Frank put together this 1957 era Manx Cat from scratch, building it from plans he drew based on an old magazine article. Put a 36 up front and she flew great right off the table! Nicely done, Frank!

I want that.

Dahm, I remember that thing from a million years ago, oops I just told my age!!
Seems that G.I. had that model published in, I believe M A N when they were a real model mag, but any way it flew real well, and I thought that they would fly it right from the table...

Looks like a fun model

EddyR · « **Reply #4 on:** January 05, 2013, 03:19:02 PM »

The guy launching the model made a big mistake. When launching a wing you always step outside the circle as you let go of the model. Many times on the first flight the model will come around and get you if you do not step out. Most people flying wings for the first time will give a little up and do a loop. This cat looked very stable. Mine were super sensitive and very fast. I had a green head with a 8/8 prop on it. It was fun watching the video.

Neat stuff, thanks for the vid.

Here's mine, flew it once this past summer. McCoy .35 Redhead power, flew right off the bench too and much better than I expected...

Phil Hawkins · « **Reply #9 on:** January 06, 2013, 01:03:45 AM »

Very cool Vid! Thanks for the laugh!

I have been looking for a bi-wing project, was going to eventually look to build something like a .38 Special, but I think I just found something way more cool!

Perfect. Excellent job Wayne! love the McCoy on it too. Is that about a 3 oz tank?

Phil Hawkins · « **Reply #10 on:** January 06, 2013, 01:05:57 AM »

Anyone know a source for plans? or what magazine it can be found in?

Flying Models Feb 1957 - Anyone want to give Bob Buragas the designer credit?

John Craig · « **Reply #13 on:** January 06, 2013, 07:44:41 AM »

This is my choice. I would rather build than cut ribs.

Mine is built from a Walter Umland kit. Very easy build. Has not been flown yet. True about the launcher hold the wings by the outboard side. Witnessed a few immediately going in the wrong direction on launch. By the way I gave the pilot a ten for landing and the plane a twenty. Great video. Thanks.

Ah yes, the old Manx Cat IV from February1957 Flying Models Magazine.

Long ago and far away (1959 in Green Ridge, MO), a friend of mine built one of these and covered it with parachute nylon. This plane is very simple to cut out and build. His plane was AeroGloss dark red and powered by a K&B.35 greenhead. It was always in a hurry! It was steady as a rock in flight and quick in maneuvers. "A tail-less terror for combat fans that'll turn on a dime and give 9 cents change" as the Flying Models Magazine article said. It was then and is now, unique in flight characteristics and presents an unusual appearance in flight. A real fun airplane........I have the plans.............might have to build one of these critters!.........yes..........those were the days.

The model shown on Walts forum is mine and I made one change to it. The leading edges are 3/16 balsa and I replaced them with spruce. I remember the trouble I had in 1960 when I built the last one and the lower wing had a nasty habit of breaking the leading edge on landing.

I have always considered building a Manx Cat and just never got a round toit. One change I would make is to redo the bellcrank mount to move the bellcrank and leadout guide up in line with the vertical CG. As I recall, the article mentioned it flying with the outside wing down.

I'd have to check Phil, but I think it's 2-1/2oz. That's plenty of flight time for this one!

As mentioned above, if anyone builds one of these I would also highly recommend using something other than just balsa for the wing LE's. My particular model is actually a restoration I did of an old beat up 'Cat that was given to me by Bob Smith from Sig Mfg. It has 1/4" wooden dowel L/E's, someone was definitely using the old noggin' when they originally built it.

The Manx Cat IV was published in Flying Models, Feb 57. Plans are available from the AMA plans service. The 1957 Aeromodeller Annual featured the FM plans and the article by Bob Buragas.

Hey Doc,

how'd you like the adjustable lead-out guide and wing alignment jig features of the kit?

john e. holliday · « **Reply #22 on:** January 07, 2013, 07:23:13 PM »

Well, I followed your instructions as close as I could. Haven't flown the plane yet. Still needs a fuels tank.

Had to do some corrections to message. It's either my fingers or the keyboard that the grey matter is not getting thru to.
