have align/telebee gyro plugged into rudder channel and gain plugged into gear channel of r700 rx.. turn on radio and then turn on heli.. after few seconds gyro light pops on.. but when i move rudder stick left or right nothing happens, try switching gear switch for hh and non hh.. nothing !!

but when i turn off radio and heli.. then remove gain wire from gear and plug it into aux2 of rx.. turn on radio then heli wait till gyro light comes on.. then remove gain from aux2 and plug it back into gear everything works perfect.. left and rudder and i can switch from hh to non hh with gear switch

what am i doing wrong !!!

setup.. trex450 hde, align/telebee gyro, tx- jr xp662, rx- r700, align esc & motor

Sounds like you don't have your radio programmed for gyro gain on the gear channel but instead it is programmed to be on AUX2. Don't have that particular setup so can't tell you how exactly to check that. Maybe someone with experience with this setup can chime in. On most radios there is a menu to assign the gyro to the gear channel or the AUX channel. Not sure if this is your issue but thought I would throw that out there.

even not doing anything would have been better than nothing...

Do you have your switch selection set right?

weird gyro proplem
yes.. i have the gear switch selected to F,, also the gyro does not function in aux2.. when heli is started with gain plugged into aux2 then removed and plugged into gear.. everything fuctions as it should but if i restart heli with gain plugged into gear it stops working

Are you waiting long enough for the gyro to initiate, the tail blades twitch.

yes.. i wait till gyro light is solid

what ever signal aux2 channel is sending to gyro when it powers up and initiates makes it work..

I've been trying to come up with something but at this point I'm wondering if you shouldn't remove the rx from the heli and test all the channels separately with a spare gyro for proper functioning. It is not beyond the realm of possibility that the rx is defective or malfunctioning. Truly I would think unplugging the gain while the gyro is powered up should confuse the gyro, but it sounds like the opposite is happening.

So I think that verifying the rx, radio, and gyro for proper functioning in a more controlled environment might lead you to a solution. This is very weird indeed.

even not doing anything would have been better than nothing...

try this instead of setting it up as a gyro gain channel leave it as a regular channel and set endpoints to be gain

Sorry man I said spare gyro but I meant servo. If no spare servo I would try the end point config Voodoo suggested.

Its not lying on its back is it, they work better standing up. I dont know why, attitude should make no differance with a gyro, but the two times I set one up they wouldn't work unless they were upright ?

tested with different sevo.. same problem

gyro is upright with sticker on it's side

does anybody know what the aux2 is for on a r700 rx.. it's a 7 channel rx but aux2 would be a the 8th channel,, the instructions don't show a aux2 channel or say anything about aux2

If you are really using a JR 662 transmitter, you cannot use AUX2 out of the receiver, that would be the 7th channel. Your TX is ONLY a 6 channel TX. There is nothing coming out of the TX to control AUX 2.

The AUX2 RX output is only usable if you have a 7 or greater channel transmitter.

When the 662 is in HELI mode, you don't HAVE a "GEAR" switch anymore, as that switch becomes reassigned to become the FLIGHT MODE switch function.

You MUST plug the gyro gain lead into channel 5 of the RX. If you have set the "GER" menu setting to "F", then you adjust the gain of the gyro using the GEAR channel endpoint setting menu. You'll see that when you flip the Flight Mode switch, that you get one setting that goes from 0 to +150, and one setting that goes from 0 to -150.

The R700 has seven channel outputs:

1. Throttle
2. Aileron
3. Elevator
4. Rudder
5. Gear/Gyro Gain
6. Aux 1 (Collective pitch in heli mode)
7. Aux 2 -- not available when teamed with a 6 channel TX such as the 662.

Aux 1 is channel 6

Aux 2 is channel 7, only available if you have a 7 or greater channel TX.

Aux 3 is channel 8, only available if you have an 8 or greater channel TX.

Aux 4 is channel 9, only available if you have a 9 or greater channel radio.

I'll assume that your gyro's gain control also selects operating mode (HH vs Normal/Rate mode). If you use the Flight mode switch to control the gyro's gain and mode, then unfortunately one of the flight mode switch positions will select HH mode while the other will select Normal/Rate mode. You may not want that kind of operation.

If you want to keep the gyro in HH mode (or Normal/Rate mode) regardless of the Flight mode switch position, then you'll need to assign the "GER" menu to either "A" (Aileron Dual-Rate) or "E" (Elevator Dual-rate) switch control. You wouldn't want to assign it to "H", as you probably don't want to change gyro operating modes when you go into Throttle Hold. If you choose "A", then the gyro gain is controlled by the Aileron Dual-Rate switch. If you choose "E", the gyro gain is controlled by the Elevator Dual-Rate switch.

No matter what switch you end up using to control the gyro, you'll be setting the gain and mode in the GEAR travel menu. Note that when you're in the GEAR travel menu, that the switch you've assigned to control the gyro is what allows you to select the 0 to +150 setting, or the 0 to -150 setting.

If you DO assign the gyro control ("GER" ) to "A" (aileron dual rate switch), then you'll want to select "E" or "CF" in the "D/R SW" menu. If you choose to assign gyro control "GER" ) to "E", then you'll want to select either "A" or "CF" in the "D/R SW" menu.

-----

If the gyro did something funny when you switched the HOLD switch, then you either have the gyro gain control being selected by the HOLD switch ("GER" menu says "H" ), or your rudder trim in HOLD mode is not the same as that of the other two flight modes.

ALL RUDDER TRIM settings MUST BE IDENTICAL, or switching between flight modes (including HOLD) will change the position that the gyro memorized as neutral at power-up.

The 401 MUST be initialized in Heading Hold mode (the red LED will be on SOLID after initialization if you did this correctly. If the red LED goes ON solid, then starts to blink when you change flight modes, it means that your rudder trim in that flight mode is different than that of the mode in which you initialized the gyro.

The red LED will flicker/flash as you move the rudder stick, and will return to ON when you stop moving the stick. The red LED will go OFF if you switch to NORMAL/RATE mode operation.

My 662 has long been retired to nothing more than SIM duty, but I still have it around, as well as the manual. I bought it new back in 1997, so that radio has been around awhile. I wonder if his is ready to have the internal memory keep-alive battery replaced yet?

It was pretty weird that no one seemed to pick up on the fact this poor fellow is trying to control his gyro using RX channel 7 with a six channel transmitter.

Ain't gonna happen, no way.

Hope the post helped sort out his troubles.

im not trying to use aux2 to operate gyro.. im using rudder channel for gyro and gear channel for gyro gain and rudder servo plugged into gyro.. but it will not work !! the gyro will initialize but i get nothing no rudder control left or right and gyro it's completely dead.. but if i power-up heli/r700 receiver with the gain wire plugged into aux2 and keeping gyro in rudder channel and wait till gyro has initialized (light on gyro turns solid) then remove the gain wire from aux2 and plug it back into gear channel on rx everything works as it should.. i have left and right rudder control and i can switch from hh to non hh with the flight mode/gear switch

the gyro im having these problems with is align/telebee gyro

i tested radio and receiver with gy401 and everything seemed to work as it should.. but i noticed when switching the trottle hold switch it made the rudder servo move it position.. don't know if thats normal or not,, im just begginer

thanks.. i appreciate everybody's help in trying to help me solve this problem

Does this Align gyro have a model or part number by chance?

Still figuring out what to do with my 662 and R700 RX to help you.
