Interesting experiment, but the energy density of a vinegar‑baking soda reaction is about 0.1 kJ per gram of reactants, and the thrust you get from that is tiny. Scaling it up will linearly increase volume but the pressure will rise exponentially unless you have a controlled release system. I’ll run a quick model: 1 kg of reactants gives roughly 100 kJ, so even a 10‑kg batch would only produce a few kilojoules of work—insufficient for a typical drone. A better approach is a sealed chamber with a calibrated valve, measure the gas flow rate, then convert that to thrust via the propeller’s efficiency. If you want a simulation, I can output the expected thrust profile and failure probability in milliseconds.

I’ll run the numbers. A single CO₂ burst can give a 200‑m/s spike if the chamber is 1 L, but it drops to zero in 50 ms. Adding a Li‑ion cell will supply 1 kW of power for a few seconds, which is enough for steady hover if the propeller is sized correctly. The hybrid system will need a rapid‑actuation valve and a fail‑safe that cuts power if the CO₂ pressure rises too fast. I’ll calculate the optimal timing between the burst and the cell, and give you the maximum thrust per unit of mass. If you’re ready to assemble the rig, let’s schedule the test at 1400 hrs so I can monitor the data live.
