'Failsafe'ing Receivers

Re: 'Failsafe'ing Receivers

I just bought a pair of those to! Dam it! But...

bought these earlier this week; http://www.ebay.co.uk/itm/130649037879? ... 1439.l2649

Just tried one in diablo running the tz85's on drive and a turnigy rc switch on the weapon and a dx7 as the tx, no external failsafes etc.... all failsafed fine first time.

Re: 'Failsafe'ing Receivers

I have a couple of those, they failsafe fine for me.

Re: 'Failsafe'ing Receivers

I used the R610 in my antweight Napalm Death.
My experience is that the throttle stays at last stick position, all other channels to mid stick. Aeroplane RX obviously.

So safe, provided you don't use the throttle.

Re: 'Failsafe'ing Receivers

The throttle fail safes, all other channels stay as is. I bought mine from the very same link as Dave!

Failsafing, the bane of my life! Don't know what else I can change.

Re: 'Failsafe'ing Receivers

Unless ESCs do something more intelligent than servos on power down?

Either way my ESCs stay as is as well!

Re: 'Failsafe'ing Receivers

My personal experience with the orange R610 receivers is that at loss of signal the throttle will revert to binding position (failsafe) and the remaining channels no longer output pulses. I'm not familiar with your ESCs but it sounds like they continue to drive the motors according to the last known good input pulse from the RX rather than turning off when no pulse is detected.

Re: 'Failsafe'ing Receivers

Yeh that's what happens.

Re: 'Failsafe'ing Receivers

In that case you would need separate failsafes between the ESC and the receiver. Back to the times of old.

Re: 'Failsafe'ing Receivers

Bleugh! I guess that is what some of the more intelligent ESCs do. Although they are the same ESCs as Galactus and Guilherme doesn't have any of these problems!

Re: 'Failsafe'ing Receivers

i use a dx6i, all spektrum radio gear failsafes in receiver only, so no differnece betwwen handsets just what they came with as before.
ar500 will failsafe i have rubbish copies but work fine
not all orange rx failsafe only rx7 its £20ish

most orange rx fail to last known position then you rely upon your esc to do the rest, ie those who failsafe with orange rxs is only probly becasue of there esc being used having auto detection etc.

this is my understanding of using spektrum in modeling for many years

Re: 'Failsafe'ing Receivers

most orange rx fail to last known position

If the RX send last known position an ESC, it will never failsafe; As the ESC never receives a dirty/no signal the ESC has no way of knowing if it should failsafe or not..

Re: 'Failsafe'ing Receivers

sounds logical, told by my local heli shop not to use them for failsafe reason , i think its called smart failsafe throttle , then others hold ?
info i was given - but defo for spektrum controllers like 610/620

i listed all the good ones somewhere will dig it out

Re: 'Failsafe'ing Receivers

I think it would be easier for me to just have a long line of string attached to the robot, then if it gets out of hand I'll just pull on it!
OK EOs?

Can you get devices that sit on the Throttle channel and tell all others what to do on power down? Something that intercepts the other signal leads?

That is how most airplane and heli RX's work, the set the throttle in a certain position and keep the rest of the channel in the last position it was when it had a good signal. Which is exactly what we do not want at all and that was why the BR6000 was such a hit for roboteers.

Yes, you can use a relay or a switch to accomplish that.

Re: 'Failsafe'ing Receivers

i had the same with the orange and some spektrum receivers so i just bought 2 of these
