Hi nitrobasher
I built this model 5 years ago. It came out heavy plane the rudder was modified ( bigger ) in order to do nice 3D you will need not less than .91 engine 2C . 4C are to heavy for this model.
Make sure that you align the wings to the fuselage.

You will like this model but be careful it is unstable on normal flight!
It likes to do maneuvers no long straight flights
