Default Breaking the sound barrier - possible?

Just a silly Friday question, but here goes...

Is there anything keeping an RC aircraft from traveling at Mach 1?

Okay, it would be very difficult to keep an eye on, let alone control, but since practically anyone with a couple of dollars can get a Funjet to do 150mph+ (with quite a few claiming 200mph+), surely an old pro with sufficiently deep pockets could get a plane to go a whole lot faster?

200 mph is a long way from 768 mph (at standard conditions). It certainly isn't possible with an electric ducted fan.

I have calculated at 200 MPH you have 6 seconds from one side of the sky to the other on turbine jets before you have to turn.

The fastest RC jet went 340 MPH. The fastest recorded RC airplane was a glider, there is video of it on the net. Over 400 MPH. Using a standard remote.

I would say breaking mach would not be possible with our means (IE a standard remote control) . However, governement's break the speed of sound by remote control all the time. And have been doing it for many many years.

So yes it can be done, just not on your budget or mine
