Hello Guys
i am in the process of building my 1/4th scale rc airplane which looks like a sig rascal and it is a high wing trainer and i am using a 33 cc chain saw gas engine with an 18*8 propeller and the goal of my project is to built an rc airplane which is quiet stable in the air and the control response will be nice but after completing the fuselage structure i am a little worried about the calculations of the control surface area on my rc airplane and what control surface area size would be better for a nice controll on my rc airplane
so guys please tell me that how do i calculate the control surface area on my rc airplane like ailerons,rudder,elevator etc
the specification of the airplane i am making are as follows
wing span 8 foots
wing width 18 inches
fuselage length 6 foots
gross weight 7 kg
wing loadings 18oz/sq foots (aprox)
