Looks great Frank!

Finishing details:

Permanently attached the hinges.  Took out the bent pins and replaced them with permanent ones.  I made them out of piano wire about 3 times the width of the hinge, bend one end at 90 degrees and gently bend the main part. Photo 31
Insert it into the hinges and bend the end at 90 degrees.  Photo 33

If I want to remove the pin, I pull out one end and clip the bend off.

Installed the landing gear and connected the rudder and nose wheel to the standard servo in the main compartment.
Connected the aileron servos, the aileron horns and bent wire to connect them. Photo 34
Made the canopy and glued it onto the battery hatch. Photo 35. Used the Rob Dickinson method.  Made the back end stick out behind the hatch so it can be grabbed to open it. Photo 36.
final motor installation with proper size screws.

Ready for RX and ESC installation and testing.

BTW- this design has a jet exhaust sticking out the back.  In honour of Simon H., it will be the black cap of a Tim Horton's instant coffee jar. Simon used Tim Horton coffee cups as thrusters on his model of the Space Shuttle.

The high tech jet nozzle A La Hinchcliffe*.  The Canadian edition.

The lid from the Tim's instant coffee makes a perfect jet nozzle.

Was the lid from a Caffeinated or De-Caffeinated jar?
Given that it's for a jet, I'm presuming Caffeinated

Mark,

I Googled "afterburners on jet engines".  The answer:

The size of the boost varies. For the engines that power modern fighters, the increase ranges from about 40 to 70 percent.

The lid was from decaffeinated.  I am switching to full caffeine immediately.

Finished airplane.

Am having a problem binding receivers (tried 2) to my transmitters (tried 2) and have been unsuccessful.
Will count on Temac's electronics brain trust* to help.

* anybody but me!

Well it will definitely fly amazing with that patented thruster set-up!

[msatin]

I'm looking forward to seeing it fly!

It flew this evening before training started.
Just one circuit for safety but it had more than enough power for take-off (half throttle, 5 cell, Power 46).
There were two issues I was aware of before taking off:
1) one aileron servo was half the speed of the other.  Dangerous because as elevator, it would induce roll.  Did not know whether it was a bum servo or a weak 4.8 volt flight battery (no BEC).  Either problem would have been dangerous.
2) The CG was about 1/2" ahead of the plans (1 5/8" back from the leading edge of a 12" chord wing).

The take-off was fine and the turns were solid.  Chose to land at the end of the first lap.  Problem- the nose-heavy plane started to run out of elevator.  That led to a bouncy landing and a curtsey at the end (flip). No damage.
