I've been flying heli's for several years, but thought I'd see what these "planks" are like, so I bought an EasyStar.
Having finally built the thing; checked it's CoG, and got the radio set-up, I took it to the field. I'd say the breeze was fairly steady, and only about 5mph, so I threw it into the air on full throttle.
Boy, what a handful! Are these things normally so uncontrollable? It was all over the place!
Needless to say, it's now about 5mm shorter than when it took off, but it survived :-)
I tried several times more, but with similar flight style - what am I missing? (Cue the humour!)
