I think the radio itself, the TX and receiver are great and mostly immune to radio "noise", however your servos and speed control may not be. Range check and use good maintenance and installation techniques and you should be fine.

All radios are subject to radio glitches caused by static electricity. The tail drive belt is a static charge generator if the conditions are correct. Spraying the belt with an anti-static spray will help this.

It's OK....It's not your fault !!!

I have a DX6 and the AR6000 on my 450. I thought I had the same problem over the past few weeks! I even went and bought a new RX thinking the old one was damaged? I binded my heli and then did a range test after buying the new RX and it seemed to work fine. I took the heli out of the hangar and flew it around outside a little and it's like it went into a fail safe and came down to the ground. Did another range test and the heli was not receiving the signal. Couldn't be the new RX?.....

So I took the TX apart and found my antenna wire was unplugged!!! I guess this is why it would work close and would lose contact while the heli got further away? Plugged it back in, range test and perfect now!

Don't wrap the wires around the frame thinking you're going to make it look cleaner! I did and the servos starting twitching with interference!

Good Luck!

I had multiple hits when flying the DX6/AR6000 on two different TREX's. Always a large tail kick,with an occasional power interuption (motor). The Futaba 401 would reset in flight, making bringing it in and landing it a bit sporting (holding over half stick to keep it relatively straight).

I tried external BEC's, thinking I was experienceing brown-outs, but this had no effect. Using silicon spray on the tail belt did not help either. Swapping one ship to 72 MHZ corrected things (not the solution I wanted).

Swapping to a DX7 transmitter on the helicopter with that had the DX6, while retaining the original AR6000 rx cured that helicopter.

I have not used the DX6 since.

DX 6 works fine, used one on a 600E for a while...Key here is the range check...Most people new to these radios don't seem to do this correctly...The ant to the tx was unplugged? Couldn't have passed a range check...

JOhn.

I did do the range check from 30 paces away and while depressing the binding button on the back of the radio - per the instructions - after buying the new RX. All controls functioned - but 10 minutes later while making a turn the heli dove nose in to the asphalt!

RAK402, I have identical problems that you described. Did you modify your DX6 in any way? I recently did the 3.3 voltage regulator (Dimension Engineering) modification and I think that is when my trex started exhibiting the exact symptoms you described.

Sounds like yours was the TX. Just curious if you had modified it.

Thanks,
Waff

Waff,

My DX6 is bone stock. I had it in several helicopters (including two TRExX450's, and several airplanes.

To correct the problems in the TREX's (both of which behaved in exactly the same way) I tried:

1) Moving the reciever from the back, floor of the frame, to the front, under the battery shelf.

2) Orienting the antannae different ways.

3) Silicon Spray on the belt

4) Adding an external BEC

None of his had any real effect. I did not get the glitch every flight, but at least as often as one out of three flights. The whole machine would jump, the motor would drop out, the gyro would re-set. Both TREX's exhibited the same symptoms.

One was resolved by upgrading to a JR 10X with an AR790. All glitches ended. The other, was corrected by just changing to a DX7 transmitter, while retaining the AR6000 reciever (again all glitches ended).

The 10X, by the way, has itself been upgraded to 2.4 via Spektrum module. The reciever in that TREX has been upgraded to an AR6200. The radio link is completely solid in that one still.

I do not, by the way, believe that all DX6's are inherently bad. Mine worked fine for a while, and I did accumulate several hundred flights on it.

I am just not inclined to try to use it again, at least not in a helicopter. The DX7 was a huge improvement, not only in the radio link, but in the CCPM response, speed and resolution.

Thanks for the quick reply. I have had my DX6 since they first came out. I have had hundreds of flights on my airplanes with 0 glitches. I now use it on my Trex 450. The first few flights were no issue.

Lately, I get the tail jumping. I just rebuilt the tail, gears, belt, etc. because I thought it was slipping. Now I have noticed it is not only the tail but the motor appears to cut out for a very short time. Less than 1/2 second. I don't know if the gyro is resetting, I don't think so.

I have not had anything get out of control, but it is un-nerving. I had a few hits on my first pack today, the next two packs were hit free. Most of my hits happen very early on when I start. Maybe it has to do with the radio warming up. not sure.

I guess if this kind of thing happened on my airplanes, it may have gone un-noticed. Kind of hard to miss on the trex though, when the tail jumps.

I was running an Eagle Tree datalogger, so I will check later to see if anything looks unusual with the voltage. I am running an external BEC.

My problems are definitely not brown outs, they are very momentary, quick hits.

Thanks,
Waff

"My problems are definitely not brown outs, they are very momentary, quick hits."

Exactly what I was experiencing-definitly not brown outs!

I think I solved my "hits". I relocated my ESC wire that goes to the receiver. It used to pass very close to the motor & plug into my stand alone BEC. Now I routed it back away from the motor straight to the receiver, bypassing the BEC. So far, 4 flights with no glitching.

So, I have changed two things here. I routed the wire away from the motor and I no longer pass through the BEC but directly to the receiver. I think of the two changes, it was more likely the re-routing of the wire away from the motor.

Anyway, so far, so good...

Good post...suports my contention that many of the "issues" with Spektrum are not the RADIO at all, but emi passing from the wiring into gyro, servo, especially esc...Which can then shut down momentarily..That still isn't the RADIO.

JOhn.
