I have now successfully flown my gyro shtick with your blades fitted, took a little bit of trial and error with control inputs but now flies nicely. I have attached two photos, the one with the pilot (me) has flown, the other awaits its first flight. They are powered by emax 2810 motors which have to be mounted further to the back to balance the gyro properly, they have 3cell 1500 lipo batteries fly on half throttle.Keep the faith.
