Need help with an airplane

2 goldenpeach  7.2 years ago

Hi!
As the title suggest, I recently made a plane which, although it can fly, have the tendency to go out of control too easily.
So far, the only "solution" I have is to have a bunch of parachute at the rear of the plane that I can deploy to regain control.

Anyone can help me?

Thank you in advance! :)

    In the builder menu, click on the tool that looks like a scale (a triangle balancing a line and three circles). You'll see two vertical lines on your airplane, one red, the other blue. The red (Center of Mass, or CoM) line should be a little bit in front of the blue (Center of Lift, or CoL) line. If the CoL is in front of the CoM, or even if the CoM is only barely in front of the CoL, your airplane will be unstable or will not even fly at all. There are several ways to shift the CoM and CoL lines, the easiest two methods are simply to add fuel or ballast forward or back on your airplane...the resizable fuselage has options to add both of these--be sure to never use the default fuel tanks, they are far less flexible than using the resizable fuselage part. Anyway, adding fuel or ballast to the forward parts of your airplane will shift the CoM line forward (the inverse is also true). You can shift the CoL line by shifting the wings forward or aft on your airplane, or even by increasing or decreasing the size of your wings.
