landing gear transition on takeoff

[Roger]

Buy some electronic cleaner in a spay can (it's like brake cleaner, only you can use it on electronics). Pump the doors open and spray all of your door switches and locks. Then blow them off with air. That should more than likely fix it. I am however surprised that you have to ask the tower if your doors are closed. You should instal a mirror or two so you can always be sure. Good Luck
