That's correct.  It's not too hard to engineer an attachment for a 50 lb
load.  Even with a 6 g landing or whatever it's only 300 lbs., easily
handled by a 1/2 inch steel rod.  As I recall the load limit on the
neoprene rod ends is about 300 lbs.  If the static load is much higher
than 50 lbs, I will use something else.

Bob,
Of course you meant the rear mount supports 50lbs in a 1G environment
and without additional p-factor forces you might get when slipping(I
think) or when pitching the aircraft and the rear support would be
involved in pitching the motor-drive-and-prop(the faster the more). Tom
