OK guys- here's the deal: I'm working on a BIG slow plane. I've been fiddling with it off and on now since about November or so, and I'm ironing out the last details now. I'm going to use it primarily as sort of a giant scale slow flyer, but I also want to use it as a cargo lift and a glider tow, but mainly just BIG and SLOW. Specs below. My question: what angle of incidence should I use on the wing? Gut instinct says 0 degrees, but I want to get some oppinions from the pros.

Name: eh, I haven't given it that much thought. Desn't really matter too much
Construction: Balsa, Ply, CF, Foam.

WING
Span: 144"
Chord: 24"
Aspect ratio: 6
No taper, diehedral, or sweep
Airfoil: Clark Y
Ribs, foam with balsa cap
18" center section permanantly mounted to fuselage, 8" above thrust center line.
Two outer halves joined on aluminum tube

FUSELAGE
Profile, foam core sheeted with balsa and ply, CF rods to reinforce.

TAIL SURFACES
Foam and balsa , removable for transport.

Thrust line and elevator at 0 degrees unless otherwise sugested.

Thanks guys in advance.
