I'd like to get into scale helis sometime, but I want a larger one, however kits are very expensive. I've seen a thread or two about guys completely scratch building the fiberglass fueslage and everything and was wondering how hard it would be to do so. I was thinking maybe around a 600-700 size? And the particular model would be like a MD-900/902 or MD-520N with the NOTAR tails. Any thoughts? Tips? Ideas? Thanks!
