Albert,
Thus far the Kit is really no different then the WNW Albatros or similar Kits in their line, the challenges are the same. I'm ready to close up the fuselage (once I get back to it) and the test fit indicates a really good fit with no big gaps and no heavy pressure required. Like all "two seaters" it's a larger project, requires more or less double the effort to detail two cockpits, and the components are larger thus requiring a bit more care in handling. The only real challenge (self induced!) for me is in the scheme I've chosen, the Early Version Kit's option "A" with Schlasta 21's black and white stripes showing thru the two color vertically striped finish. Seeing your excellent results on the von Richthofen Albatros this should be an easy and pleasant experience for you, it's a very nicely engineered Kit and I'm enjoying it to this point. I'd say don't hesitate, go for it!
Cheers,
Lance
