Hmmm, just happened by here ... been flying R/C since 1973 and never once have I heard the words "good-flying Decathlon." Makes you wonder why the manufacturers keep pushing them. A friend of mine even made a profile electric park-flyer version out of Depron -- it looked great, weighed nothing, still flew terrible. The tails on them are just too small and too close to the wing.
