Building Very easy, even for beginners. step by step instructions. needs some servos extensions wires for ailerons. Y cable is required for ailerons unless a computer radio is in use. be careful with cyano glue as it may "eat" the twin star, use epoxy ! make sure the nuts that hold the wing screws are well glued, otherwise you might risk a wing coming off during high stressed flights. CG is easily obtained with almost every battery pack. rudder is not essential, I did not connect it.
Take-off No running needed, just a straight push with full power. the built in up thrust will immediately make the plane climb.
Flight behavior Sweet flying plane. can fly slow & fast (not twin jet fast though). can be used as an excellent trainer since it have a large wing area and is very docile in every aspect of flight. when flown by a more experienced pilot the twin star holds some surprises : loops, rolls, inverted flight... 8 cells are highly recommended, 7 cells are OK for learning but for more "interesting" flights, the 8 cells really do make a difference.
Landing No sign of tip stall or anything. just bring it in slowly with some up elevator, nothing to it. On windy days I managed to catch the twin star by hand (if I can do it, I suppose anyone can).
Crash Results Nothing that can't be fixed with a little Epoxy !
Repairing  
Other comments wing easily unbolts from fuselage so carrying it in a small car is not problematic. flies great right out of the box, no need for dramatic changes. great for relaxing but also for a some aerobatic flying.
Interesting Links

From Ralph on how the painting was done

1. Smoothen the surface by filling the holes with light weight filler/spackle
2. Sand with #400 grid sandpaper 
3. Apply acrylic paint from a DIY store with a foam roller
4. Draw panel lines with a waterproof felt pen
5. Rivets are made using a "spike wheel" from a tailor shop
