Narrative:

In process of departure from tus airport with flight of 3 experimental aircraft, given runway heading, my aircraft had a failure of landing gear circuit breaker requiring manual retraction during which time I veered off course by 15 degrees (110 degree departure, 095 degree heading on near miss). I saw the other aircraft as he also saw me and we both steered in opposite directions (as tower also informed us of each other). I feel this would not have happened had I not been distraction by the manual retraction of my landing gear.
