D4379

I have question concerning the operation of my Spektrum in an electric jet. Though it seems to be functioning fine and hooks up quickly when I turn it on both the receiver and satellite receiver are flashing even though things are running correctly. I remember when I bound it the first time I got solid lights. Reading the manual does not give me the information about the status of the lights after binding and normal use. Does it need to be rebound again? Am I doing something wrong? I have had this system for about eight months now and have not had any issues but recent problems with another receiver got me thinking. The transmitter is the 6dxi and it did not have the recall. The receiver is a six channel and I am not sure of the model number though it came with the transmitter when I bought it.

If you remove power from the receiver in any way, and dont turn off the transmitter, the receiver is going to think it had a power failure and flash the lights.

Turn on the transmitter
Power up the receiver and you should wait about 3 seconds then the system should connect and you should get solid lights.

If you turn off the receiver (whether you disconnect the power cord or it browns out in flight) and power it back up the lights will flash but you will still have full control.

I may have an issue then. I turn the transmitter on then plug the battery in to activate the receiver. The plane comes on line almost immediately but I noticed Sunday that both lights are flashing. Even after landing they are flashing. I have been pulling the battery out of the plane and shutting off the receiver before the transmitter and it might be doing as you say. Should I rebind it again?

If you go flying with solid lights, and land with flashing lights, then you had a low voltage reset in flight.

You can try rebinding but I doubt it's your problem.

D4379

It has flashing lights from the start. I think you are correct about the brown out thing. I will try installing the battery first then turning on the transmitter.

No. You have to power up the transmitter first, then the receiver.

I think the receiver is telling you that a switch position or stick position on the transmitter is different than when receiver was bound. I have experienced this many times with a heli when I switched throttle hold on before powering up receiver. The lights would flash. If I powered up receiver with throttle hold off lights came on solid.
Hope this helps.

bingo, and give the transmitter a few seconds to 'warm up' so to speak

D4379

That is what I am doing. First the transmitter then I install the battery in the jet. Lights flashing on both receivers.

D4379

It is set up very simple and I turn it on with the position of the sticks as bound.

D4379

The transmitters are flashing but the plane functions fine.

have you tried calling the manufacturer?

D4379

Yes several times.

dont know then, never had the problem. Rebind both ways in the manual and see what happens.

You dont turn on the receiver, then turn it off, then back on while leaving the transmitter on do you?

Even something like the throttle trim not being in same position as when it was bound will cause the lights to flash. Also, if you don't quite get the flight battery plugged in on the first try it may cause receiver to loose power for a split second and cause lights to flash.

This is what Spektrum's Manual said about turning on the tx first or the rec first:
Q: Which do I turn on first, the transmitter or the receiver?
A: It doesn’t matter, if the receiver is turned on first-the throttle channel doesn’t put out a pulse position
at this time, preventing the arming of electronic speed controllers, or in the case of an engine powered
aircraft, the throttle servo remains in its current position. When the transmitter is then turned on
the transmitter scans the 2.4GHz band and acquires two open channels. Then the receiver that was
previously bound to the transmitter scans the band and finds the GUID (Globally Unique Identifier code)
stored during binding. The system then connects and operates normally. If the transmitter is turned
on first, the transmitter scans the 2.4GHz band and acquires two open channels. When the receiver
is turned on, the receiver scans the 2.4GHz band looking for the previously stored GUID, and when it
locates the specific GUID code and confirms uncorrupted repeatable packet information, the system
connects and normal operation takes place. Typically this takes 2 to 6 seconds.

Not for me it doesnt.

D4379

No but I will try to rebind it again.

D4379

Well sometimes it is a bear to get the battery hooked up and the trim settings are different then when bound. I will try rebinding again with the settings it is at now. The radio seems very touchy compared to my old 72 mhz units.

D4379

That is what I read also

it has a procedure to set it up is all. Ive been flying Spektrum for over a year, and I am very happy with it, in everything from electric park flyers, 37% Gas 3D planes, Gas helicopter..... flawless

There is one procedure to bind it, another to set the fail safe, do them both and report back.

D4379

I will this weekend.

use a separate battery for your receiver, your creating a low voltage situation. this will solve your problem.


if you have to rebind it after flying , dont keep doing this you will end up loosing your plane

D4379

I have not rebound it yet. I just noticed the last time I flew it the lights were blinking. I am not sure there is room for a seperate battery in the plane it is pretty packed as it is.

that problem is common with electric planes . you could also change the speed controller , yours is probably allowing the motor to over draw the system eventual this will lead to a lock out
