RE: Diamond Dust RC?
Screw-In
The Diamond Dust are no more. I believe Jeff Gilbert Sr. passed away, and his son Jeff Gilbert Jr. was having the DD sold through a company called Tetrecam Inc. as I understand it. Trectracam was the last co. that I am aware of selling the kits and I guess they sold out. Tetrecam is no longer offering the model for sale, and Diamond Dust RC is not responsive at all. Couldn't even send them an email.
The Diamond Dust is not hard to build. The Manual is still online at the Diamond Dust RC webpage. I have a plans set I would be happy to send you (Send me a PM).
