Need some identifying this old pattern plane please.
 

I think this is a .60 size Super Kaos with a fiberglass fuse, though that dorsal spine leading into the fin throws me off. Tail doesn't look right either, but may have been modified. What do all think?http://www.rcuniverse.com/forum/atta...mentid=2159820http://www.rcuniverse.com/forum/atta...mentid=2159821

Yes, modified SK60. The tail looks right except for the dorsal keel and different canopy from the original SK. The canopy design might have led to the keel given its height at the rear.

Thanks David. I've looked over a bunch of Kaos's, and I've seen some with that spine, but not so severe or tall as this one.

The wing looks rectangular. Could be a photo illusion.

It looks like a Dirty Birdy canopy. The additional fin area was frequently added to the Super Kaos when they started being powered with schnuerle ported 60s. Much more powerful than the older cross-flow engines (OS goldhead, blackhead, K&B, etc.) and the tail would oscillate at full throttle. Also known as the Kaos tail waggle.
