Just wondered what the pros & cons are of 2 blade props over 3 blades are. I've noticed that most diy/arf kits come with 2 blades however most people seem to upgrade to 3 after.

There was a really good discussion on that a month or so ago. I'll see if I can dig it up.

In general the answer (from smarter people than me) was 3 blades is less efficient and 2 blades is almost always preferable.
