It's been a while now since we heard anything, last in April. Jeff expected production to start in June. Another month would easily be possible due to supplier delays so hopefully they're just in production now. If so, I expect another update shortly.
Just had another update on the ShareRoller. Last minute production niggles are being sorted and some parts are awaiting delivery. Most parts are on hand. I don't have a good estimate on when they will start delivery. Could be another month, so September at the earliest.
So far Helix and ShareRoller are tracking each other in delays. Just my luck, picking 2 projects with 2y delay. But both seem to be imminent, no sign of moribundity from either.
