RE: WALKERA 37
W37
I think I agree with you that there will be a difference whether the flybar is below or above the main rotor.
I'm suspecting it gives better hover but maybe a dropped of performance in terms of reaction speed on turns and pitch control.
Well guess we need to further study on this.

that combo looks great. Finally a CNC head for the #37. But like what W37 says, it's not totally a true head for #37. I guess the vendor must have modified it to fit.
But worth keeping track on this combo. Do post us the results on your queries to the vendor.
