- Engines need to be sonically tuned for maximum efficiency.
- Noise is very similar to a pulse jet engine, which could cause of discomfort for passengers and people on the ground.
- Very high engine temperatures are a problem (the engine can glow bright orange which creates an obvious material problem).
- Difficult to mount due to operating temperatures, intake valve assembly and fuel supply.
