The question only mentioned wind, so perhaps more than you wanted, but changes with density altitude are noted in several threads.  One here

MAH and speed can change unless rpm changes are made to compensate.

Same for glow engines. Been flying my Banshee in strong wind with a Brodak 40 and wow does it have more power.
