RE: Fliteskin Ta-152 H1
Never built anything that big but I'd go 3-pc built up. I like foam for simple wings but hate making templates et al to know where to dig foam out and insert mechanisms. I'd rather build internal workings as wing progresses on bench. My Judy, for example, has retracts, flaps, dive brakes, bomb drop, nav lights and ailerons. I contemplated foam but am glad I didn't for making this stuff fit into a 69" wing was 'testy' to say the least! My $0.02 That will be a neat airplane!
