Control line airplanes for crashing?

Never heard of such a thing.

I don't know about crashing them into each other, but there's control line combat in which two control line planes try to cut their attached streamers. You might want to look at

What For You Want to Crash a Perfectly Good Airplane???

Not sure where you can get information on this, but try a search on the web for "round the pole" flying.

The planes are as you said, electric powered and built from a variety of materials including styrofoam sheets.

a power supply runs current through thin wires to the motors. The planes are tied to the pole in the center of the room and are indeed flown as control line models. a bearing of some sort is used on the pole.

Two flyers can then chase each other around the circle, climbing or diving by increasing or decreasing the current through a rheostat.

it's pretty neat. I've seen some pretty scale stick and tissue models flying with this setup as well...

Saw it at a model show here some years ago.

Bouncing about the living room, my then three year old grandson declared himself "a kangaroo". "If you're a Kangaroo, what is Grampie", I ask. His reply:  "you a dinosaur"

This must be it. Thanks a lot!
