I am just building a screamin deamon, I found here on RCU.
And I had a hard time finding any delta. To the costs - this one does not come with any hardware, no pushrods, hinges, screws.
Basically just some balsa sheets and profiles and the laser cut ribs. Most deltas are designed very simple, so I don't know
why they all disappear. Delta kits shouldn't be that expensive.
Maybe the chinese read this and put an ARF together for 50 bucks - I'd take one
