And this(stall REVIEW) is good advice to FAMILIARIZE yourself with this type of maneuver

This input/analysis is in support of the good flight training advice provided,

        but here's the punch line:

 Never try this in a Lancair without a parachute, or at least not in the IV-P, with which I am only familiar. I theorize the (big engine) forward of cg weight distribution and what Burt refers to as "not enuf tail", may cause an irrecoverable flat spin. I think this aero/mechanics theory could be simulated by a good undergrad Aero E. The scenario is that too much rotation mainly in yaw (probably coupled from high roll rate at initial snap roll departure) in the departure/ incipient spin, causes centrifugal force to pull the heavy IO-550 engine out from the axis of rotation. Then, either aero blocking of the vertical stab/rudder(as in the A-4 inverted spin) or simply not enuf surface area, leads to a flat spin. Same factors prevent using horizontal stab and elevator to recover. Now only option is parachute- but I can't figure out how to get the (IV_P)door open even in normal flight much less this odd force distribution.

 Please practice this maneuver(extraLNC), especially in a small Cessna or Decathlon- {some 8KCABs have twisted the steel airframe in the longitudinal axis doing this- you can see it on the ramp, if you examine closely on preflight. and feel the trim error in flight .}

 Exploration of the NTSB data suggests it is usually SD: spatial disorientation(which can surprise, in VMC, with the right combination of unanticipated forces and panic) and these departure spin characteristics that have caused the sad statistics. It's harder to modify the hardware, but we can add warning systems for both problems, but as is always the case, the least expensive and practical solution is to educate and train the operator

Be safe y'all
