Yes, you are right.
Its a perfect 16 Hz Oscillator.
When I touch the FC less vibs, when I hold strongly the Wing which is oscilating at the back, no shakes.
GPS on top or not doesn't change the frequency.
Same reaction with hard mounted FC.
When I hold the wing in the hand at the props vertically, a few shaks and normal, but hard, nervous and hypersensible, reaction of the Elevons.
The few shakes are after moving. The Q System seems to be at the limit of the oscilating system.
But when put carefully on the ground it starts to shake. The back, where at a Nuri the motor ist mounted, +/-10mm.
The whole wing is shaking because of the velcro fastener which hold the wingtips acting as landing gear.
Horizontally in FBWA
I can move, hit or shake the wing with absolutly no shaking elevons. Just smooth corrections according to the direction as expected.
Verry bad, the only one day with good wether since long time and bad wether anounced for the next few days:confused:.
