Which part is feathering shaft? I don''t have time to disassembly those parts yet cuz my final is next week and also my new parts are on their way. I notice that the servo (the one below the gyro) is not moving a-lot when I push those control sticks, I''ll do more inspection as soon as I can. Also, I'm trying to get a simulation to practice and learn aerobatics, can you recommend a good one? And what cable I should get to connect my transmitter to my desktop? Thank you for all the advices, really appreciated.
