So this thing will be right sized for a Saito 91?

I'm with Wagas. I go about 1/2 and 1/2 kits and ARF's. I prefer kits, but don't have time to build all kits, so I also have a few ARF's. I had a couple of bad ARF experiences to start with and still have had only what I would call 'fair' quality ARF's. Remember, these planes are being measured against what I build, a tougher yardstick than comparing a reasonable quality ARF to a POS ARF.

But forced to go one way or the other, I'd be a kit man.

I am also very interested in the ARC method, but this just doesn't seem very popular.
