I am working with a different material and construction technique that looks good so far. It has good stiffness (excellent torsionally), while still being resilent enough for crashes.

I have a sample 12" wing half that I can throw hard onto concrete without any damage. I would not recommend it for combat, but should be able to take a lot more abuse than a typical composite.

I should be able to vary the construction to go from a medium weight up to much higher weights.

A few details still need to be worked out, so it will be a while before I can offer something for sale.

I will be working on a prototype. Tooling is expensive, so I was going to start small with a 48" span plane to test production techniques and such. I'm thinking of keeping it simple with 2 servos in the wing and an elevator servo. I haven't decided on a one or two piece wing yet.

Would there be any interest in plane of this type and size? I personally like planes 60"+ in span, so it is difficult for me to judge others interest in this.

Sounds cool to me! I personally prefer at least a 60" / 1.5m plane as they tend to work best for our local flying sites, but a lot of people like the extra "handiness" of the 48" size.

What type of design are you thinking about? A slope racer like the Thorn, or ?

If you really want to stick to the 48" span, and this material favors medium to heavy weights, then maybe you'd consider a PSS plane? Everybody loves a Mustang...

Steve,

I was preferring to stay with a slope racer OR maybe a stylized racer like a Jart or Slope Stream. I love the PSS stuff, but it is not as marketable. Most of the PSS guys make their own, which is the beauty of PSS....the differences in the planes.

I think I should be able to make a medium/light plane (30-35 oz and 60" span, 20-25 oz and 48" span), but I won't know how light until I try making a few.

Hammer time!

AndreasMergner · Oct 29, 2007, 04:16 PM

??

I can't be the only one confused.

mr_editor · Oct 29, 2007, 04:21 PM

You have a new material. You also have a new plane called The Hammer. I put two and two together and called my good friend MC Hammer.

Would this have helped?

or this?

AndreasMergner · Oct 29, 2007, 04:48 PM

Ah yes, but Hammer is a preliminary name. Not sure if it will stick yet.

We love naming other people's planes though. How about:
"The Thing" from Fantastic Four.. Mostly indestructible
"Juggernaut" from X-men.. Also indestructible but also once moving cannot be stopped

Oh and back on topic- I like the 60" plus planes. Bigger if you can do 2 pc wings.
Will there be more Thorns?

Chief High Horse · Oct 29, 2007, 05:09 PM

I would consider smaller. I think a 36" - 42" wingspan three servo plane might sell.

ShredAir · Oct 29, 2007, 05:26 PM

Andreas, you have my input: 60" or bigger assuming the tooling will cost about the same as for a smaller plane.

SchiessCo · Oct 29, 2007, 06:00 PM

I think something like Le Fish would be awesome - something that really benefits from composite construction and bouncability. 60" seems like a magic number regardless.

Will this new material get covered like foam/EPP, painted like composite, or left unfinished? And are you thinking about a thorn style fuselage or something more traditional?

AndreasMergner · Oct 29, 2007, 06:06 PM

It will not need to be covered. It may be painted or left "unfinished".

Is the Thorn fuse not a traditional sport fuse? I was going to try and go for a similarly sized fuse, but faired/filleted more and with a cross tail...but it depends on the size and design style.

infopimp · Oct 29, 2007, 07:28 PM

My vote - 60"... or more.
