Here's Viktor doing a short take-off in his 601 HDS equipped with Feathers VGs
Comments from Viktor:
Lift off speed 38kt. Check the very low movement of the elevator!
Check the high angle of attack during the whole T/O.
Airport elevation 2650ft and OAT 18°C, light wind.  2 persons and 50lt of fuel on board.
Check: High airport elevation and temp. well above standard. The aircraft well loaded and only 80hp.
Main gear lift off and the tail still on the ground, fire under the titanium tail skid during rotation, looks nice .
