"each of the three" -> maybe rather main gear and front gear as I don't think you can have a fairing on the left wheel but not on the right one ;)

This could be a dialog for this: `<?xml version="1.0"?>

``` c150-wheel-fairings vbox false false true 0.6 0.65 0.55 0.85 hbox true C150 Wheel Fairing Options true

Esc 16 16 dialog-close

vbox left Main Gear Wheel Fairings /controls/gear/main-fairings true dialog-apply left Nose Gear Wheel Fairing /controls/gear/nose-fairing true dialog-apply hbox left

?

nasal right

Close

true Esc true dialog-close ``` ` I don't want to add it as a commit/pull request yet as I'm still pending the pull request for the shadow and don't wanna cause confusion ;)
