anyway, the wheel pants as far as I know are not supplied in any profile ARF
from other manufacturers and TMPro are the only ones who added them.
If flying on high grass than offcurse it will be better not to put them on.

We have been reported by some pilots that the SFG, if installed with the long part down
balance the airplane in high speed better...
If you using them, try both directions and decide what feel more comfortable to you.
