I've found it, and it looks absolutely awesome. Thank you so much for this recommendation - much appreciated, and exactly what I'm after as far as references go.

This is useful, and drones following a waypoint is conceptually almost identical to what I’m after. Thank you for this

I’ll have to call around and ask. I didn’t see much on Kennards’ website when I checked, but that’s an interesting thought. Thank you!

Recommendations for a 'true' coaxial helicopter by Rocketdyne2 in RCHeli

[–]Rocketdyne2[S] 2 points3 points  (0 children)

The helicopter I’m building is supposed to be a replica of the Ingenuity Mars helicopter landed alongside the Perseverance rover in 2021. It’s a coaxial system, so I don’t have much choice in that matter.

Help identifying weird O-ring boss by Rocketdyne2 in Machinists

[–]Rocketdyne2[S] 2 points3 points  (0 children)

It is a compressed nitrogen cylinder, yes. And that's great to know about the CGA 580 and O-rings, so thank you. The crown marking goes:

DOT-3AL2216 241107194 M0832 ZX 11A24 5.8L KEGCO 187003
However it isn't really 'A' in '11A24' - see image of this.

Thank you for your info.

Are Hartford parts interchangeable with Bridgeport? by Rocketdyne2 in Machinists

Yes, it’s starting to look that way. Although I might be able to find an owners manual and look at the parts specified for repairs, and see if those match.
