Hi,
I completed my Skybolt back in May. I just got around to flying the maiden a couple of weeks ago. Since I'm still quite new to this hobby I couldn't justify the cost for a nice 4 stroke at the time, which I really wanted for this plane. Instead I opted for an affordable GMS .76 ringed. It had no trouble pulling around my 10.5 lb skybolt, and seems like a very nice engine for the price. The plane flew very well IMO and only needed two clicks of UP trim. I hope to get out to the field a couple of more times before the snow begins to fly, so I can really try her out.
You can see a short video clip of the maiden flight here:

Also I have a site with some pics of the build here:
