Hi Peter, We have 2 piece ULF one built and fly around for 10 years. I have 278 flights to today. My brother has about the same number. We have 6 ready to fly ULF one in our club. Here is a picture of our self built Member 60 saw. A CNC milling machine I have. I have not used for construction. Best regards Josef -----Ursprüngliche Nachricht----- From: Member 100 Sent: Saturday, September 27, 2014 7:22 PM To: [email] Subject: Re: [ULF-1] Ulf-1 Digest, Vol 57, Issue 4 Member 67, Pictures would be great. I don't have a CNC machine but there may be some local firms that I could sub it out to. What did you use for cutting the Member 60 pieces? Is your ULF completed and flying?
