Here are the pic's I took of mine that I got in a bunch of parts that I got off Ebay. On the Ka-Planes web site it stated that it was ready to accept the 12mm tail boom from a Trex, but there may be an extra piece that comes with the kit for the comnversion that I dont have as there is no way to put a 12mm tail boom on what I have. Check it out it seems to be very good construction and is very stiff so it could be a great frame.
