Hey foresterxt you are right about that Up-roar arf! I got one when they first came out, with the sale price and other discount it was practically free. Its a good quality and great flyer. Also the OS 40 la is a good little engine, does well with a 11-5 prop. For all the folks who have one of these engines sitting around build a Sig LT-25 and put it in that. A top quality lazer kit that is a joy to build, even a caveman could build it. After flying your high performance planes its fun to do touch and go's with this plane. Have fun!
