I have duplicated stall conditions with other planes on realflight, even a jet (It was a King Cat? that a user crashed, he had posted the video), so I'm sure it can be duplicated.

But, it sounds like you just need to remember the basics, like drop the nose and build up enough speed to pull out (or have enough engine to power out). 100ft should have been plenty of room to recover.

The fact it went down in a spiral sounds like you had some elevator applied (same as the guy with the jet).
