RC Aircraft...The big ones...

Those are neat, but this is the biggest RC aircraft in the world:

These are the remote controlled aircraft (UAV) that I especially like!

I bet that there are some Iranian general officers that don't especially like the Reaper. The are probably quaking in their boots to think that the Grand Poobah in Iran is contemplating triggering their demise by retaliation strikes on U.S. interests...

Reminds me of this movie where the crew of a downed plane are saved by a model airplane designer

Flying Wings
A little drag (usually via toe-in) on the wingtips/winglets will usually provide enough vert stab function not to need any computer gyro assist. I built a "combat(1)" wing from EPP that instead of wiglets, relied on flattening the leading edge of the wing just a smidge at the tips.

I would bet that the B2 in the image did have some sort of computer/gyro assist. For something that large and expensive, dropping a cheap gyro on it is a no-brainer.

Cost of Toys
After I got into the hobby I could really economize. I used fan fold foam and re-used electronics (batts, xmitter, motors, etc.). I probably had a good $10 in non-reusable materials in most of my later builds. And $20 in electronics ($100 of electronics divided out over 5 builds).

I stayed electric the whole time and my vehicle could manage a 40" wingspan, limiting size. I am no longer in that hobby due to time.






(1) The object being deliberately ramming another plane to knock it out of the sky.
 
Out near LaGuardia and Speed's, near Flushing Bay/Northern Blvd, we flew planes on strings in the mid '50s thru early '60s.
Great skills to dogfight, cutting off the paper trailers, and land the planes in one piece

My Dad's buddies also helped pioneer RCs with lotsa radio gear in their vehicles.
They were all nicknamed "Radio"
The big bomber had 4 engines and a four foot wing span.
Talk about loosing fingers!

As a kid, 10-15, they explained everything and I built my P51 to fly on a string.
Did a hammerhead into the asphalt after an uncontrolled loop.
Kaboom ..... and time stood still :eek: :eek:
Got the Fox engine running but never had time to build another.

Markham Park has an airfield and always fun to watch choppers fly upside down... great skills and super fast aircraft.
I keep my Trap gun in the Van. :rolleyes:

Years later I learned not to push a Piper 140 beyond its intended purpose.... or if you do, have a lot of air below. ;)
