It took me over 14 years to make this mistake but my time had come . I was going to test fly the ultimate ,started down the runway and on lift off the plane started to bank left so I added right input, it did a nice 360 roll then a hard hit removing the pants ,gear,cowl and top wing split on the glue joint. Yes I hooked the servos up wrong. I repaired the top wing , and gear I"ll try again when the weather changes.
