I'm fairly new to RC, but have logged a lot of time over the past 8 mos on trainers such as the Sig Seniorita.

I read a lot about aircraft that tend to "spin" easily. Based on the posts, I've gathered that this is the airplane spinning while fairly flat (I think). And apparently, it is hard to get out of and often leads to crashes.

Can someone shed some light on exactly what a spin is, what causes them, and if you can or cannot get out of them? Can you spin a 3 channel trainer?

Thanks much.
