Last time I had the H in the air I was raising the landing gear and noticed it wasn't moving. I thought maybe it was just me or the (USED) controller I received back from the repair people. Checked the button in the hardware screen, and it works. flipped the H over and flipped the switch and it makes a noise and moves about a half inch on one side but doesn't retract PERIOD!!! I have it to where I can use it now but I still can't retract the landing gear. My fear is sending it off to be repaired only to not get "MY" aircraft back, like they did my controller. So would it be better to just order the landing gear and put it on my self (sic) or should I take another chance with the Customer Service/Repair people??? This is the second problem I've had with it, I love this bird, it is less than a year old (march 2018) And sitting on hold for 1 - 2 hrs with CS what to do? Suggestions would be appreciated.
