I don't know if this will save $ yet or cost me more, so I decided to start a new thread.
Experimental

I have been looking at the head design on the LMH and other than getting a more solid boom strike I don't see why I need for the blades to hing down. Maybe the design makes sure we only BUY LMH blades from LMH.
Good or bad I put a screw in the blade so it can pop up but will not pop down. Will keep you posted. only the next crash will tell.
