Not just electric motors but cheap, high quality flight controllers. That and kickass batteries.

The nitro helis are no slouches either, they're all capable of insane 3D maneuvers in the right hands.

The exhaust plume of a nitro doing the same things is kind of more interesting IMHO, it's like a telltale in a wind tunnel test. I'm surprised they don't put a smoke bomb on the electrics during these demos.

I don’t think so, engines on RC aircraft are quite powerful compared to their weight which isn’t a case with “real” aircraft. There’s a number of issues that can happen (and probably kill the crew) but it’s the most fundamental issue.

Only event I know of is this: https://www.reddit.com/r/nextfuckinglevel/comments/jmtvch/tu...

I think that's a few too many Gs for human pilots.
