well, i got to fly mine sunday and i can't say it went as well as kwboost's report. only got two flights in, the first the plane was to tail heavy(atleast for me)so i moved it to 4 1/2". The seccond flight was good until i saw somthing shinny fall off and dangle from the plane in mid flight. Then the o.s. dead sticked, thankfully i wasn't far from the runway and glided back down. The shiny object was the pipe, mabey i should have used more lock-tight. I gave up for the day and decided my nerves had enogh for the day. Any way i guse i try again next sunday[&o].
