Engine off, hold down letter "I", hold down rudder trim opposite the spin, try gear down, start one engine opposite the spin.
With part of the elevator/stab gone, you may not have enough authority to get the nose down to get enough airspeed.
I've had the 110G, spit 14, and ta152 stall tail down and never recover even with having 30,000 feet to try every single thing and it's quite possible that some planes could get in that position in real life.
