Like every machine flyboard or jetpack will last for long if you will take care of it. As we do flyboarding since 2012 we know how to care about it. We strongly recommend to exchange all bearings ball include board and the hose swivel (122 +39), the foam sealing ring, nozzle sealing PTFE Ring, nozzle sealing O’ring every 50 flying hours or every 2 years. After that period the bearing balls are weared out or even changed their shape. You can notice it. The bearing is not working smoothly. In extreme situation their can be even broken which is super dangerous. If you change them we also recommend to change the foam sealing ring and the plastic gasket too.
