A fast flying heli will always have a bank angle. Why? A rotor blade produces lift proportional to the speed dof the air around it. When the heli flies foreward, the blades that are also moving foreward (on a clockwise rotating rotor the left side) are producing a higher lift than those that are going backwards. The resulting force will create the bank angle you've experienced. (Or mechanical: the center of lift moves to the side. And the center of gravity -which is fixed- will always be in a stright line below it. So the heli will bank untill these centers are aligned again) CU, Christian -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (MingW32) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFB4BellhWtxOxWNFcRAvi8AJ4rNxSIFL4EuDIvq1BLmwCYK6Y/9wCgmdrT UVhetUB/OqVCxRLTdY2a3U4= =B8g6 -----END PGP SIGNATURE----- _______________________________________________ Flightgear-users mailing list Flightgear-users@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-users 2f585eeea02e2c79d7b1d8c4963bae2d
