In designing your own airplane, a few consideration should be taken care of.The very basic principle is the COG or CG also known as Center of Gravity. CG exist in every flying craft and when building your own foamie aircraft, the important of getting the correct CG location is crucial if you want to have a successful maiden and enjoying the rest of your airplane flight.Center of Gravity (CG) is the point where the WEIGHT of the aircraft is balanced. Neutral Point (NP) is the point where the AERODYNAMIC FORCES generated by the wing and tail are balanced. Here are few tips on getting the correct CG for your plane.1) It should be on the instructions of your plane. Whatever it says, its safe to go just a wee nose heavy from that! Then for your next flight, move your battery slightly back and see how you like that. 2) Chuck glide it! If you are building a foamie, before you put all the electronics on it, straighten out the control surfaces with tape, put a small weight on the nose, and throw it over the grass! Adjust the weight until you have it doing a nice steady glide! Now you found your CG and put your electronics on from there! 3) Just guess. Make it what you think is a little nose heavy and just be ready to give your plane some up-trim after it takes off. This is fine, just land the plane, move the battery slightly back, reset your trim and repeat. This is what we do most of the time. 4) CG Calculator Page and Canard CG Calculator Page oh and THIS ONE too. These fancy pages only works if you have a very traditional "wing" and "tail". Remember, on all your foamies your nose and body also count as the "wing" so this locater page is not going to be good for you. We never use this page even though its very popular. 5) Benefits of Tail Heavy Moving your CG farther back will give you more maneuverability like we did with our Wild Hawk and out Su-35 (just scroll down the pages). A gyro is greatly appreciated to help keep the plane steady doing this as the plane always wants to flip up!

| Before you run your RC: Controller on first, aircraft on second. Never turn your RC airplane or helicopter on with your controller off. Another controller in the area may take over and fly your airplane or helicopter into a tree, a power line, or right into the ground. |
