Not kidding Paul, only ignorant... Now I remember that BD-4 very hard
landing...I did not know the engine mount was your design. Very
impressive. Thank you for the reading material. Yvon C.

The hard landing didn't hurt the motor mount at all!  It was rotating
the whole plane 120 deg. while going through the weeds at 60 MPH or so.
Probably caught one of the mains on something which caused the nose to
tip down and catch the prop.  Very sudden stop.
