=iff compare AEROPRAKT A-22 /A-32 systems=my Fellow prefer to fly A-22 yoke mode
(A-32 have better parameters!)...=probably long cardriver practice ?
-I personally like motorcykle like system=
(at the end=two halves of "bike" controllbar )
-or simpler, "SILENTGLIDER" (one rotating bar).
Why not? For sure they are some pilots prefering unusual control systems.
But young pilot really needs to build flight experience and knowleadge on airplane with standard control lines. It makes no sense to let young pilot to fly with not standard controls. After building flight experience he must have opportunity to fluently continue on competition gliders or on airplanes in higher categories to obtain PPL, CPL or ATPL pilot license.
Experienced ultralight pilot flying with ultralight (LSA) airplanes is able to make easily PPL license.
Pilot trained on gliders like L-13 Blanik must be able to fly simple e-glider with minimal time for conversion. Every difference in control lines will make conversion difficult or impossible and also CAA (FAA, LAA...) inspectors will not like it.
