Ok, thanks to all. This will help me.
My plane is like spadet lc40 standard trainer with high placed wing (1650mm wingspan, 250mm chord plus aileron and 1120mm fuselage). Engine will be tt46pro or st gs-45 (I have both new in box received from usa before 7 days - thanks to my friend from ny)
radio for plane is not yet at home, but hitec optic 6 is on the way.

This is short version of my first plane. Airboat is first and this is great stuff

thanks again
