Concern over cicuit boards on the wing flaps and aierlons ect are under load , but trama like a landing gear oloe takes , and like rails take from a hard landing . You said yourself that the 615 failed on you during some of the landings I know you are one of the most competitant modelers on the net , that is why I am expressing concern over circuit board controls in high stress areas .
Even receivers are usually buffered from vibration ect , the lados will not be able to be buffered , again , I like the gear and hope they work and last but just expressing my concern
