Speed of turbine RC aircraft is not a problem.  How about 727 Km/hr

The 9N is the idle thrust, full power on the P220RXi engine is 220N ;)

I have been building and flying turbine models for the last 10 years, and believe me, this is not something you learn over a weekend ;)
Flying these things with the speeds they go at, takes a long time to master. And mine are "slow movers" in that world doing only 350 km/h or so.

OT: There are so many reasons why this is nuts, go hire a fullsize pilot and plane and go play with that. Or find another hobby....

In my Country the max speed is very low:

In Italy the Train goes often faster:  :-[

How does it handle when something happened outside of there parameter? That way I want use 3x Units who must confirm the other 2x or the Data get thrown away to reduce the chance for an error.

--- Quote ---building a RC plane that can fly at 250kph is doable but very hard.

So what is major problem with? Frame, Structure, Wings,...? The good thing with an Autopilot System the can react much fast and can overwatch all parameter at the same time. That mean for example if one of two Engines Vibrate to much, get to hot,... the can immediately abort the flight and land on an designate alternative landing strip (aka Grass) where someone from a Recovery Team wait if there is an emergency landing. An Model who is fly by Hand have much more trouble to over watch all parameter and decide to land before something happening.
Here is a Video where an derailing happened in Vienna.

Swatch how long it take until the Train stop. I am not sure but I think there is no safety gear who check if the Boggy is on the Track or not.  ::)...
If there where any the Train would immediately make an emergency break.

Big Aircraft = room for Fuel
Thats another thing to calculate.

In Germany a Guy build an huge A380 Model:

sure the will be lighter but that is the Wing Size I would stick with.
The Wings could made out of a Fiber Material. Maybe Glasfiber or Carbon (depend what the Backing Cost).

Thats not work I need a Dom Camera who is controlled by Software for follow. The must also shock and rubbel profe.

Autopilots with millions to billions of dollars invested in their development still fly planes full of people into the ground. Sticking a pi in an R/C plane is not a magic solution to making it handle anything.

Also that A-380 model probably cost at least 6 figures. Those turbines are a few thousand each. When you crash it because you have no R/C experience you will wish you had hired a real plane.
