Hey all,
Making a few placeholders for sharing a project I've been working on: a really large ELEV-8. Daniel has been at my home office for a couple of days and we've stayed up late to build this buzzard. We just finished the maiden flight and have so much to share, so it'll have to unroll over the next few days. Some specifications:
Video, details and drawings to follow. I could probably be talked into making the parts for anybody (this was so much fun!). I'm happy to share every single piece of the project.
I realize a couple of customers are looking for me and I haven't responded. A massive amount of e-mail communication piled up over the last couple of days while I've been messing around. and I'll get back to you as soon as possible.
For now, the placeholders.
Sincerely,
Ken Gracey

- Will carry lunch for five, a dozen Boe-Bots, etc.

I like the "lunch for five" feature but that's just me!
And you're one of the guys to whom I owe a follow-up, so thanks for your patience Rick!
I would like one a bit bigger capable of lifting 70 kgs ~150lbs
Waiting for the day to fly in one!
Any video to post?
What is the status?
Any thought of adding additional GPS hardware/software to enable flight according to a predetermined flight plan?
Very impressive!
Just keep Matt G. at least 60 miles away when you fly it again.
Looks like it's working great!
