  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.

  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.

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.

The landing gear is anything but straight forward. The ME109 gear are a hydraulic damping electric actuated with a compensator. The over center locks on the 109 lower and raise the gear;  they also see very little in the way of landing loads, up, rear, and torque loads from spin up and breaking are transfered into an upper trunion stay. Most of the loads the down lock see on the 109 are side loads which translate into  tension and compression.

The fan trainer on the other hand uses a completely different  setup. Spring steel gear leg perpendicular to the fuselage,  it utilizing scrubbing form the tires for dampening landing loads.  spin up, breaking, and landing loads are trasfered to a lower longeron saddle ala cessna 210 style. It would appear from pictures that the gear utilize an over center A and H arm type down lock . However I can't confirm this without a better picture of the gear itself. The interest here is in the kinematics of the down lock which are nothing like the ME109. Other than the gear retracting into the wings, that is where the similarities stop.
