the R22 and R44 revolve in opposite directions to each other,
the R22 anticlockwise when viewed from the left and the R44 clockwise.
the R44 being the more conventional direction, i heard several reasons why the R22 is like it is, one was that they used off the shelf parts and thats how it was, and another that it just worked better anticlockwise
hard to know what is horse s**t and what isnt
