thanks Wayne, the playground got small real quick flying 5" but i certainly do feel fortunate.
its definitely personal feel thing virtue. good thing is my son and i fly similar feel.. (have always shared toys) basically that last flight we had finally added the 10% TX expo after a couple weeks of pid/rate tuning only. i saved the tx expo till the last.
basically its just turning it on (put it in the loop) but it helps soften just enough at center stick to notice in the camera replay (not so jerky)
after the maiden flights, i stopped flying it and "Nate Dogg FPV" aka my 20yo did all the test flights. i asked for moves, constant feedback and watched vids to make changes. (lots of looking up)
yesterday, adding TX expo was my first time flying after betaflight tuning.
i only have one set of gear and trading back n forth is hard on goggles and increases chance of TX mistakes.
plus i wanted to see if i could tune it withought flying... just for fun.. make it a team thing. it worked.
