I think a lot of people here are vastly overestimating what is required to build an RC plane that would outrun a typical helicopter. Most ARF (almost-ready-to-fly - just add your radio and a batter pack) electric-ducted-fan model planes in the $400-$600 range would be able to hit 150-200km/h (see https://www.motionrc.com/collections/rc-jets/products/freewi...). When you jump up to turbine power, it’s a little more expensive, but you should be able to get quite a bit faster. Head over to YouTube and you’ll see plenty of RC planes breaking the sound barrier.

Add a FPV system with a low lux camera (see https://oscarliang.com/flying-fpv-at-night/) and you could fly this around at 10:30 at night (although there are not too many sane RC pilots who would wish to do such a thing.)

This “advanced drone” could be built with entirely off the shelf components for a few grand.
