Full-size 727 controlled by Futaba 8FG!
The Discovery Channel recently decided to crash a radio-controlled 727 to gather valuable scientific data. To fly the monster aircraft, the team they contracted with selected the Futaba 8FG.
Watch this epic event unfold this Sunday, October 7, on the Discovery Channel at 9:00 p.m. Eastern Time (8:00 Central). Check your local listings for details. Until then, you can read more about the team that pulled off this amazing flight at the link below — see pages 8 & 9. http://www.nxtbook.com/nxtbooks/mcmu...tid=Cover3#/10 http://dsc.discovery.com/show-news/o...n-history.html |

If they only wanted to crash it they should have used a Spektrum radio .

RE: Full-size 727 controlled by Futaba 8FG!
I have seen this on either the History Channel or Discovery. The 2 hour show is suppose to air this Sunday I believe 9:00p.m. eastern time. I am not 100% on the time.

They would have been derelict to use an R/C system to control that aircraft. I suspect they just used the transmitter as a control device and used a fully redundant high power transmission system.

We could get reliable transmission to the moon with 2W but we had a transmitter antenna gain of 54 db and our receiver had a cryogenically cooled MASER( like a LASER but used RF instead of light) preamplifer |
RE: Full-size 727 controlled by Futaba 8FG!
I dont how they did it but suspect that after the pilot bailed out the plane was on auto pilot untill it came into range of the 8FG. I also suspect
they did not use a stock receiver either. |
RE: Full-size 727 controlled by Futaba 8FG!
I would like to know how the pilot bailed out. After D B Cooper bailed out the rear door they made impossible to open that door in flight. We don't even know if cooper survived the jump. Its hard to walk down a stair in a 200mph wind.

RE: Full-size 727 controlled by Futaba 8FG!
You should go read the articles. The reason they chose this type of aircraft is BECAUSE of the exit.

RE: Full-size 727 controlled by Futaba 8FG!
The pic I saw he bailed out the rear of the plane in fact it looked as if the door had been removed. In any case i'm sure whatever they did to prevent in flight
door opening could easily be overcome by aircraft mechanics. |

Spektrum are JUNK. my friend has lost $18,000.00 in planes this summer. The other day I lost a $500.00 plane.

RE: Full-size 727 controlled by Futaba 8FG!
A simple tab device that turned into the windstream was the lockout on the rear door-easily removed if needed.

Dang-you have stupid friend-why would your friend continue to use it and more importantly why would you still use one if this was true-are you stupid too?

We don't even know if cooper survived the jump. Its hard to walk down a stair in a 200mph wind. It would be impossible to go out the side. The stabilizer would make chopped meat out of you. You would have to go out that under the tail door. Even so you wouldn't get far down those stairs in that wind. I really doubt you could get out without hitting something. You would have to take those stairs and the door completely off and have an open space to jump into. Even so that 200 mile wind will be a sever shock when you hit it. I doubt many would survive. Paratroupers jump out the back of their airplane but they are well conditioned individuals. You see them jumping out the side but the airplane has dropped down to a very slow speed. You can't slow that 727 to much below 200mph |
RE: Full-size 727 controlled by Futaba 8FG!
Check the landing speeds, a loaded 727 has approach speed of about 130 knots.

You can't slow that 727 to much below 200mph Yes you can slow a 727 considerably below 200 mph. You do not have to have the landing gear extended to have the flaps down for lower speeds at various flap extensions. Below flaps-25 you get a horn blowing if the gear is not down, but a circuit breaker can silence that. The rear stairs can be used as an escape door. The horizontal stabilizer is very high on the vertical stab and would not be a problem. OTOH, engines 1 & 3 just may well be such for a side jump!!![&o] Approach and landing speeds were a function of weight at any given time. BTW, I had a couple years in the USAF C-123, a fun machine, and deployed paratroopers many times, all out the back. |
RE: Full-size 727 controlled by Futaba 8FG!
It must be a modified Futaba 8FG to increase transmission power. To take off and crash the 727, you certainly need more than 1-2 mile of controlling distance that a normal RC air radio is capable of reaching.

However, when I participated in flight test for Boeing as a flight test engineer, it was not considered safe to get below 200mph. If you found otherwise, I am glad to say I was not aboard when you tried it out. Its not the first time a pilot has done things considered questionable. Remember Tex Johnson rolling the 707 prototype? He almost caused the CEO of Boeing to have a heart attack. |

They considered Spektrum but later decided it was a waste to crash a perfectly working system, someone else could use it again.<div>On the other hand Futaba is ok to crash and trash.:D</div>

That same handbook calls out a stall speed of 163 KIAS for a -200 weighing 170,000 lbs with flaps up. That stall speed decreases as flaps are extended. At 170,000 lbs with flaps at 25, stall speed is 111 KIAS. Pretty slow. |
RE: Full-size 727 controlled by Futaba 8FG!
If one took the time to find out just how many people have actually have used the 727 rear stairs to jump, they wouldn't look foolish telling a 727 captain what the plane was capable of:eek:
Three more copycat skyjackings followed the D.B. Cooper affair in 1972 alone, all three perps were later captured, all survived the jump. At the World Free-fall Convention in August 2000. 180 skydivers paid 59 bucks each to skydive off the rear stairs of a 727 from 14,000' at 155 knots. I would have to assume the crew was on oxygen and the plane wasn't pressurized in this case. Pete |
RE: Full-size 727 controlled by Futaba 8FG!
OK I give up.
But you had better stay off that rudder at that speed. We had a case where a pilot from some airline put in to much rudder on approach and it snapped. It was a 720 I think. It was 50 years ago. My supervisor on AWACS was one of the survivors. |

If you friend has lost $18,000 in planes in onesummer..then he is really doing something wrong...... how many planes is that? If I lost just two planes to the same TXI would bin it and replace it with another.. Electronics can certainly fail, this can happen with any brand... My experience with all the latest 2.4Ghz radios (including JR also) has been 100% Perfect across over 30 planes, helis, and small BNF eflite helis... |

My experience with all the latest 2.4Ghz radios (including JR also) has been 100% Perfect across over 30 planes, helis, and small BNF eflite helis... I have attended many RC model meets, but the one that had the most expensive RC models was the Superman Jet Meet. I attended that meet for the last 13 years that it was held. Some of the finest pilots and most expensive jets were flown there. At one event, Wolfgang Klure brought his immaculate scale Mig 29, which he had flown and won at two Jet Scale Masters events. He sold it to a collector for $29,000. A friend of mine and an excellent jet pilot had a Futaba 12FG radio with hundreds of successful flights on it during the first year he owned it. One day, he lost two jets in an afternoon due to faulty transmitter pots. He had an estimated $15,000 tied up in each jet. He replaced that transmitter with a 12Z and has been flying with it for the past 4 years. My point is that Yes, RC models can cost $18,000 and you can have a radio fail from any manufacturer at any time. If you lose faith in one manufacturer's radio you move on to another model radio or another manufacturer's radio. |
RE: Full-size 727 controlled by Futaba 8FG!
I'll be the first to admit I'm no expert on radio propagation but I also can't see why it's difficult to think a handheld TX like ours would not fly that jet. Infeasible? Yes very. Impossible? Don't think so. What I base my statement on and taking into consideration I have not tried it with 2.4 is 72mhz. So with that I will ask. Has anyone ever took a 72 MHz TX with a 10 MW output and stepped out a distance with a field strength meter and did a measurement, than tapped a 15 DB gain Yaggi onto the TX and then remeasured? Yes it's infeasible but possible. Now I know we can't do that with our flying but we are still talki g about flying the 727. Right?

RE: Full-size 727 controlled by Futaba 8FG!
FWIW...when the pilots bailed out and the jet was being controlled by R/C, it was from a Cessna Skymaster flying formation with it.
One of my friends from work was the man who did it. Beave http://www.rcuniverse.com/forum/m_10...m.htm#10704602 |

What you do on spacecraft is make the spacecraft able to manage on its own then send programming instructions periodically. A 727 has only an autopilot. If your RC control failed it would fly off to who knows where. |
