MX2 taking flying lessons from the Cubby?

I had spent some time strengthening the attachment points on the elevator and ailerons, and putting CA hinges on the MX2 and was pretty excited to fy her today. Checked CG, everything looked great. Took her up the first time and the engine quit on climbout. One of the motor wires came loose. Managed to almost get her back but she landed clean in the blackberry field. Trouble shot, fixed, took a moment to change the landing gear position. Took her back out. She flew like a pig, barely climbing out with a lot of oscillation, powered her to altitude but she wasn't controllable. Barely got her up, had trouble turning her around, and as she was coming back she rolled uncontrolled and dived into the ground, ala Cubby. So I spent a couple hours flying pack after pack on the Alpha practicing cross wind landings.

Yup, MX2 has been taking flying lessons from the Cubby.... Need a prop shaft, other than that I should have her up in a day or two!
