Dont use jet Engine and prop at The same time

add a gyroscope and give it pitch and roll range

Thank you! :D @CarsonG1017 @FGW2014 @Chancey21 @ZHUAREVONI

Also I have it fly much better now here

@Chancey21 yes, when built to a huge size and scaled down, it acts the same

add wing parts into the fuselage (without fuel if goes in the tail)

Does a wing with less size act the same?@FGW2014

I always triple up my vertical stabilizers to make my planes more maneuverable and move the COM further back to make it a more well balanced aircraft rather than shoving a bunch of dead weight in the front

First, i use the mod Fine Tuner, it allows you to size blocks, you can make the wings really big, by scaling them normally, then open the fine tuner icon at the bottom of your screen, uncheck the box at says scale mass, then just scale them by half in all sections, it will make the wings look small when in reality they are big, giving more stability and lift at the same time. See if that will work.

You can make it more stable by making it less wobbly.

Thank you all for the tips! :D @AnOlympicWalnut @MrDoolittle @Vuki11

My suggestions are to add more rudders, move the COL further to the back, and maybe add some more power. Remember that the centers (COL, COW, and COT) are key to an aircraft.

Lose the weight in the rear

Put more stabilizers inside the plane and it will be more stable
