RE: Boomerang Nano!!!
If I remember correctly, the well covers pretty much go all the way to the internal ribs. Getting deeper covers from elsewhere might not work as there isn't enough room in the wing.
IMO the only options are to leave them off, cut the bottoms out or try to find some narrower wheels (and/or wire legs).
With the wells left off completely, my pro-link gear only just about fits. Fit the gear with the wells off and have a look to see how much room you have to play with (I'm guessing not a lot).
