Human Factors
While doing touch and go's at Ryan airfield (RYN); I was cleared for a touch and go on Runway 6R; as I was approximately half way on final there was an experimental aircraft on 6R taking off (it may have also done a touch and go); as his speed appeared fairly slow; the tower then requested I sidestep to Runway 6L which I did; upon touching down and then proceeding upwind (at approximately 300-375 ft AGL) I came into close proximity to the experimental aircraft who had turned making a left crosswind departure from the pattern (6R is a normally right hand pattern and I do not recall if the experimental aircraft had clearance to turn left); I then diverted down and to the right to avoid what appeared would have been a collision; recovered and continued upwind.If the tower had given the experimental aircraft clearance for a left turn; and then instructed me to change to Runway 6L; they might have; at that moment forgot (I think that is unlikely) that I was doing touch and go's (although I had been in the pattern; doing touch and go's; for approximately a half hour prior to this occurrence); they might have thought that the experimental aircraft would being moving faster than it actually did; hence they might have believed it would have cleared Runway 6L prior to my climb out; which it did not;I believe what caused the situation was a lack of awareness by the tower as to the speed of the aircraft involved and where they were at that given point in time. I think great care must be exercised when a nonstandard movement is authorized (assuming it was) from the pattern; especially when parallel runways are involved with simultaneous takeoffs taking place.
GA pilot reported a NMAC with turning traffic climbing from the parallel runway at Ryan Airfield.
