Jucava,

I'm flying my Eagle at the rear most recommended C.G. location and it handles great, no snapping tendencies at slow speeds, and it flat spins well with a nice recovery.

Warhwk,

I have a Moki 2.1 with the Moki radial mount and a Bisson Pitts muffler. I installed Nelson scale flying wires on the tail, but the radio setup is per the manual. The C.G. came out perfect using an APC propeller. I do not fly mine with the main wing flying wires installed, but that does not effect the C.G., just the overall drag of the airframe.

Initially I flew with a wood propeller and the C.G. was almost 1/2" behind the recommended location. It flew fine there but it did not recover from inverted flat spins well. I thought I had lost it the first time as it would not recover when I neutralized the sticks and the spin finally started to slow down after 2 turns with opposite rudder. I had to wait for 4 full turns for the spin to stop before recovering. Needless to say, I used up a good bit of altitude.[X(]

The only thing I would change about my Eagle would be to reduce the incidence of the top wing. My wings are set up with the bottom wing at minus (- 1.0 degrees) and the top wing is positive (+ 1.5 degrees). My best guess is that the top wing should be zero (0 degrees) or positive (+ 0.5 degrees) maximum. I believe the Eagle would perform some of the snapping manuevers better with the reduced incidence on the top wing. When I first installed the wings the incidence was: bottom wing positive (+ 1.0 degrees) and the top wing minus (- 0.5 degrees). Those numbers didn't seem correct so I checked the G.P. website to find out what the incidence should be and set it up accordingly. The changes where a nightmare to make, but the Eagle handles well so I haven't touched it.

My Eagle wheel lands best. If I try to make a three point landing it tends to bounce up a foot or so, making for some wild landings. If I make a wheel landing and stick it with a touch of down elevator the Eagle handles very well, and still slows down in short order.
