Can't help with the set up but can offer some safety advise. Have the same BH450SE and it is a hot rod after moving up from a coax a couple of weeks ago. Still struggling with it. Anyway for safety's sake, tape the idle up down with tape and MAKE SURE that you use the throttle hold switch when you are handling the heli. I spent an hour and half in the emergency room last night getting my arm cleaned up and bandaged after the blades ate my arm up. Got careless and started to pick up the heli, had the tx in my left hand and apparently came in contact with the throttle. Doesn't take long to turn loose of a heli spinning up in your hand. Heli rolled over on right side and floundered. Bent the spindle shaft about 35 degrees on one side. Waiting on parts now from KA-PLANES. Good luck and enjoy.
