Dave, that wing looks interesting.. I take it's foam core, sheeted and then cut out between the ribs?

Nice!

Greg

It's great to share ideas. I've included another photo , showing the wing at the mid point of construction. This build system uses a Geodesic fixture that slides over the core and then the foam is removed by hot wire. Then the remainder of the balsa caps and end pieces are glued on. Wings, this way, are very straight and lite and easy to build.

I'm interested in this type of construction, but it is beyond my ability.

Garf,

I always liked quoting lines from movies. Been doing it since I was a kid.

Did you see the movie "The Edge?"

Here's the best line in the movie. I've also been saying it long before I ever saw the movie.

"What one man can do, another can do."

Dave, sounds similar to the technique we were using for f3a wings, but that was honeycombed and then fully sheeted.

How does it go in regards to torsional stiffness?

Seems i can't find the pic of the wingtips anymore!

Guys

Seems somehow this thread has been moved from the org. posting....hummmmmm

Ray
I'll re post the photo of the tip.

Curare
This wing technique is very much the same as we did on the Pattern wings. I've used this style for 20 years plus. The foam is cut with a template and then the remainder of the capstrips and end sheeting are installed, give it a final sanding ,,,,,done.

Excellent, mind if I steal the idea?!

Greg, we don't steal in this hobby, we just borrow.

I did one like this about 15 years ago, but I used structural foam. I think the plane ended up with Dave Gardner. It worked fine and was pretty light. I cut the vertical stuff prior to cutting the airfoil and horizontal cores. Easier that way.

Ahh I think I know what you're talking about, something like "Laser building" as shown on the CLAPA site?

like this? http://www.google.com.au/url?sa=t&rct=j&q=&esrc=s&source=web&cd=6&ved=0CGIQFjAF&url=http%3A%2F%2Fwww.clapa.org%2FBLUE%2520FOAM%2520CONSTRUCTION%2520FOR%2520CONTROL%2520LINE.pdf&ei=Qv4nUaOHLLCUiQeauoCQBw&usg=AFQjCNHuiBL7OyKmeQHOhzefdb3Yqj6gVQ&bvm=bv.42768644,d.aGc&cad=rja
