don't feel bad...I did that on a Magic Pattern plane when I was like 12 years old. Forgot to check it and punched it right in on takeoff. Webra 61 speed, retracts, fiberglass fuse all totalled...6 months of airbrushing the paint on the fuse over an entire winter gone to waste.

Yours doesn't look as bad as mine did. One thing I can guarantee you though after this. You will NEVER (AND I MEAN NEVER) make this mistake again. I check control direction on every flight ever since that crash in my younger days. It made a big impression on me (and in the field).
