I have no idea how this has ties to the bush plane but yea it does.
Someone from my large bomber post requested for me to make a regular bomber. This one was much more easy becuase i didint need to do the turret unlike the large bomber.When bombing, i made it so you can choose witch method you would like. Either using ag 4 or the traditional a to g mode. If you have any issues flying this, please let me know in the comments.
Here are the controls:

Ag1-engine
Ag2,3-nothing
Ag4-drop bomb

Im gonna make the torpedo bomber next.
(Note: when using the ag4 method, please only bomb structures and not ground, otherwise it may either not detonate or clip though the ground).
