Default 3D fun-fly - what incedence?

Hello, I am building a fun-fly 3D airplane out of foam. I have all the pieces cut out for it and ready to assemble. I have not cut out the hole for the wing yet, as I am a little unsure of the incedence. I am modelling mine after the Tower Hobbies Fun-51, with a few tweaks to the design. I noticed that the wing on the fun-51 has a little bit of positive incedence. Is this right? If so, how much? My goal with my design is to have the flight characteristics nearly identical right side up as upside down. My horizontal stabilizer and the wing are right on the thrust line. If I angle the wing up a bit then I am going to have to hold down elevator when upside down to fly level. Is there any way around that? This is the first 3D type airplane I have built.

My design is made out of pink foam, 1" fuselage, 1/2" tail surfaces, and 2" for the wing (hotwired fully symmetrical airfoil). The dimensions are: length=38", wingspan=48", wing area=720 sq". I am not real sure what the all up weight will be, but I am guessing around 4lbs so just to be safe lets say 3.5-4.5lbs, which puts the wing loading at 10-13oz/sq ft.. not too shabby! (just an estimate though) I am going to use an OS .46AX for power and a Futaba 9CS tx.

2-3 degrees right thrust.

Tell us more. Are you saying - Fully sheeted Pink foam?
Is there a fuse reinforcement? How about the fuse caps?
