I can appreciate what you have to say and your plans to resolve the tail heavy issue of your Apollo S. I went thru all of these same issues 10 years ago with a Mythos 125e from Sebart. You would think after all these years they would finally get it right. I think in the end it will be matter of you finding a balance in the combination of motor, lipo cell count/milliamps and the right prop to achieve your goals. Keep us posted.
