Thanks a lot, this is a great response. I have flown my DA100 with a Menz 27x10.
When you say 3-blades are heavier, how much heavier? And I can see how it would take longer to spin up.

Have you tried any 3D with the 3-blade? If so, how did it perform? Did it hover at a different throttle setting?

I have std. mufflers, do you think I would get less performance on a 3-blade than you did because of this?

Would you tell me what RPM you are getting with a 25-12 3-blade?

Thanks
Craig
