Most of today's candidates were clickbait-heavy aviation compilations or hashtag-spam shorts. This one stands out as a genuine engineering project: a solo builder designing a fully 3D-printable, modular RC aircraft and open-sourcing the whole thing.

This installment focuses on the motor mount assembly — a deceptively tricky part of any RC plane. The motor mount has to transfer thrust loads into the airframe, absorb vibration, survive prop strikes, and stay light. Designing one in printed plastic (rather than the usual aluminum or plywood) means thinking carefully about layer orientation, stress concentrations around fastener holes, and how the mount interfaces with the firewall and nacelle.

Because the channel is documenting an ongoing build, you get to see the iteration — the prototype, the rationale for design choices, and how the part fits into the larger modular airframe philosophy. That's the kind of context you almost never get from polished maker content, and it makes this a useful watch for anyone interested in CAD, FDM design-for-manufacture, or amateur aircraft engineering.

At 79 subscribers, this is exactly the kind of small, technical channel worth surfacing before it gets bigger.
