Sorry to hear about your ugly moment, man.....[&o] This is one of those sports where 99.999% perfection still sucks....

I've straightened pipes by making a close fitting bar with a rounded end that could be slid into the pipe.

From now on, take the time to do a full range check with a new plane in your arms and the TX back in the pilot area. Walk the entire area where you intend to fly. You might be surprised with what you find out if your field is in a noisy area. If the controls budge or jitter just a little bit, then you can consider what happened today something that might happen again if the field itself has interference.
