ChiSau If you're on the ground and suddenly find yourself facing the other way, or you've spun round 360 degrees - that was a groundloop.
FFF Impressive stuff! One further point.
If you're heavy-handed with the throttle, it's easy to ground-loop a taildragger with a powerful engine (even without a gust of wind) on tarmac. It's important to apply throttle gently when moving off
eg in a Harvard, Yak 3 or any other more powerful warbird.
It's not a pleasant experience, you look silly ( Sod's Law is that there's always someone watching

) and few people make the same mistake a second time!
Been there, done that in a Harvard, got the T-shirt etc.

Hope not to repeat the experience in the Yak!!
