Yes they are!! I will be putting another one together as soon as I can afford too. In the meantime I just got back from Maidening my little WM Ultimate 40.
All I can say is WOW!! What a sweet little plane this thing turned out to be. I spent many hours trying to get all the throws set up mechanically as close to dead nuts as I could so that I wouldn't have to rely too much on the radio to get them trimmed in right. I missed by one click of down elevator.[&:] After that it flew perfectly straight & level @ half throttle hands off. What a pure joy it was to fly. It took all the sting of losing the Cap out of me. I flew at least 10 tankfulls one right after the other. I don't remember when I've had so much fun!! It was so well behaved I just couldn't get enough. I haven't giggled like that since I soloed. I love this plane, it's my new favorite flier for the moment.
