Hello Guiseppe,nice to see you here.I built your 229 a few years ago,but my attempts at hot wire cutting were a failure.Still have the centre section,one these days I'll have another go at it.Did you increase the washout ?
Best regards Stuart

4 degrees, no modifications.

Try to find someone with a CNC hotwire cutter.
I did it with 2 templates and one fixed point wire.
You also may try a ribbed outer section drawing ribs with Profili2, it can easily draw intermediate sections and tabs for washout.

Here are some pictures of a few Horten wings I've built.

Brian,

I like em all!

compared to all the wonders posted here, mine is miniscule at best
but, i thought you guys might like to see it anyways.

some info: 25 inch span, 17.8 grams weight, 2 6mm motors and counter rotating props, 1s 120mah cell. all balsa with a carbon center joiner. control is differential thrust from an old toy airplane. the wing has a full airfoil that goes from flat bottom in the center section, to reflexed at the tips. transition is about half way down the wing on either side and progressively stronger.
it flies very well and needs only the minimum throttle to float along, but it can fly faster and handle a bit of wind as well.
i would like to build a larger version with a single pusher motor and folding prop, but need to get the cores cut first. something like 48 inches would be a great size to take to my local park.

derk, that is a sweet little wing. I've always liked the differential thrust setup.

Although I don't have a model of one of these yet. I do have factory drawings and foam cores for the wings already cut out for a 1/4 scale model.

Why I don't believe you can technically call this a pure Horton design (as it has 2 vertical stabilizers)It was certainly inspired by the Horton Brothers. I thought a few people might find the video of interest. I still fly the rebuild of this model and it is one of my favorites.

Hey Joel !!!

Welcome to the Nurflügel forum !

Kites or Models it all FUN !

Brian - you have Genisis too !! WOW

we are all sick !

I met Jim Marske several decades ago when we lived in the Midwest.
He spoke at our model club meetings
and EAA meetings as well as John Joncz too !

He did a bang up at a SHS meeting in Bryan Ohio b4 Dick Schreader go bad and died !
That waa a exciting meeting as he also flew his Monarch for Auto tow.

Nice Steve, what covering did you use?

Kent

Hi Kent,

is used this heat shrinking polyester tissue. It looks like paper tissue but it is much more durable.

You said in your Jan 5th post that the FMT plan of the Ho 33 was not so good a design. What do you think is wrong with it, as I would still like to build one. Maybe to redesign it and remove weaknesses etc it could be a good flyer.

Regards John

Nice thread! Here's one of mine, built with carbon tubes and kite fabric.

It's not a bad flyer, but could use some refinement.

John

Nice size, Nice effort !

Looking good !
