Thanks Steve.
I visited the LHS this morning and picked up the MAS props. They do appear to be a bit more "flimsy" than the APC, however they fit in the Dubro spinner - which is what I was looking for...
For what it's worth, I checked out the 2.5" Dubro spinners while I was there and the APC prop didn't fit into that either. [&o]
I figure since this is a trainer and props aren't really all that crutial as compared to other aircraft that I'll fly the MAS and see what they're like. If I want to go back to the APC, I'll pickup a prop hub and have at that. I'm sure this isn't the last visit to the LHS for props ...
Thanks all!
