Hi guys. New here. I built a Berkut airframe many years ago and sold the mostly done airframe (past history). I was cleaning out a closed recently and came across a box and it has all the construction videos that I had put on DVD's. If anyone on here is interested, I will send you the things just for the cost of shipping. And no, I am not a scammer.....I'll talk on the phone/facetime to confirm. My cell is 317 407 8479, if you're interested.
