Hi Rev.
I am still on the 3Blade set up,and will probably go back to a 22 x 10 3Blade as I know I can get around 5400 to 5600 ish then richen..I have done more ground runs with the 22 X 12,but at best only 5000 to 5200 Max....still think that this will be enough to try after the maiden with the lower pitch 3 Blade prop.
What exactly broke on the "robarts"....? A few issues with these at the moment...mine still in the box with the wheels on !!!
As Cristian asks.....what did you think of the power available..?
Regards....Nick (UK)
