Here is a much simpler version of my multiengine bonanza, lovingly named the V70 (2 v35s). If you are a doctor and want a faster way to lose control, this is the plane for you! the weight and balance is relatively stable and it can be recovered from a flat spin if you cut the throttles and deploy yaw in direction of spin and opposite aileron, and throw the flaps and gear down and full down trim. it can take a few thousand feet to recover but it is possible. I added separate engine controls so you can use 1 and 2 to turn the throttles off for each engine to simulate an engine failure. Definitely not up to the standards of certifying Vmc but if you raise the dead and yaw into the working engine it will fly straight-ish. Have fun!
