hello i could use some help! recently bought a christen eagle 65" wing, i powered it with a DA-50, i got it all together, balanced, went out for it's maiden flight and wrecked, here is what happened, at about half throttle the tail rotated up i eased back on the elevator stick, and it started to climb and i mean climb straight up! i had to give it allot of down for level flight, when i would reach for the trim straight up it went again, after about 4 minutes of this the motor died and it wasn't a cool dead stick,. its now back flying but with heavy down elevator trim.
the horizontal stab and bottom wing are spec at 0 degrees, and the top was at 1 degree positive, the motor is at 2 degrease down and 2 degrease to the right.
last night i moved the the top wing to 0 degrease incident, i went and flew it today and it's still flying with a tail heavy attitude, but tail heavy its not after the wreak i moved all the battery's forward.
the mfg told me it was the horizontal stab, top wing, or the motor incident, one of them were off, there not except for the top wing witch i moved to 0 witch did'nt help a bit.
a master builder I'm not.
maybe one of you can help me to understand my problem better.
