing to show and some bullshit ass picture from 10 yards away. You are better off building a conventional helicopter and leave these fucks to their inventions. Just my two cents.


Tony McCreath, e-mail, 06.03.2011 19:27

Dear Jack Nolan,

Information I rec´d explained no autorotate possible in your Coaxial design. This true, and why was that? Many production versions of Coaxial had great characteristics during autos? Guessing during building simplfying controls/complexity that ability was lost? Did you ever try landing on one engine, characteristics were what? Very curious!
Cheers,

Tony

Hello dear Jack Nolan,
I’m really enjoyed to have de privilege to write you some words.
Your coaxial is really fantastic. I am interesting by coaxial helicopters such the XRON 1 of Gyrodyne Company Of America initially designed by V. BENDIX. I am also very interesting by your coaxial helicopter which stupefy me by his maneuverability probably more than the XRON 1. But no tip brake, no visible swashplates … how does-it fly ??? I did not see any video or picture except some of yours showing your first fly. So I wonder if some one else ever build and fly with your model. What did eagels perch do? Any way.. I would really like to discover the secret of Nolan Brother’s coaxial helicopter.
Sincerely, Best regards.
Rob.

herb and I designed and built the coaxel Helicopter but sold the rights to eagels perch years ago we have a few parts left if anyone needs them them is a vidio on youtube nolan coaxel helicopter


vralapan, e-mail, 04.09.2010 01:34

Does anyone know at what rpm the fixed pitched rotors work? and what chord the blades have?
I assume that the skyblazer is the same as this machine...


mike, e-mail, 25.07.2010 02:32

where can i buy a kit for this? and parts are availble? finding alot of dead ends help?


Anthony, e-mail, 05.07.2010 20:47

It should be known that Phoenix Rotorcraft is the current owner of all rights to what formerly was known as the Nolan Brothers 51-HJ (Eagle's Perch). It is now known as the SkyBlazer (see online at phoenix-rotorcraft [dot] com/skyblazer). This was never sold to or owned by Air Scooter. We just wanted to clear up any misinformation.

The company "Eagles Perch, Inc." apparently no longer exists, at least as an aviation entity. A quick search on Google, when you get past all of the ancient references to this helicopter and broken links, brings up some kind of furniture company. As far as I can tell, only one of these models was ever built. It's probably sitting in someone's garage gathering dust.

Alberto, e-mail, 27.03.2009 03:33

To all interested, the Nolan Brothers sold their interest to a company named Eagle´s Perch. I believed they had already sold some Coaxial Helicopters among athers, customers in Japan.
