Yep,
Power plus crossed controls can equal flat spin.
hoey50, are you familiar with the Beggs/Mueller (sp?) recovery? It would be useful to deliberatly flat spin your aircraft both upright and inverted, perfect standard recoveries, then try this one, as if it works in your aircraft it will recover you from EITHER an upright OR inverted flat OR normal spin.
Basically it consists of three steps:-
1) Release stick
2)Close throttle
3)Apply rudder to whichever pedal offers the most resistance.
This has been shown to recover the vast majority of western aerobatic types, and is useful in that, in an unintentional spin, identification of wether it is upright or inverted can be a problem.
Do some reseach and ask someone familiar with the type (and who shares a common langage with you!) but it may be a useful arrow in the quiver.
