Strange Spectrum problem
i have something that just happened to me and i thought i would get on here and see if there was anything i might have for got or maby even over looked
1st a little history i have been changing all of my radios over to the spectrum system i the AR-6200 and AR-7000's i bought 4 receivers a few months back and i replace them as needed ( depends on what heli i want to fly ) i have replaced all receivers as of today the last receiver was a AR-7000 that i placed in my JR Ergo Z-230 Gasser now here is where things seem to be going wrong....
1 i removed the old receiver and installed the new AR-7000 then i bind ed both the receiver and transmitter everything looked fine as all lights were on i then i made sure the servos were going in the right direction ... no problems at this time was observed..
2 now after a full 18 hour charge and a quick check of the battery with a volt meter it is over 6 volt almost 7 volt which is what i would expect i could not check the mah but it should be at the 4500 range or more ... the helicopter is still on the bench and not flying as of yet ..
3 i am now ready for a test flight so i take the helicopter in the back yard ( this is where i fly all of them for the first time that way i don't have to take every tool i have to the field ) i place gas in the heli. i then turn on the radio transmitter then the receiver just as if it had the 72mkz radio in it . At this point i see the saddle light receiver blinking so i though that to be strange as i have never seen this before after it is energized. it then stops so i continue on to the next step .
4 i pull the starter to crank the Gasser and just when it fires the lights on the receiver go OFF as if i turned the power off ?? i turn off the heli and then i turned of the receiver and transmitter then re-energize them and everything is working once more i then decided that i need to do a recheck of the system so its back to the bench i pulled the receiver and checked all the wires i checked the servos and there wires i then placed the receiver back in and i did a rebind just to make sure everything was good to go.
5 back to the yard once again i filled the heli and did all the checks even a range check every thing is a GO .... i pulled the rope and the heli was running it was slow so i gave it a little more gas with the trim and it was now as smooth as can be.... THEN all at once it started to pick up RPM's to about 1/2 throttle and the lights in the receiver were out ?? so i had to shut off the helicopter with the run stop switch . i turned off the receiver and back on and it re-energized so now i have changed the battery out and it still does the same thing the only thing is THE GYRO ALWAYS STAYS ENERGIZED. so i can assume the switch for the receiver is ok ? .....
again i have checked every wire and every connection i have also replaced the battery and i have re- bind ed the receiver 4 times i think my problem is the receiver and i sent a email to spectrum i know its a Holiday and it will be tomorrow before i get a response from them but i thought i would ask and see if i might have missed or over looked something ?

RE: Strange Spectrum problem
Having a similar problem with an AR6200. Have tried 2 known good batteries and at some point both receivers must loose power becauce when I land both are slowly blinking as if had been subjected to low voltage. The heli has almost been lost 3 times and all on landing. Once it piched nose over even with full back stick, same thing to the left, and once throttle hung at hover speed. this has always been close to the groung and I was able to recover the heli before disaster, but it is grounded til I hear from Horizon I have had NO problems with the same TX and the 2 AR6100es I am also flying. I am thinking about putting one of the 6100s in (keeping it close in), to see what happens. I can find nothing wrong with the rest of the heli.

Mine is a DX6i, the receiver came with it, both are less than 6 weeks old( actually the 6200 was just put in service last week).

RE: Strange Spectrum problem
mine has its own power. the receiver is the only thing that needs power and i have a 4.8 volt 4500mah battery for that i pulled a receiver from another helicopter and it works great i had a strange i guess you could call it a glich the radio wouldnt work for a few seconds i have since found that the servo wires where to close to the coil so i have it back on the bench and i will move all the wires later tonite and test it tomorrow but i did send the other receiver in to be checked just in case it has a problem.

Which DX are you using? The older Dx are not compatible with DMS2 systems such as the old DX6.

RE: Strange Spectrum problem
Update to the strange problem ... after i sent my receiver in thinking it was bad i then i took a receiver out of a helicopter that was flying and it did the same thing as the new one so now the search was realy on to find just what the heck is going on so here is what i did ...
After checking every connection and moving every servo wire to a new location when i would pull the rope on the starter the lights on the receiver would blink once the Z-230 started the lights would go out if the receiver was mounted so i took it out and let it hang to the side by doing so it would stay on ? but if i got it close to the front of the heli where it is suposed to sit it would shut off and i would have to kill the motor i then checked every screw that was on the helicopter to make sure it was tight thinking that some form of RF was taking out the receiver i could not find any thing loose so as i sat the heli on the table i began to think what would cause a electric falt or some RF of sorts i then began to look at the coil since i have been a mechanic for 35 years and i have seen some strange things but it wasnt leaking when running so i then thought some more and i then relised that the spark plug was the only place left i then removed it to find that it was not a restore plug i went to the local parts place ( NAPA ) and bought a new one to replace the the old plug after a few minuets i was pulling the rope and the helicopter was running and the lights on the receiver stayed on i then moved the receiver in place while it was running and everything was golden as i placed it back to where it should be i then tested it for a close hover and no glitches i then let it idle and did a range test and everything tested fine and no more problems .... its kinda strange as the old receiver 72mkz didnt mind a non resistor plug but the spectrum did so if you have runaway check your plug.
