I don't know how the quality of this plane is but I don't think it is too overpriced if you are getting a real monokte covered, laser-cut, light strong arf with hardware. The GP yak is 400$ from tower and they are probably about the same size as far as weight and materials to build/labor/etc. I think it a good size. I would love to have an ultimate to strap a 180 4 stroke on and have a good 3d plane. My comments are all contingent on the plane meeting the requirements I have stated of course. If it is a chinakote covered, heavy pos with crap hardware and not much pre-assembly done it is way over-priced and should be thrown in the "don't ever buy" category like the 350$ OS 81a.
