You're barking up the wrong tree. If all you need is some directional controls, I've got some Atari style joysticks here that would be 100% up to the job. Manufactured in the '80's, built like a tank, seen plenty of action, all still work fine. Want better / new, have a look at what people put into arcade cabinet rebuilds.
What makes these things so reliable is their simplicity: a bundle of wires + some switches (of well-proven, battle tested design). So failure modes come down to cables / connectors, and mechanical wear. All of which is trivial to troubleshoot. In a pinch you could pull a cable, strip some wires & you're back in business.
Now for a carbon fiber hull, that's a different ballgame. So there you want independent experts, who know the intricacies of the materials used. Non-destructive testing using methods backed by actual science. Maybe destructive testing to find out where breaking strenghts actually are. That's where certification & 3rd party review come in.
But it's not the "certified" that makes something reliable. It's knowing a design through & through, its properties, strenghts, weaknesses, limits, failure modes & how to address them.
Grabbing an off-the-shelf game controller to steer the craft: defendable design choice. Skipping 3rd party certification (or even review) of something as critical as a pressure vessel (built using innovative tech): not so much. Never mind using a viewport that was rated just over 1/3 (1500m) of what it was used for (3500...4000m). That's just insane.
