Hey i finished it for you if you want me to post it.

@Baldovino or that, problem is you gotta put the first digit or two, add the -, and then the last digit. but it works tho.

@ChaMikey you can simply set 10 and -10. It work perfectly

I can't help but I hope you finish it soon because it looks cool :)

ah youre using fine tuner right? if you mirror a fine tuned wing it will not mirror propperly, you need to figure out the opposite angle of the wing. example, if you put the dihedral of the right wing to 10* you need to put the left one to 350*, a bit of math needed there, hope it helps!

Have you used Fine Tuner or Overload? THIS can be the Problem ... I have them myself sometimes XD

@Liyicheng my guess Is your computer is having problems calculating it both the placement of objects from one side to the other and whether is would snap to the chassis of the planet. This is not your computers fault but the program itself. Program having rules that the computer must follow.
