Any idea how I can find out some information on this airplane. I need a drawing
on the
landing gear. I looked all over the web and the info is scarce at best.

Tony


I have very little info. Just a few pictures.
Performance was bad given the amount of HP it had.
Not surprising for any ducted fan.
The drag of the duct starts to outweigh the advantages starting around
130 MPH and up.

Though I do appreciate your response with performance graphs and drag COE for ducted fans.
My quest is for the LANDING GEAR......... Not the ducted fan or any other aspects of this airplane.
I thought maybe somebody in the group may know someone in the Thailand area that could snap a few pics for me of the LANDING GEAR......  if not may have to fly there myself and have a look.

Tony

There are other people on here that might be interested once they see a picture
of such an unusual airplane.

The landing gear is straight forward and used by several other airplanes.
It simply rotates 90 degrees up into the wing along a longitudinal axis.
The same as the ME109 except the ME109 legs are straight.

Tony,

Are you interested in copying the ducted fan airplanes landing gear exactly? Perhaps you are interested in the principle of the mechanics so you can design the components yourself?

My Seawind has a similar bent gear design that folds into the fuselage and wings.  I have hard copy illustrations of all the parts.  I've won't be using the parts and have redesigned my gear to fold into the wings. Those components will be much too heavy for your plane.
