That's cool mnrcaerobat, thanks for sharing that with me. It seems there is many ways to build, modify, power a Wonder. I'm going to power mine with a TT GP.15, should be plenty for me. Some like to really overpower and just see how much motor they can put on. What ever turns you on, and whatever you have on hand. Took me an hour to do the primary wing construction up to the sheeting of the leading edge and trailing edge. Going together just fine and I'm enjoying the build, more that I thought I would. Really getting into this little plane. Should be a blast. Thanks Brian.
