I have a theory as to what caused the warp . . .

In your pic, the fuselage is completely supported by the launch rail, on ONE side. HOWEVER, the clamps are providing uneven pressure ( at their contact points ).

As a result, they "pinch" the fuselage, likely compressing the foam core, and introduce a "pre-load" to one side of it.

I suspect that the 3rd clamp ( the Black one, 3rd from the left ) may be the "culprit", due to its location, although all uneven clamping pressure is the prime suspect.

Solution : When you build the next fuselage, use even support and clamping pressure on BOTH sides of it and make sure it is FULLY dried / cured before touching it.
