Here's a pretty good thread on the subject: [link=http://www.rcuniverse.com/forum/m_3606334/tm.htm]RCU Decathlon thread[/link].

FWIW, I had one, and it WILL tip stall if you get too slow and try to horse things around. I had my CG at about 90mm also. In calm weather, landings are a cinch, but I found myself in trouble more times than not if I tried to chop the throttle and glide in. I found maintaining a bit of throttle and flying it to the ground, using elevator to control speed and the throttle to control altitude, worked better, especially with some wind. On my last day with the plane [&o], we had about a 5-10mph quartering crosswind, which I had always found difficult with this plane. I practiced several landings that day, using more throttle as described, and found it much easier to land. I had the crunched right wingtip to prove the tip stall tendency; I had done it 2 or 3 times from low altitude, trying to land in wind or deadstick, and using too much elevator and not enough power (obviously had none in the deadsticks). Point is, don't try to stretch a glide, and use power to adjust altitude, more so than elevator input, and you'll be fine. I really enjoyed this plane, and plan on getting another this winter, as it is a wonderful looking, scale-flying plane that is relaxing and enjoyable to fly, once you know it's tendencies.
