The drive shaft would have been a real problem as it was in the P39
originally until Alison and Bell worked out a solution.

-----------------------------------------------------------
Another fatal flaw is the swept forward wing box spar.
This puts a torsional load on the spar carry through
that will cause the wing to flex in a vary unstable
manor. Particularly if the carry through is made from something
other than carbon fiber. A wood spar would be fatal as
wood has very low modulus of elasticity.

The tip of the wing will tend to increase in angle of attack
at high lift coefficients setting up a torsional flutter mode.

I also see no means of cooling the engine.
