thanks

In fact in my Kyosho Calmato trainer manual it says 12x6 propeller, but I went to buy one yesturday and the shop advisor told me it won't turn correctly on your OS 46AX engine...
Hey i see you are running the same set-up as me. Kyosho Calmato trainer with 46AX. I tried the 12x6 prop on for size and i wasnt comfortable with how close it was to the ground. with my landing skills

i need some clearance there. I learnt with the 10x6 all along and now switched to 11x6. The 46AX seems to a lot happier with this and sounds really smooth.
BTW, did you buy yours at HobbyCentre?
