I have the Eolo from Midland Helicopters (
www.modelhelicopters.co.uk). I'm just in the process of building it now, but 2 other guys at our flying club also have them. They were flying it outside the club house last night, and it seemed to be an excellent chopper. However, I guess it depends what you want out of it. I've just encountered a problem during the build of mine though; they've given me 2 lower servo mounts rather than an upper mount and a lower mount. Bit of a bummer, but Robbe will replace missing parts etc without any quarrel (or so I'm told).
HTH.
