Im at about 8 hrs on the engine and 4 hours flight time. I know I need to check the fuel filters soon and likely do a first oil change/check the filter and magnetic plug. At what hr are people doing these checks? Also it seems a 25 hr Rotax warrantee inspection is required. Should I wait and do all the above then? What are others doing? What all am I missing?

Of course Ive been inspecting the airframe and engine thoroughly after every flight but I want to make sure Im not missing something.

Thanks!
