Hello, I have a doubt, assures me a friend that the suggestion of engine power that comes in ALL plans for construction
it is made with respect to sea level basically, and then other parameters are used. I think maybe on some planes, but that's usually done taking into account, NACA, weight of the plane, wing position, wingspan, etc. and not the sea level reference, I have flown many years both at sea level and as many at 6000 feet and I know what height affects airplanes..
What do you think about ?

Your Welcome. Now that the discussion is in the proper area I'll say two things here;
#1, I've never flown a model airplane at 6000 feet, Hell, I'd be surprised if any of my flights ever exceeded 2000 feet.
#2, On all but the simplest RC trainer model planes, I've always stuck with the upper end(or maybe slightly above) of the engine size recommendations and haven't had problems with an under powered plane yet.

Hi, regarding your point number 2, I usually do the same. and referring to his number one point, I was referring to the height above sea level. Mexico City is 2,400 metres (7,200 ft) away. I currently live in Guadalajara City, which is approximately 4,800 feet away.

I live at 5200" altitude and have flown a float plane off of a lake near here at 6100". Power is one part of the equation. Using more nitro helps, where many sport flyers use 10% near sea level, the normal here is 15%. At this altitude we use less prop as well. Needless to say, we pretty much tend to the upper end of the power recommendation with our planes.
