Zippi,
The Brillelli 26cc engine should be a better engine that the 25GT engine for the Giles. I know it has a little more power and is a little lighter. I'd like to see a video of it once you get it installed and flying. I was lucky to have someone at my field who wanted these 25GT engines. It made getting the 40GT and now the 54 when it ready a lot easier on the pocket book and with the wife! I am thinking the Giles-202 with the 40GT in it will fly a lot like to Wild Hare 73" 540. It will have a little more wing loading, but I think the Brillelli 49GT engine will make up for it.
Scott is sending me some decals and I ask him to send a couple more for you. If I get them I will forward them off to you. I still might get the smaller ones made for the fuselage.
