I never flew the Cougar....and I don't know about acrobatics on these little babies.....their mainly just fun speed /sport planes.
I certainly wouldn't try to snap mine...it's goin' too fast. And their not gonna tumble....they fly like pattern planes....on rails.
Razor......want a tip ? Start buying.....the Cermark .40 size has been out of production for a couple years now, and the .60 size is out of production now. The remaining stock...is it !!!
The DC .40 size is still available.....but you know how that goes.
Look at the Patriot...everyone still wants one. ( I have a Patriot kit in the pile, as well as another .60 size Cermark ).
Get 'em while the gettin's good....if you don't put it up, you can always sell it....
