?? Acton?? is that hwy14 south of palmdale/Lancaster? or I 15 area. don't remember. But most two strokes worked well in the areas of Big bear, Running springs and Silverwood lake. Maybe if You flew up there regular You would try differant props or fuel/nitro percentages But we flew there on accasion (snow skis on main gear) and did not notice any real power loss.

HMMMM? now I got to look at a map
