Planes and Engines that hover...only. Please apply.
I Have an OS 25FX, an OS40LA, and an OS61FX laying around. I want to pull out of a hover with no effort and plenty of power left over.
With all of everyone's experience, which size QHOR would be the best for which engine? I hear some posts that say the 40LA is ok on the .25 size and some say not.
Also, I am at 4000 feet elevation. They don't fly the same here as at sea level.
