HK Icon A5 first attempts

Without the wing floats taking off from the water was not possible, hence the start from the grass. The plane is a bit tail-heavy, that's why the landing was a bit shaky. In the mean time I've put the wing floats on and added more weight to the nose and the results were much better (including taking off from the water). I'll post a new video some other time.

Nice flying. I have the same model. Using the recommended CG (55mm back from the leading edge) I find it quite difficult to fly - although I am a bad pilot! It seems to "tip stall".It would be very helpful to know where you have your CG? I read that 70mm is good, but that sounds dangerously tail heavy. May try 60mm. Regards, Paul.

@jpaulgood I have the CG at 50mm from the leading edge now and haven't had any tip stalls since. I do think the CG should be even more forward. This airplane does become unstable with strong wind and also during some maneuvers I notice it should be better to move the CG further forward. This plane has a large dihedral so it really must not be tail heavy. I'm planning to move the CG to 45-40mm from the leading edge for the next flight.

@jpaulgood Thanks - I'd be very interested to hear how it flys..I am sure you are right about strong winds. Definitely a fair weather flier! Not yet tried to take off from water. Do you recommend fitting the wing floats? How easy is it to control on water?
