beginers question.

Hi Guys,

Something I don't quite understand.. ( or I'm stupid) If I power up on with the collective the Heli lifts off as I'd expect, then if I give it full forward on the cyclic, as expected the Heli takes off into the distance nose down.. However If I then return the cyclic to its center position, it makes no difference to the attitude of the heli' it just keeps speeding ahead nose down, whereas I'd have thought the craft would at least have returned to roughly horizontal even if its momentum keeps in moving forward.

Any explanation welcomed!

cheers

Ok.. I've just read about roll rates and now understand whats happening.

I assume you mean after lift-off you give it forwards elevator to have it move forwards.. with pitch to give it 'oomph'. At that point you have a heli in forwards travel with a nose-down attitude. Center the elevator and you still have a heli in nose-down attitude; just not giving it any more nose down. You would actually have to give it back elevator to level the nose-down attitude (or make it nose up with -ve pitch to actually stop it)

If it's a flybarless model then the input will stay, if flybarred then the paddles would gradually stabilise the heli back to upright (ish)
