     • note: you may be able to try and open the mod file after downloading, but some people may have trouble getting it to open with SimplePlanes, and the way I have written out is more reliable.
     
     

Now in the SimplePlanes designer, near the bottom of the screen, a fair bit to the left of the play button, there should be a new button, click/tap on this button to open the fine tune tool (note: the tool will not automatically close when a stock-SP menu is opened, so you may need to close it manually to deal with other menus).

Please report any bugs you find here with a detailed description of how to reproduce the problem.

Also feedback is welcome.

Steam users: I do plan to publish this on the Steam workshop, but since it's in beta I figured I'd wait a little while.

Semi-Important: Since SP gobbles up any keyboard input that it has bound to something, you can't use the keys it has bound, so I recommend that you go into the controls configuration and in "designer" remove the "backspace" from the delete part input, as well as changing the "next weapon" input (in the "flight" tab) to something other than the period/dot so that you can type in custom decimal numbers, too.
 
Edit: I can't believe I forgot, big thanks to @Skua for the awesome icon for the tool button!
 
Other Edit: here is the version with scaling
