Well what a crock I am not a Top Gun winner hehehe or an expert with what 110 posts? (all on this thread it seems) But I have not had any issues with Spektrum accept one AR6200 which turned out to be a knock off even that worked fine untill I had a couple of bangs then it browned out- lost signal further away than 30feet etc.
The orange products are ok for foamies but how can you trust those over Spektrum? especial in larger planes?
Lemon make a better product than orange (what is it with technogeeks and fruit anyway)
It seems Voltage or lack of quality power deliver is the real issue here. Try A123 Packs with 5 cells.

Really ? Where were you during Futaba's "Zero G. U .I D." debacle ????
You need to do a bit of reading before making such blanket assertions . Search both here and at RCG the words "Zero Guid" and then come back here and tell me how infallible Futaba radios are .
ALL companies occasionally get it wrong . There is no shame in a simple mistake . There IS shame , however , in knowing of a mistake and not correcting it . Futaba did an A+ job with their recall and my zero guid TX was replaced painlessly .
If there IS a provable problem with Spektrum RXs , well I hope they would do the same and replace any faulty equipment . The problem here in this thread is that without just outright putting the video out there for all to see , all the folks have to go on is the printed words of a man who has attacked just about everybody whose responded to this thread . It's kinda difficult to get folks to see eye to eye , when your punching them in the side of the head in the process !
Are Spektrum RXs flawed ? Who Knows ? Time will tell ......
Are you winning many "hearts and minds" ? Well , a quick read of all 13 pages of this mess would indicate , NOT !

I still believe most crashes are caused by setup and component use issues due to a lack of experience, I say this because I have witnessed just about all brands involved in a crash with the pilot yelling I don't have it, or I'm hit at one time or another, who knows for sure. I can only go by my own experiences and move forward from there, brand bashing and name calling has it's place I guess but it's not really my cup of tea so I will just leave it at that. What I can show you is video of my 40% 260 being flown on my DX-7 radio with 9 moderate torque servos (8611s), on board, 2 ea. Fromeco 2200 ma lions supplying power to 2 each AR 7000 receivers and without the use of a power expander. For the record, I have flown this airplane 100s of flights with this setup without any problems. http://www.icanflyrc.com/JRFlyin/JH_...008/Bob260.mp4/Bob260.jpg
Now when I am setting up the larger stuff with 14 + high torque servos like 8911s then I use a power expander with at least 2 ea 2500 ma lipos supplying power like in this picture of my 55% 260 below. Spend your money and take your pick, that 's all any of us can do.

Ok here's the deal.
I went through the entire thread. If your post is gone it means it contained what I deemed a personal attack, was way off topic, or was deemed to be bashing/ranting.
If your post was EDITED by me it means I removed quotes from a deleted post.
If we can continue the topic with technical information and reasoned discussion then by all means, please carry on.
Any further personal shots will be dealt with one on one and I'll be monitoring the thread a few times a day.

But 90% of the guys I fly with in 4 cubs I belong to in 3 states fly Spectrum.
I just had a boy who thought he crashed all the time because of Spectrum, he switched to Hitec and just crash this weekend the same way as he did in the past

Never Ever Had a Radio Problem Flying C/L ....
JMHO but any 2.4 Receiver will Brown Out if the Voltage (For any Reason) drops below the threshold. Weather caused by a LOW Battery or something drawing more current than the bus can handle. One of the main problems with the DSM2 Receivers was they were 2 channel Non Hopping Receivers. If they were any good Spectrum would not of gone to HOPPING. Then there is the need for Satellite receivers ... Some thing wrong when it takes multiple receivers to get a good signal ... JMHO and I ain't changing Just glad I never invested in Spectrum.

Hi Guys -
I need to chime in here to hopefully get some advice. I bought my first Spektrum setup - the new DX6 - and used it in a Dynam SMART model plane. In all my years I have never had such a wild uncontrollable ride with a model aircraft. I finally ended up crashing and totaling the plane on the 5th flight.
Before reading this forum string, I had attributed my failure to unpredictable wind currents coupled with warped tail surfaces and a stripped wing servo; those were the only causes I could figure. However, after replacing the wing servos, and making other corrections, I still encountered uncontrollable flights. Now I am more inclined to think that much of the unpredictable behavior of the model may have been more to do with these "brown out" conditions being described here. I mean during all of the flights the plane would be cruising along and then quite suddenly go into totally erratic mode with sudden climbs, dives, or vicious banks ALL of which could be indicative of a bad Tx / Rx link. I have flown other planes in heavy winds before and never had problems with the Futaba analog setups I used.
I am getting ready to install the radio into another plane I have but am petrified to do so after reading this post coupled with what I have experienced with the Dynam SMART.
If it's a random problem how do I test for this?

You need to provide more information.
What brand/model receiver are you using?
As mentioned above,do you have expo set up?
Did you perform a range test before flying?

No, no. I didn't say I came from Futaba: I merely stated that I was using Futaba equipment in my other plane. I actually prefer JR equipment. I fly a Prote'ge' with Futaba equipment, but also have Airtronics, and JR. The Spektrum DX6 is my first spread spectrum setup and I was only using all Spektrum equipment in the SMART plane at the time. As a matter-of-fact, I never mix the Tx with other brand Rx equipment. For all I know, what I experienced may not be a radio problem at all...this forum string just caught my interest. I have certainly experienced radio jitter before, which was always due to poor batteries, but I've never experienced anything like this.

Great questions, thanks!
The DX6 comes standard with the Spektrum AR610 Rx, which is what I purchased & used. (http://www.horizonhobby.com/product/...ceiver-spm6700)
Unfortunately, I have no idea what is meant by "expo" setup.
Yes, I always perform a range check.
I will say, though, that the servos in the SMART are sh*t and I replaced them all except the dedicated nose gear servo. The right wing servo stripped out after the 2nd flight. On the ground, I never experienced any radio issues at all.
In previous flying experience, I've only ever experienced radio jitter either from local interference or from poor batteries. Both of those issues were always easily resolved.

HOPE THAT'S ALL IT IS BUT IT SOUNDS LIKE A BROWN OUT. CONDITION
DO THIS 5 MINUTE TEST:
PUT AIRCRAFT ON STAND,
BATTERY: 99% CHARGE ON 5 CELL 6V ( ANY KIND OF BATTERY YOU ARE COMFORTABLE WITH)
TURN OFF ELECTRIC MOTOR WITH "THROTTLE CUT" IF ELECTRIC
EXPO ON ...DUAL RATES 100%
SPEKTRUM Rx
REBIND PER MANUAL & REMOVE BIND PLUG
MAKE SURE YOU HAVE A SOLID LIGHT ON THE Rx AND SATELLITE
TEST EACH CONTROL SURFACE ONE AT A TIME.
MOVE BOTH STICKS FULL TRAVEL AT THE SAME TIME TO SIMULATE 3-D AND GET MAX LOAD FROM SERVOS ( MOVE IN CIRCLES)
WATCH THE LIGHT ON BOTH RECEIVERS...IF ONE OR BOTH GO OUT COUNT THE SECONDS UNTIL IT COMES BACK ON
WATCH THE CONTROL SURFACES AND SEE WHAT THEY DO. REPEAT SEVERAL TIMES.
NOTE: SPEKTRUM SAFE SYSTEM MOVES THE THROTTLE TO LOW AND ALL THE CONTROLS STAY EXACTLY WHERE THEY WERE WHEN YOU HAD THE BROWN OUT...I CERTAINLY DO NOT WANT THAT ON MY PLANE...BROWN OUTS (ACCORDING TO THREADS) OCCUR DURING SNAPS AND KNIFE EDGE...DO YOU REALLY WANT YOUR CONTROLS FULLY DEFLECTED FOR 3 TO 4 SECONDS...I THINK NOT...THEY SHOULD GO TO NEUTRAL WITH THROTTLE CUT OFF (ORANGE)
NOW, DO NOT CHANGE ANYTHING EXCEPT THE Rx
INSTALL A DIFFERENT Rx AND DO THE TEST AGAIN. ORANGE, JR AND SPEKTRUM ARE ALL COMPATIBLE WITH YOUR SPEKTRUM Tx
BORROW SOME FUTABA RADIOS AND RECEIVERS FROM YOUR FRIENDS AND TRY THEM. KEEP RECORDS OF WHAT IS HAPPENING.
THIS IS A SIMPLE "PASS" OR "FAIL" TEST...PRETTY SIMPLE
TAKE VIDEOS AND POST THEM IF YOU LIKE...YOU WILL BE ATTACKED IF YOU DO. HOWEVER 90% OF RCU WILL LOVE YOU.

In hindsight after the first indication of trouble I would have re-bound the receiver,and tried again and then checked the amp draw of each servo to make sure the bec was not being overloaded.

I have a question for everyone that is a little off track. Has anybody flying a Futaba ever had any kind of signal loss or problems during a flight? This entire thread has been Spektrum failures but not a word about a Futaba failures. Is Futaba really that good?

Futaba is a good brand but nothing is perfect. Do a search on "Futaba Zero GUID problem" Some early 2.4 receivers were overheating and some model transmitters have problems with pots becoming loose in the gimbal (e.g. 12FG and 14SG )

You have quoted and thrown Jr High insults at the same post twice already. What's going on?
Back on post #6 I asked a very specific question and in post #7 you answered my question. Your answer was that the led is lit solid after your crashes and that is NOT a brown-out. In a brown-out the receiver led flashes on&off. So what exactly are you experiencing with a solidly lit led ?
Not a brown-out!

Not a brown-out!
The brown out indication (LED flashing) only occurs in DSM2 mode.
If the receiver / satellite are in DSMX mode they will recover from a brown out and the light will be solid again.
These videos demonstrate this clearly.
