Well if I read correctly in that other forum, a fellow ordered a kit (thinking it would be the balsa kit because that was all that was mentioned on the website) and when he recieved the kit, it turned out to be all plywood with no rhyme or reason behind it. he then proceeded to build it and it came out over 2 pounds heavier than stated on the website...gee I wonder why, plywood perhaps. The manufacturuer told him nothing to that effect according to the forum....so even though they offer a balsa kit now, I am still leary about persuing it!
