Dogfighting with RC planes would be on another level of twitchiness compared to sim flying - smaller/lighter, much more susceptible to gusts of wind. Not to mention the inevitable crashes - I'd rather spend my money on a PC where if I do crash then I just restart as and where I want - not a few weeks in a workshop fixing the plane
Don't get me wrong, I love RC planes, and flew some for a couple of years - inexpensive RC planes do exist, but as with everything, you'll get better results the more you pay.
Damnit.
You might've just woken up an itch in me that's been waiting to be scratched for the last 15 years or so...
Oh, and latency free RC over long distance - not gonna happen.
