i've given up on the Tower .75 (read my thread if you like)........................i should have bought the OS.75AX to start with.
i need an engine that isn't a "dead stick queen"................and the OS is it.
question is, through the search i see people using all sorts of props for this engine.
Bax says that OS recommends prop sizes based on noise rules in Japan.
the list shows 14x6 thru 15x7............but i'm thinking around 13x6.
i will NOT use APC for reasons i've witnessed, so my choices will lie in the wood prop selections.

thx
