things that might be helpful.
- prop direction: the letters/numbers on props also indicate what direction they are meant to go in. letter/number side is forward. no matter where your prop is, front, mid, back - the prop needs to go in the correct forward direction. Also, the motor needs to spin in the correct direction as well.
- CG is super important. "A tail heavy plane flies once, a nose heavy plane will fly again." its not that big of a deal with quads since everything is packed in, and out weighed by the battery, but for planes, it makes a big difference. check the manual/instructions for where the CG is, some planes will have a marker under the wing. keep checking it while your placing your components and figuring out battery placement. i tend to go a tiny bit nose heavy.
- you should probably learn to fly line of sight before going FPV. just incase things go wrong you can still bring it back safe.
- check your CRAP.
- maybe hold off on buying a jet or crazy fast plane for your first plane. its probably a good idea to learn on something slow and with a bit of dihedral in the wing (passive stabilization). my first plane was a slow stick, that thing was fun.
