Whirly, Tigers dont have flaps but should be able to recover from a stall in under 300ft with ease. Obviously if you do anything low enough its dangerous, even a turn, if low enough could be dangerous but I still dont think spins are particularly hard although of course they could be dangerous, if low enough, like everything.
What do you mean they froze on the controls? They froze in straight and level, or they froze in a stall or what? Even if they did couldnt you just use your controls to get out of it?
