Tomi,
Good news!

We went to Bomber Field and the rep for Cedar Hobbies was there selling these kits. He had a "show special" on the 40 size Stick and one of our flying buddies bought one for $65 bucks.
Here's the good part for you: I loaned my buddy my "collector" Super Tiger G-21 series .46 (Old style small case with the ST flow thru muffler) to put on his newly aquired Stick. It weighs a tad over 5 lbs. and goes like a scalded cat on this old engine.
(Collector motor?............ I got it when I was in high school in the late 60's. It came in a beautiful new, unflown R/C Nobler, scratch built, tissue and dope finish, etc. Some old dude brought it into the hobby shop to sell. When I told him it was the prettiest monkote finish I'd ever seen, he kinda snapped at me and told me it was 30 coats of hand-rubbed dope! (Monokote had only been out for about 6 months) I told him it was probably way too much plane and cost for me to handle. He asked me how much I had on me and all I had was $100 dollars in lawn-mowing money. He asked me for the money; I got me a new plane with one of his custom motors and we both went away smiling. The old dude? George Aldrich, Supe Tiger expert, designer of the Nobler control-line plane and one of the nicest modelers you'd ever meet!
Get the plane. Put your .51 on it and go bore some holes in the sky. I checked this one over and the landing gear mount and firewall seem to be well glued. The green covering appeared to be good quality stuff. I'd move the aluminum gear forward and bend it downward for a little more prop clearance. (Using an APC 11-5) Plane jumps off and moves smartly about with this combo. Lands slow. (Come on....It's a STIK!!) Enjoy!
