The answer is quite simple if you want a plane to fly in masters class or you are a pro class pilot you got to spend atleast 2000$ & up for a good plane... OR the other option is you can buy some cheat 2x2 F3A planes available in the market. What you pay is what you get. Pattern planes are precession aerobatic planes built with great care & time taken is more compared to those giant scale planes. Try building one F3A 2x2 you will automatically get the answer...
