Hi - Max

[joecnc2006]

Picked this up this weekend for 2,000.00. in real good shape and low hours on a rotax 447 Not my ideal engine being a 2 cycle but not to bad. I can also use it to practice a tail dragger. Will have to go through it very carefully to make sure everything is in good working order. But I could not resist for that price.

Be sure to clean that air filter...  They are a dust magnet.  I bought a plane that had been sitting and the filter looked clean, but I lost power in the pattern.  The engine never quit, but it would not take the throttle and had zero power.

Clean it, then keep it covered with a baggie or wrapped up with a plastic shopping bag.  

Also, never ever pull the power back all the way after climbing out.  Do it in steps.  It will cold seize.

2 smokers can be as reliable as any engine, they just refuse to suffer foolishness.

Looks like a great snag!

Looks like a good deal at that price.

That's a good looking plane for that price.     Milton

Thinking about this some more... Is that N-numbered or ultralight part 103?  I did not see any numbers in the pics suggesting part 103.  In your checking you will want to double check the weight to make sure you are within 103 limits if that is where you want to go.

If overweight... there may be a path to register it as EAB.  You will want to do your homework there.

The price would not be so good for a static display if you cannot find a way to fly it legally.

Yes it is N numbered, legit and current, I just blocked it out for right now.
that's why the two tanks and speed is about 80mph tops

I got some new 0.06" polycarbonate to replace the rear window that was the thickness originally on the plane. The old was brittle and broke when trying to remove it.
My question is what is the best way people have found to cut the Polycarbonate, I would make it on the CNC machine but its just easier to trace the old part and cut it out than to redraw it.
I have heard some use a jigsaw, and other use a dremel.

If it is polycarbonate, you can cut this thin stuff with tin snips.  Maybe cut wide to allow some sanding/smoothing.

Those videos are for plexiglass not polycarbonate.
I was thinking of the sheers or maybe just a dremel, the polycarbonate should not weld back on to itself like plexi does. the cuts are not just simple straight cuts there are some curves to go around the back curve of the wingfoil and also around the tail section and back around.

I would discourage shearing the material. It creates stress on the edge from the pressure of shearing. Better to bandsaw and file the edge smooth.

Here is some lexan cutting...

[dz1sfb]

Using tin snips is the same as shearing. You can do it, but if was mine I would not. 

Just a note about polycarbonate: It has superior impact resistance compared to acrylic sheet, but is not as optically clear.

[Bob S.]

I sheare my acrylic sheet and then used the bending brake to crease folds on my Legal Eagle.  Only place I had problems is where I drilled holes. Lots of spyder cracks are rising out of the drilled holes!!
