Is this ARF any good? Construction? Covering? Flight Characteristics?

I've been looking at this plane myself. There are a couple reviews on Cermark's page that might interest you.

I reviewed it for RC Report magazine. Excellent flying airplane. Takes off straight as a string-full power & go. Very precise. Fast, very fast. I used a Magnum .52XLS and it was moving out. I finally put a fun fly, low pitch prop on it. Lands nice, but a little fast if you have only flown trainers. Hard to slow down it's so clean. Never made a bad landing with it. Hard to see. For me, anyway, it needs some red or yellow. The teal & white is pretty, but it can be hard to find on a cloudy day.

There are two at our field and I have one getting close to flying.

You're dead on about the visby thing ... both members flying them have added lots of red and yellow to their planes. One has a neon orange leading edge that really stands out now. They conplained that it got hard to see in any weather when it was head-on or tail-on. It's got a small area showing coming or going.

As far as flying, they love it. One of them is competing in Sportsman class pattern. He's had a F3 guy fly his plane and the guy said there's nothing wrong with how it flies. It's a good intro to pattern.

Flight characteristics are first class. I flew mine with a YS63 to practice Sportsman & Intermediate, which it does beautifully. Covering is OK as far as fuel-proofing goes, but visibility was not to my liking, so I strippped it right out of the box, recovered wing & tail with monokote, glassed & painted the fuselage.
Construction is reasonable for an ARF, no joint failures.
