Vx1n & talon 90 setting low throttle

[Tomh65]

Hi, I'm currently having real problems getting the Talon on my goblin 500 to arm at low throttle, i've made sure the gov is set to inhibit and that the throttle signal is analog.

In the datapod transmitter menu i have adjusted the throttle end points so i have a full range from 0% - 100% and have followed the normal low thottle setting procedure stick at 50%, connect esc drop stick to 0% then adjust endpoint untill arming tone sounds but still had no luck.

To be double sure its not an issue with the motor/ Esc / wiring i've connected the talon to the ar7200bx on my 600 pro and was able to set low throttle without any problems. I've also brought a castle link to get the talon set up correctly for a heli setting fixed end points and soft start.

I'm using a scorpion 4020-1350 motor and 2x DSMX satellites.

Any help & advise with this would be appreciated.

Hi Tom,

The way I have always done this is set the Vortex so you get 100-100. Then plug the Speedo into SV5 as normal and power up with low stick. The controller won't arm.

Then adjust the trim (not travel adjust or sub trim) down until it arms.

This should work so long as you have a normal throttle curve.

Set your battery alarm a little bit lower.
SV5 arms when swash made the 4 bumps. I had also a problem with that and when i lower my battery alarm the problem was gone and the esc arms.
It is a safety feature.
Good luck :thumbup:

First connect a servo to the SV5 and confirm that it is moving. If it doesn't it will be either the battery alarm mentioned by rotorWIZZ or something else is preventing the Vortex from correctly initialising, most likely a signal from the receiver is missing which you should be able to see in the Transmitter Live view.

Presumably you have set the Governor to Inhibit in which case you don't need to do this "i have adjusted the throttle end points so i have a full range from 0% - 100%". This step is only needed when you are using the Vortex's internal engine governor or mix-only mode. If you are using Inhibit you simply adjust your radio throttle endpoints to match the requirements of the ESC.

Thanks for the advice but still having no luck.


I checked SV5 for an output with another servo and it worked fine, lowered the battery alarm to the min and tried to set low throttle using the tx trim with no result. Checked the transmitter live view for all outputs and looks like there working fine also when i power on the vx1n i get the 4 bumps while it initializes and then a steady blue light.

I've also tried adusting the transmitter low throttle end point to 150% so that when the stick is at low throttle the transmitter live view gives a value of -21% this didn't manage to get the esc to arm.

Does it work with the esc channel straight into the receiver? Just to check if its a vortex or esc problem.

[Tomh65]

I'm using 2 dsmx satellites as receiver. To check if the esc was ok ran it through my ar7200bx and it all set up and ran fine. Problem seams to be getting the talon to recognise the throttle signal from the vortex.

I'm going to try the set up in a different model memory to see if this make any difference have had issue with the throttle output channel on the dx7s playing up before now i think about it. (Changing the model memory made no difference)

[rotorWIZZ]

Hope it works out fine now :thumbup:

[Tomh65]

Just been trying again to get the esc to arm and noticed that after the Vx1n has done the initialisation red/ blue flashing the status light flashes single violet then turns to steady blue.

Could this have anything to do with the problem I've been having?

[Angelos]

The violet light just indicates that the Vortex is accessing it's internal memory that holds configurations parameters, etc.

We have used the Talon and it works fine. There is no compatibility issue, just need to do the right adjustments. Make sure:

1) In setup menu the governor is set to inhibit
2) The throttle servo type is set to analog
3) If you plug a servo to SV5 it moves when you move the collective stick

Then just adjust the radio's throttle endpoints (not the Vortex) until the ESC is happy.

Thanks for the help, the set up is as above and SV5 is operating fine with a servo. Adjusted low endpoint from 0-150 at mid stick / low stick etc but no joy.

Would a factory reset be worth a try? Also when doing the inital set up would the point at which the esc is connected to the vortex make any difference?

[Angelos]

Give me a ring t tomorrow at the number shown on the Spartan Online Store. If possible have the heli in front of you.
