RE: Prop size with h.46LA
Hi!
An 11x6 APC is perfect propeller for the OS LA .40 and .46 engines!
I have recommended (and used myself) this prop size for years now for all newcommers in my club.
10x6 is to small for these engines as these engines are made to rew low!
11x7 is a little to large.
10x7 might work if its in a low winged sport airplane but a 11x6 APC is perfect in a highwinged trainer aircraft. Like in a Kyosho Calmato.
Regards!
