Narrative:

On training flight with a foreign student. While on the first departure from runway 26 just prior to turning crosswind, the second aircraft in question came into view off the r-hand side of our plane going the opposite direction. Apparently, what in my estimation was a very close, tight downwind for runway 26. We had to snap left to lessen the closure rate. The cause, in my opinion, was a lack of correct radio usage together with a non compliant traffic pattern in accordance with the aim and applicable FARS. As it turned out, the other aircraft was plted by a piper cherokee pilot based here at redlands.
