The simple method of figuring out the CG is follows: Measure the wing cord at the fuse & write it down. Lets say its 12". Next, measure the wing tip cord, and with that down, and lets say that is 8". Now you need the average of the two which would be 12+8= 20". Divide my 2, and you get 10". Now find the point on the wing where the cord measured 10", and that becomes your "main cord line". You never want your CG at 50%, which would, in this example be at 5" back from the leading edge at the main cord line. Say you want more of a trainer like plane, so you would multiply the main cord number of 10, by .28%. That gives you 2.8" back from the leading edge at the main line. If you want more of a free style, or aerobatic flyer, you might go as far as 40%. Now multiply that 10" by .40 and you get 4" back on there main line. That now is your CG for a more aerobatic plane. Now you will need to either move the battery around to get the wanted CG closer to the where it needs to be, then you need to add some weight so the plane will balance in the correct CG measured before. Long story short, your now CG range will be from 2.8" giving you a more easy to fly airplane, to 4" which will give you a more aerobatic airplane. Remember, this is the simple way to do it. It can get really tricky with pipes, or other unmentioned aircraft we have in our great hobby. This formula has worked for me for over 40 years building & flying RC. Good Luck!
Wow!!! I'd love to have something like this in the future.
Nice!!! What is the maximum speed of the airplane?
I have the same plane. But i struggle with the CG. Where do you have the CG ?
