We need a new power core for the next drone. I’m thinking of a retro‑style, single‑cylinder unit, but with a torque curve that keeps the bot moving quietly in a stealth zone. Your late‑night tweaks could give it the edge we need—though I’ll keep the data on paper, not in a flashing HUD. What’s your take on rev‑level tuning for silent, lethal performance?

Sure thing. If you want that stealth vibe, keep the cam flat and low lift, run the port a little tight so it only coughs out power when it has to. Drop the idle to a few thousand rpm, and use a low‑rev, high‑torque cam—like a flat‑head with a big lobe that still spins. Then you get that whisper of a roar, not a scream. Keep the ignition slightly advanced at low load, retune the fuel for a leaner mix to reduce heat. That should keep the bot silent but deadly.

Good. Keep the idle at 2000 rpm, monitor the torque curve closely, and log every tweak. I’ll note the cam lobe profile on paper and make sure the fuel map stays lean enough to avoid excess heat. That’s the only way to keep it silent but lethal.
