Prop size on TF Nobler with OS46FX
By the way- since this is in the "beginners" forum - for all you beginners out there, this is not a beginners plane! Its a tricky kit to build, highly acrobatic and very fast! But for those that have already mastered their first low-wing, have building experience, and want a small plane that flies "big", I think that this is a good choice.
