RE: Can an RC pilot plateau? Only if you don't try something new.
It is hard to lose the FS mindset when flying, "bent metal is bad".
But in order to progress you have to push yourself beyond what is normal for you.
Get up higher to give yourself some time to recover, and then try something new.
I have heard, and seen this regarding getting better at flying.
"Fly it like you stole it"
Or on the flip side....
Do not get to attached to your airplane.
Worst case, you waste some balsa.
Lord knows I wasted balsa, foam, carbonfiber, fiberglass, batteries, RX's and Servos.
