Finally found your flight test video of this 1700mm Corsair from FMS, but you still didn't show the belly of the aircraft, so I don't know how the finished product turned out. I love the sound, but don't think I want to cut into the fuselage. There is another sound system available from Motion RC that doesn't require any cutting. I believe that would be the ultimate way to go.
Saw this clip on 3 Jan. '15 and the only suggestion I have is get a remote mic for yourself. You may provide good info but you were to far from the mic on the recorder to be heard properly.
***** I'll check them out. I do wonder about the weight are they pretty heavy. I am pushing the weight pretty high right now. Its really heavy but it flys well as long as you keep the power on.
