Completely OT - Fokker!!

Botch

No, not @Focker.  
It's been 35 years since I got out of this hobby.  Wow.  The models have gotten bigger, and this guy's skills are killer.

I had an old Heathkit radio that was broken more than it worked, and was never very good at flying these things.  I got really good a building them (and, RE-building them) and my masterpiece was a Stearman PT-17 (only a 4' wingspan on mine, though).  
Anyone else dabble in this?  I know @nolaegghead just got a drone, it looks like it flies itself (and I'd love to have one follow me on a ski run!).

That is pretty awesome!

WOWSER!!! I wonder how much money he has invested in that hobby - I bet it is much-o !!!

Awesome.  Snoopy would be impressed!

As was oft said during the war, "Send them Fokkers in their Messerschmitts straight to Hell!!"

I’d hate to imagine crashing something like that, on several levels.

I flew for about 20 years, every weekend Sat & Sun.  I competed in Quickee racing, Scale Warbird Racing Association, and a few IMAC events.

My race plane was a .40 size T-34, with a supercharged YS .91, with worked intake and exhaust.  Prop was so big my spotter had to hold it on the rear wheels and lift the nose.  Front wheel never touched.  Had compression adjusted so it stopped with prop horizontal (hopefully) for landing.  Deadstick every landing.  Ran 85% nitro and 15% oil   .... clocked it at 180mph.  Lots of carbon fiber to keep the wings and stabilizers from snapping during full G turns.

Bad picture, but all I have:

Not me, but same idea.

Awesome...i couldn't fly the ones on a string spinning in circles...pulled the motor and built an air boat...parents loved the film it made in the pool

@Ozzie, I can already tell you I've never had the reflexes to do something like that!  Those things are flying!

Very cool man!

Rather than start another thread, had to post this "other end of the spectrum": an 8-channel P-51 Mustang, that the builder had to design a 3D stability unit to be able to fly it (its extremely fast).  See how big it is!!

The next video that shows on EweTube shows it in flight, quite amazing!  
I was an Aero Engineering student my first couple years of college.  There's a quality called the Reynold's Number that doesn't scale up or down like area, velocity, lift, drag, etc.  Leaving out the math, basically the larger a wing is, the slower and easier it can fly; this is true for airplanes as well as birds (watch how frenetic a sparrow flies as compared to an egret).  Note how fast this Mustang has to fly compared to the Dr-1 in the first video; fascinating!

Scale speed of Mach 3!! That is insane.

Here's the piloted end of the spectrum. These things are the hot-rods of the great plains
