I think tower hobbies had a .40 sized model of one of these designed to run two .25 nitros. i really wanted to build a non scale.version of this plane for a while. either that or a variaeeze or other burt rutan model. i like the idea of a fully functional canard, but I'm afraid to actually impliment.it.

good luck chellie.

Canard? :confused:

fhhuber 04-18-2014 10:39 PM

VariEZe was/is a canard design

http://en.wikipedia.org/wiki/Rutan_VariEze

It has a fixed main canard surface with elevator on it.
Some Canard designs (including the Wright Flyer) have/had "flying stab" forward surfaces where the whole surface was moved to act as elevator. Some have fixed forward surfaces and depend on elevator/elevon on the main wing for pitch control.

Lots of ways to do it... you can mix and match flying stab + elevators on the forward surface and elevons if you want.

The flying stab is easier than you might expect.

Lol! Fh, I thought he was referring to the Cessna!

Ok, I got to thinking about this build, and Know What ???? I have a Dynam I can Fly Foam Plane Laying around here :ws: its been well used, so its ready to live another life :D
I am just going to use the front fuselage, and cut it a little behind where the wing mounts to the fuselage, That will work, then i am going to build a new wing out of 3mm depron, and make the rudders and stabilizer out of 1/8" balsa sheet, the wing will need to be moved back a little on the fuselage to give it the 337 look, and I will have to build up a little foam on the rear of the fuselage, Frankenstein Build :D

Real trick is keeping the booms light but stiff. Its very easy to make a 336/337 tail-heavy.

I had the Nitroplanes big 337
(336 is fixed gear with a different air scoop at the wing TE.... going 336 makes going scale easier and allows easier wing mounting/removal)

Note your photo showing cooling flaps open for the rear engine... pretty much required on 336 and 337 to keep them open all the time.

Yea, I was thinking how to make them lite and yet be able to run a control wire through them, I think a ladder stick type build, with a 6mm CF tube on top will work, that should keep it lite, I Hope :D

CHELLIE 05-24-2014 12:13 PM

I Got The Motors Ordered, just waiting for them to get in, I am going to be Using my favorite 1800kv Micro Motor :ws: They are a little motor that think they are a big motor :D They are a little power house and only about $6.00 each, if you never used these motors, give them a try, i use them with a 7x6 apc prop and a 30 amp esc with a 3 cell lipo of about 1300 to 1500mah, they can be pushed, they have thick windings, i use them at about 20 amps and about 220 Watts and they love it :) just use a little epoxy to to help hold the wires at the motor and use a little epoxy on the motor mount so the motor does not turn in the mount and break the wires coming out of the motor, here are a few videos of this micro motor in action with a 7x6 apc prop on 3 cells, enjoy, Chellie

Hi Chellie
I shall be watching this with interest.
What will be its span?

Just for interest the booms on my 53" O-2 (337) are hollow built up in 3mm Depron and nothing else - no reinforcing at all!

Looks like a really good starting point for the subject Chellie. With a bit of vision, there's a lot of models that are good starting points for bashing into subjects that will probably never be offered off the shelf.

Below is my GWS ME109
Two GWS ME262s
and my GWS Zero :Q

xmech2k 08-21-2014 08:42 PM

Those are incredible, BillG! Love those rarely modeled planes!

The Wing Span is 44", 39" just did not look Right, The 9mm Depron sheet is 39" Long , I am using the TLAR Method :) LOL, That Looks About Right

Looks nice. Brilliant use of that 'I Can Fly' model. You've really captured the look of the 337. Good work!

Got some more done on the Build :ws: the steering linkage gave me a bad time, it kept binding, no matter how i ran the tube and wire linkage, it kept binding, its a tight fit in the fuse, wasted 2 days trying to get it to work right, then a light bulb came on, forget the tube and wire, mount the servo on the bottom of the fuselage to a external steering arm, with a rod, Success :D no more binding, Head kind of hurts a little from beating head on Wall to get it to work :eek: :Q just have to install servos now and go fly it, Dang, just one motor on the front will allow this plane to hang on the prop, 180 Watts at about 18 Amps, with 2 motors running, it should be a Rocket, I know the rear motor will unload a little with the front motor running, both motors are micro motors, 1800KV with 7x6 APC props, yes i remembered to remove the red bec wire from one of the ESC :) Almost done with her, should have it done tonight. Take care and have fun, Chellie
