RE: Which one is less forgiving?
There are more ways than one to skin a cat. Actually, let's say, there are more than one cat to skin.
See the picture of my two almost identical 46size Tigers? One isn't a Tiger2.
The Tiger2 in the picture is the ARF and weighed in at 5lb 13oz ready to fuel. That's not a light airplane for that size, nowadays.
The airplane in the foreground is a KYOSHO Calmato Sport. It weighed 9 ounces lighter than the Tiger2 when it was first rolled out. Just over 5lbs is better than almost six.
The Calmato can be gotten in RED, BLUE, or that yaller. They are truly almost ARFs. The surfaces are hinged. The hinges are glued in, that is. The control horns are already installed. The motor mount is screwed to the firewall. It's really close to actually being an ARF. Mine was one year old a couple of months ago. In that year and a couple of months, I had to do one thing to get it to last that long with almost no maintenance. I ironed it all over the first time I touched each part. KYOSHO's need to be ironed out of the box. Do that and they give no problems from then on. The P40 in the above picture is a KYOSHO I got a month after I built the Tiger2.
I've gotten both my LHSs to order the KYOSHOs I've built. It takes either one of them about 3-5 days to get them.
