Marske Pioneer II or III

Does anyone have the fuse drawn up in Rhino and be willing to share the file? I would like to possibly get a plug cnc'd. Or even a built up fuse would help considerably. Any help would be appreciated.

Marske Pioneer IID

I own this one, built back in the early '90s by Bill Kuhlman. I should advise you that it is a difficult sailplane to thermal at altitude, as it is a real challenge to nail down the pitch attitude. The short fuselage (my wife calls this one the "flying egg") makes it hard to tell if the attitude is level. I usually manage to keep the roller coaster pitch excursions to a minimum, but it never does settle down in turbulent lift. Aerotowing can also be bit of a go, if you should scrape a wingtip on launch. The short-coupled fuselage will go sideways quickly, and all the rudder in the world won't stop it.

That said, I do most of my flying with the Marske Pioneer on the slope, where none of these drawbacks are evident. It sure looks weird in the air, and there is no mistaking it for any other glider in the gaggle.

The fuse on mine is made of fiberglass, using the lost foam process, so no plug, unfortunately. Have fun with yours, and do post a build thread when you get it underway.

Don.

Thanks for the replies guys. I have the 3 view and cross sections in AutoCAD so I may end up going with the lost foam route. I was looking for the Rhino file because I have access to cnc and was going to have a plug done.
I read an article somewhere some time ago about the "flying egg". I will keep you posted as I make progress.

Don......have you ever thought of putting a "gyro" on elevator? You could put it on a switch so you could control when it "helps"! As far as towing....build a "dolly" for it.....I know they don't look the best....."training wheels" as we refer to them.....but it would eliminate the tow problems.

What an excellent idea! Thanks, Tom, I may just have to try that sometime.
