BHOFM

It's made of wood, paper, and rubber,, with just a
bit of plastic thrown in for good measure.

I taught a tech class in a Jr. high school on aviation
science. We bought these in bulk for about twenty
cents a piece. They come with a heavy white paper
to cover them. I reduced the weight by 60% using
tissue and sanding the wing ribs to almost half their
original thickness. I also drilled out the wheels to
lighten them.

It is raining hard at the moment so flight tests will
be delayed a few days.


18" wing span.



First test of the engine at full throttle. Has a little
vibration but we can live with it. Tied it to two
pounds of lead to hold that roaring monster back.

This is a "scale model", I assume and the full size is down the road a little bit after the clocks and the boats...Right? bill NICE!

If you're not making dust, you're gathering it. After I reread my own posts, I agree with myself even more.

I'll bet the full size model has one heckuva rubber band.

very stealthy .. pilot to co-pilot

How about using band saw tires!

And I think I started the whole thing down the fast track or into the wrong airspace. Sorry, Mike. It does show that lighter by which ever means, takes less horse power to move the object. Something about Newton's law..... bill

If you wind the propellor backwards, the plane won't fly backward.

DAMHIKT!!!

After careful balancing of the aircraft I did a couple
glide tests. Moved the wing forward about 1/2".

First powered flight, 1/3 power, 100 turns, wind just
a bit heavy, Altitude approximately 25-30', distance
traveled, approximately 150', time of flight, approximately
45 seconds.

It held into the wind perfect and then as power
faded it turned right in a nice 5` glide to a perfect
landing. At one time in the climb it just stopped all
forward motion and kept climbing. This accounted for
a large part of the flight time.

Thanks for the comments everyone.
