[Fast zoom on real Lycoming engine photo + dramatic music]
“Car engines stand tall… but every small airplane you’ve ever flown has a FLAT engine. Why? Today we’re tearing apart the horizontally opposed reciprocating engine – the boxer that powers 90% of GA aircraft. Theory, construction, every major part – FAA style. Stick around till the end for the opposed-piston mind-blower nobody talks about.”
0:45 – 2:30 Why Opposed? (The Big Why)

Perfect primary balance (left & right pistons cancel each other)
Low profile → fits under cowling
Prop pulls straight through centerline
Super smooth – no annoying vibration in the cockpit

2:30 – 6:30 The 4-Stroke Cycle in Opposed Engines

Intake
Compression
Power
Exhaust
“In opposed engines the pistons on opposite sides move together but fire 180° apart. That’s why they’re buttery smooth compared to inline car engines.”

6:30 – 11:00 Full Construction Breakdown
Crankcase – Split in half, magnesium or aluminum
Crankshaft – One-piece forged, counterweights, dynamic dampers
Connecting rods – Plain type (no fork-and-blade like radials)
Cylinders – Steel barrel, aluminum head, deep fins for air cooling
Pistons & Rings – 3 rings, oil scraper critical
Valve Train – Hydraulic lifters, sodium-filled exhaust valves

11:00 – 13:00 Firing Orders & Balancing
Most common: 1-3-2-4 (4-cyl) or 1-6-3-2-5-4 (6-cyl)
Counterweights + viscous dampers = no destructive vibration
13:00 – 14:30 Opposed-Piston Bonus (Viral Hook)
