RE: Prop for H9 Alpha 40
Do as hogflyer suggested about knocking the stupid flywheel off, but I used a larger socket and a smaller socket with a hammer. The engine runs much smoother. Been flying like it this for the past 3months.
I forgot to mention, all the props I used where APC. On towerhobbies they are cheap at $2 something and if you buy 6 you get discounted for one so it's like buy 5 get one free. I'm also using a DuBro aluminum prop nut not the plastic spinner. I hate the plastic spinner's but that's just my opinion. And if you want a colored tip, just paint it.
