The latest update posted tonight promises the test bikes will be finished in the next two weeks, just like all updates posted since September.
I think they are having serious welding problems or their the 5-axis CNC subcontractor is unable to do their job. Either way, things don't look good.
They have gone from an initial plan of building the frame using 6 jigs to the current estimate of 10 jigs. I would guess that the cost of welding the frame is now 50 to 100 percent higher than initially expected, and they still can't make a test frame after 3 months of trying.
Helix's probability of success continues to drop.
