Thanks for the reply.
The BME 110 weighs 3.9 lbs no mufflers.
The ZDZ 80 weighs 4.1 lbs no muffler.
Add in mufflers and the BME weighs just a hair more than the ZDZ only
because it has 2 mufflers.
I like twins. If I can get a twin with no weight penalty, that's a no
brainer in my book.

I'd like to hear from more people that have or have not had problems with a single bolt prop hub.
I'd also like to hear if you had a problem and found a fix for it.

Thanks, Jim
