FAQ

What maintenance does the JM50 require?

Regular maintenance includes:

  • Visual inspection before each use
  • Cleaning of the fuel filter every 10 operating hours
  • Inspection of all fuel lines and connections monthly
  • Lubrication of bearings according to the schedule in the user manual
  • Annual inspection of the turbine blades and combustion chamber

Is JM50 suitable for classroom demonstrations?

JM50 was designed with educational settings in mind. It can be built indoor but we don't recommend soldering or operating it in a classroom setting.

Operating a jet engine requires:

  • Adequate ventilation
  • Proper safety barriers
  • Hearing protection for observers
  • Adherence to safety protocols
  • Adult supervision and proper training for the operator

Please refer to the safety notice for more safety recommendations

Can children operate the JM50?

No. JM50 is not a toy and should only be operated by adults with proper training and understanding of the safety protocols. Children may observe demonstrations or control RC vehicles under close adult supervision while maintaining a safe distance from the unit.

What's the main difference between JM50 and KP35?

KP35 was designed to learn core jet engine principles.

JM50 offers more thrust and can be integrated in RC vehicles, letting you learn engine building + RC vehicle building.

Do I have to be subscribed to the community to access learning resources ?

Yes. Learning resources are available exclusively through the community. You get 1 month free subscription with the purchase of your engine
