It takes talented hands and some tape. Actually, small hands are all that needed, but the small hands around this house are talented as well.

I noticed that problem when I first slid the motor in to check the fit. One reason I bought the Avia was because I already owned an AXI that was one specification removed from TopModelCZ's suggested motor. Seeing how it fit was one of the first things that triggered my idea they designed the sucker for competition. There is close to not enough room for the wires, right?

You will need some serious tape to hold that wire flat against the inside of the fuselage. And you'll probably need to clean the inside to give the tape a good enough start. Bending the wires to match the contour is required as it will push the tape off the fuselage if there is any memory in the wire that doesn't match the inside contour.
