Failsafe inquiry

[Phil Young]

Good morning all.
I’m having trouble setting up the Failsafe operation on my Elefant. Having set up Failsafe on my other tanks, I thought that this would be a formality.... but, when testing, the servos operating gun slew and elevation return to preset positions immediately ok, the tracks continue to turn. I realise there maybe a short delay before they stop, but they don’t stop until I switch the tx back on.
So... when in doubt and frustrated that something doesn’t work as it should, what do we do?... We consult the instructions that we’ve probably threw to one side when starting out!
In this case it’s the Knowledge base. Now I’m a little more confused. The information says to remove the bind plug twice?
Could I ask for clarity and assistance in solving this annoying problem?
Regards,
Phil.

Hi Phil.
Start with tx and rx switched off.
Put the bind plug in the rx bind port,
Power up the rx,
Press the bind button on the tx and power up the tx,
After a few seconds you should get the bind complete message,
Remove the power from both rx and tx the remove the bind plug from the rx.
Job done, the rx and tx are now bound together and the fail safe can be checked.
Regards
Steve

Which transmitter/receiver do you have ?

Hi Adrian
I’m using a Spectrum DX6 with a AR8020T receiver. I had no problem with my King Tiger using a DX8 with a AR8010. Just confused that the servos respond to the Failsafe programming but the motors don’t?

Reading the AR8020T manual, it says:

"Smart Safe + Hold Last is the default setting on the AR8020T. Preset Failsafe and SAFE Failsafe are only available through forward programming."

Then:

"SmartSafe + Hold Last
If loss of signal occurs, SmartSafe™ technology moves the throttle channel to its preset failsafe position (low throttle) that was set during binding.
All other channels will hold their last position. When the receiver detects the signal from the transmitter, normal aircraft operation resumes."

So it sounds to me, if the motors are not on the throttle channel, they will be held at the value which was active when signal was lost.

For all channels to be set to a default value, it looks like you need "Preset Failsafe"

"Preset Failsafe
With preset failsafe, you can set the specific control surface positions you want to use if the signal is lost. When the receiver detects the signal from the transmitter, normal aircraft operation resumes. Only available through Forward Programming"

Hi Steve and Adrian
Thank you both for your helpful suggestions.
Steve... this too is my normal way of binding/Failsafe, but wasn’t having any luck.
Adrian... after reading your reply and re-reading my receiver manual, I now understand why the Failsafe procedure wasn’t working with the AR8020T receiver.
I have now fitted the AR610 receiver from my Tiger 1, which is undergoing a full refurbishment and can report that Failsafe is working fine!
Many thanks again for your help!
Phil.
