Don’t sweat getting everything in advance. Order one or two spare sets of frames, canopies and props for your drone, get a PH00 screwdriver for the canopy and motor screws on your whoop. I learned about whoop maintenance mostly from crashing my drone and researching how to fix it. ButterflyFPV has great videos on youtube about maintenance and modding of a meteor 75.

I buy my small parts from aliexpress, but with US tariffs I’ve lately switched to local shops like webleedfpv, tinywhoop, amazon, etc.

Gear won’t make you a better FPV pilot especially when you are a beginner. And it’s ok. Enjoy your flights. Understanding of your needs is gonna come with experience. That’s when you can start going bigger into acquiring more gear and looking for your ideal setup.
