1/5th scaled MIG-29 fighter-jet pre-flight, flight

I was thinking the same thing when it was making those high-speed passes above the "runway." 😀

But here's one thing I've always wondered. Is it possible to make a 1/5 scale or larger FLYABLE version of the F-16? From everything I've read on the F-16, it was designed from the outset to be completely unbalanced and basically unflyable, b/c its natural tendency would then be able to change direction at a much faster rate. It's what leads to the machine's highly maneuverable nature.

The only one to combat this (AFAIK) is with its fly-by-wire control system which is constantly altering control surfaces to ensure that the plane is flying level when you want it to, and pulling 9 Gs if need be.

So how would it be possible to produce a working scale model of an F-16 that could be controlled by a single operator?
 
NFS4 - you would need a computer on board, similar to one in real plane. Program it in ASM to keep plane level.

In the vid, turbines aren't put to full throttle. FAIL.

Bah. Screw stabilization. It need to be maneuverable enough to hunt seagulls 😀
 
I suppose these uber powerful jets can lift several pounds of rockets...or at least pneumatic guns (like air rifle) with auto load...

Perhaps I'm not understanding what they mean by 1/5th scale....because it seems too small to be that.

I was thinking the same thing, but hey whatever 😀

the fly-by-wire is automatic and is not handled by the pilot at all. The pilot just steers the f-16 and the plane will do what it can to not flip out because its center of mass is not in the front. I suspect a remote controlled version would be like that as well.
 
That was insanely cool. Needs a camera in the nose to relay the view back to the ground, though.

Well, I know that the FBW is completely automatic without pilot intervention, but how much processing power would you need to keep a plane level if it were an exact scale replica?

All of the scale (flyable) models of the F-16 that I have seen have vastly larger wings and control surfaces, vertical stabilizers, etc to fly properly.
 
that has to be 1/50th scale, not 1/5
but damn, those are some big engines in a small plane!
that's some nice r/c piloting, too.

Not much at all. I have pretty extensive experience designing autonomous systems and it could easily be handled by a 10mhz microcontroller running a fuzzy logic routine. It's a pretty simple concept. You fit the plane with sensors for whatever you are trying to stabilize. Read the values in and do whats called defuzzification of the output which is based on rules setup by the designer. I did this exact thing for an autonomous robot which had to avoid any object in its path, and by reading ultrasonic sensors it would determine the best path to go and how to power the motors to get there.
