Neat hinges. They should allow you real easy access to your battery and keep the hatch in close proximity to the model.
My Bee's first battery hatch is about forty miles from our house
Controls - put rudder and ele on your right stick, throttle on the left, if you fly mode 2. I don't fly as much as I'd like these days and occasionally find myself wondering why the Bee - my only three channel model - won't turn on the ground when I waggle my left stick sideways... But that's no real issue, once I wake up. I could mix my rudder channel (left stick) to my right stick so I could operate the rudder like on a four channel model, but feel that's getting out of hand.
