Engine break-in tests

Sky Power handles break-in tests for your engines. The engines are broken in on the in-house engine test stands according to your specifications. So you obtain a “ready-to-fly” engine that can be used immediately in your UAS. That way you can save preparation time and begin your deployment immediately. You can generate instant sales with an engine broken in by Sky Power, especially in industrial and commercial applications.

Customer and endurance test (engine tests)

Sky Power conducts engine tests according to your specifications. Individual usage parameters can be simulated in the process. Each engine test is documented. Of course we make these results available to you. Thanks to highly exact measuring instruments, fuel consumption, engine parameters, and exhaust-gas temperatures can be measured. The engine tests can also encompass endurance tests during which your engines are subjected to between 50 and 200 hours of uninterrupted loading on the in-house engine test stands. Climate tests are also possible. After each test, the engines are disassembled and examined.

We can conduct the following tests for you in this context:

  • General performance measurement of combustion engines
  • Thrust and power measurement
  • Exhaust analysis
  • Engine indexing
  • Endurance testing
  • Blower-, water-, and oil-pump analysis
  • Cylinder-head measurement
  • Load-change calculation
  • EMC measurements
  • Climate and temperature tests

Overhaul and maintenance

The time between overhauling (TBO) of Sky Power engines can vary depending upon operating environment and maintenance intensity. After achieving maximum TBO, Sky Power can then overhaul the engine. The engine has to be sent to Germany for this.

The same applies for maintaining the engines. For each engine, there’s an operating manual, which describes the individual maintenance steps and their intervals in detail. This operating manual is sent along with the engines. Moreover, we recommend that you order the associated spare-parts packet for each engine. You can thus conduct simple maintenance tasks yourself at any time.

For larger maintenance tasks, the service can also be rendered at Sky Power in Germany. Please contact our Service department for this.


Only Sky Power’s Service can generally repair an engine after a crash. Before you send in the engine, please contact the department in order to clarify in advance whether or not a repair is even possible. Detailed engine tests are of course carried out as part of the repair work in order to document the engine’s operational readiness.
