Hi
This is a question about real r/c model airplanes. I just moved to La Paz Bolivia some time ago. THis ity is the highest city in south america. They told me that I should by a stronger motor for my plane because of the altitude. In my plane box it said a motor 40 FX but they told me to buy a 46 FX please give me an answer I donot know what to do.
