Drive Belt – Check the Poly-V drive belt for cracks or wear. Ground Running - Bailey Aviation recommend that you DO NOT ‘Ground run’ the engine. Experience has proven that the ONLY safe place to run a paramotor engine is with it firmly strapped on your back. All pre-flight power checks are best performed whilst wearing the paramotor on your back.
