I think the record alt is a lot higher.

I can't verify it, however wouldn't the Air-Force's UAVs fly higher than that?

Sure can...and a price a bit higher...

I have seen video of a guy that took a RC helicopter to FL99 but the record is stated as 6022 feet. The RC airplane record is currently FL270 (26990 precisely) but there is a project in the UK to fly to FL300 or above. UAVs dont qualify because they have an autopilot feature.

That's probably one of the dumbest things I've seen done with an RC airplane.  Fly an incredibly small target that you very likely couldn't see anyway in clouds in the way of airplanes with people on board.

Bad damn idea.

The video Skyguns posted is of a pilot flying from the ground. The records are usually set by the pilot riding in an airplane and climbing with the RC plane or helicopter.

As you can see, there is a TV camera on board.  Most likely, they are flying using the monitor as vid source and not the naked eye.

Hams do this quite a bit with ATV on 432 mHz as the video source, but do not fly near airports or much above 2,000'.

At 6,000' anywhere near where light aircraft are is not a good idea....just for safety's sake.

I don't believe it is relevant weather they were using a TV camera or the naked eye.  ATC owns that airspace and would no doubt frown on hard mechanical nuggets in their clouds that they were not aware of.  Golfer is right, its a dumb thing to do...but it is kinda cool.

I would assume these RC-pilots did the same thing as rocketeers. Call the FAA and tell them where they're launching and how high and far the rockets are expected to travel.

The only think that suprised me about that film was that they were using a PCM raido. PCM radios are a typical FM radio, and is far more limited to range than the new Spread Spektrum technology. Spektrum is supposed to go as far as the eye can see plus. I never knew that PCM can go that high.
I know this because I have 2 Spektrums and use them for all of my airplanes. I used to have a typical PCM reciver and they would crash alot becasue of range problems.

At work during actual missions we routinely fly the RQ-4A "above" 50,000 ft.  I could tell you just how high but then I would have to kill you.  Fear the mighty Global hawk.

Agreed, my thoughts exactly.

No FOD!

Bosco I have been flying RC for a lot longer then your lifetime and I never crashed due to range issues even back in the AM radio days. My first radio was a 'pulse' kit that never need crash but the second 'store bought' unit suffered from metal-metal vibration inside the receiver itself (not well thought out) and ended up making a twenty-three mile unscheduled thermal flight. It was discovered in a cleared cotton field and returned to me undamaged. So I have to ask you why you fly beyond visual range?  :D

Most of the time when we had range issues it was because that reciver was in a previous crash. I watched a guy go as far as he could see with a spektrum, needed my eyesight to bring it back, and stil did not lose range.
I have been flying for 6, but I started around 12 years ago.

 I, Like challenge have been flying r/c for many years ( 34 to be exact  ;) ) I have never lost a plane
due to range issues with PCM gear. If you have ever been to a sailplane contest, you know that those pilots
fly quite high. Range has always been out of sight with the exception of some of the recent park flyer equipment.

 I would strongly suggest that after a crash, you have your receiver(s) sent it in to be sure they are OK.
Why would anyone take the risk of flying a model with suspect equipment. Personal Injuries can occur, nevermind the loss of the model.

Chances of hitting another plane are so slim as to be nearly impossible. But then again when other people's lives are the risk, thats not something to mess around with.

Waldo,
Don't need to worry about that now, Spread Specktrum is the greatest, until somthing else comes out that is better.
