If it's stable, you don't need a ton of experience to land, just get slower and slower really close to the ground (preferences being tall [needing mowing] grass) I belly land. Less stuff tomorrow to repair
If its stable, flying fast is easey with teensie stick movements. Big movements cause rapid disassembly.
EVERYONE is a newbie, first flight/new design. Experience means when it does something stupid, you think: the last one I had that did this, I corrected this way.
Carry on, I have popcorn and beer.
