Congratulations on some excellent flying skills.
I have exactly the same RC Chinook, and mine always ends up out of control, and crashes somewhere about the house.
The Chinook in the video rotates one way or the other dependant on the amount of throttle used (as mine does), but the pilot shown is far better at the controls than I have ever managed
The only modification I did to mine was to remove the words 'army' on the sides (with surgical spirit), and add some RAF roundels, from an old modelling spares box
I would like to move on to a larger RC heli, but will have to overcome the problem of my kitten (aptly named 'bomber') attacking my Chinook on sight!
