Ran across some youtube videos at work while showing a buddy my diamond dust delta wing.

I know hobby king sells one. But from the rc model reviews, looks poorly built. But maybe have improved. Might be a long shot I know, but is there anything else available out there? Saw a vintage dynajet on ebay for sale.

Now I did run across some plans on ebay, but I do not have a lathe and mill out in the garage. Nor do I know what a local shop would charge to make the few parts I could not do on my own.

Thanks for any help.
