I'm building a balsa kit, and I ran into an issue. The manual calls for a 3" spinner, so I got the hangar 9 P-51 style aluminum spinner. I also got the power 60 470kv motor from eflite, but I cannot seem to find the prop adapter I need. The one that came with the motor isn't long enough for my master airscrew nylon prop and doesn't have threads for the spinner. I looked all over horizon hobby and can't find what I need, and when talking with them directly they can't find anything either. Any help?
