Buly, I agree,  for your situation, the misting may be just the ticket.  I 
fortunately do not have any overheating problems at idle or taxi speeds even 
on a hot day, but once the power comes up for take off the temperature 
increases quickly.

Fortunately, it seems that the rotary can withstand temperature excess at 
least for a short period without ill effect.  I have had both my oil as high 
as 210F and coolant as high as 240F back before I got my cooling more 
optimized.

Be interested in the effect of your misting system on your temperatures.
