Flight characteristics:

Nice sports plane, not a 3D killer.
No right engine trust results in a lot of rudder input on vertical flight!
It needs way more throw on the surfaces than the recommended settings to get it really going.
Standard 60 oz servos are sufficient for this plane.

Construction weaknesses:

No right trust!
Top of rudder doesn't have a rod. Is just a piece of balsa and very weak.
All hardware is metric, so hard to get spare parts in the US.
Sloppy wing tube assembly.

  JR R770 and Hitec's HS-6965HB digital. Overkill for this plane and they'll be replaced for an R700 and 635's on the ailerons and elevator. My favorite HS-81MG for throttle. Small and very fast.
Robart steel pin hinges.   Gorilla glue.
I had to enlarge the slot by 2x 1/8. Heat shrink tubing keeps them together. Gear used is the Graphtech #114.
Header tank for better fuel delivery. Saito 100 and Perry VP-20 pump.  
  Carbon rods.  
   
Carbon control rods self-made.
