I couldn't get rid of my trainer fast enough (noone wanted it and i didn't have the room for it)...once i saw how the UCD, Funtana and other 3D machines flew i knew thats what i wanted...my UCD comes in for a landing even slower than the trainer and with a Saito .82 it lifts off in about 15ft. All the trainer really did for me was get me interested in this hobby and now i'm hooked.
