What receivers do people use that fail safe properly? The one that I've got currently [Spektrum AR6200] only failsafe's on the throttle channel.
Its intended to go with a Spektrum DX6i if that makes any difference.
Thank you in advance :)

I run a OrangeRX with a DX6i. failsafes two electronizes 30a no problem.

I'll second the OrangeRX suggestion. I use both the R410 and R610 models with a DX6i and they failsafe properly.
Right, that's perfect :) One more problem solved Thanks guys
I think for the Spektrum range it's the BR Rxs that fail safe on all channels, but someone else will have to confirm.
Can the UK techcheckers confirm that the orangeRX receivers failsafe or cut signal on all channels? Are they acceptable for heavies as well?
My OrangeRx has all sorts of problems failsafing, in that it doesn't.........
I run several orange RXs as all my AR500s failed after a year or so. I started in the feathers without issue, i've since been running Kronic on one for most of this year (with the added satellite) and until Guildford last week i had never had a problem, but i had a major mis-firing problem there. The fault might be something else and nothing at all to do with the RX, never had the fault before, will probably sawp the radio gear for something else then see if its OK.
Never had a problem with it failsafing though, always worked first time.
my futaba only failsafes on the throttle channel, so i wired it to a switch on the tx so it
controlls my watty on/off and my weapon relays. now its my failsafe and my robot off switch .
Leo- at the fw uk champs... Everyone using orange rx's fail safed fine during tech check.
However, most people using dx6i's had problems.
Leo- do you have any experiance with the walkera devo 12 tx? I'd like to buy one but can't see any info on failsafe positions.
Where are people getting there OrangeRxs because the one I have just stays in it's last known position when I power of the Tx, ie. Full throttle.
What kind of problems with the 6DXi ?
Im looking for a new tx setup, my cheap ass set failsafe's good, but sometimes has a hard time linking up, in busy environments.
I have used spectrum DX6 (3 off) and DX5e (3 off) plus the Technobots Saturn radio and had no problems, the only thing I have had to watch is the controls and trim positions are in the place I want for fail safe, before I bind the radio. I do try to insulate the Rx from shock and vibration perhaps this helps.
Craig DX6's are great for robots, but unfortunately there now old hat and all DSM1 rx's are getting hard to come by...
Jeroen - I'd suggest a dx7, I use one for my rc plane/robots etc and it's great... Plus it works with DSM2 rx's and it failsafes on all channels, also are a good price on eBay now. Dx6i I'm told only failsafes on the throttle?
I think it's Rx dependent.
I also discovered that DSM Rx output a false signal on startup and then revert to where your sticks are, which ruins any calibration on the ESC since they pick up this false signal.
It also rather worryingly means the ESCs can output power (wheels or weapon!)
Thanks Dave DX7 fail safe on all channels that's useful info, though I will probably keep the old stuff till it breaks! I have just now done an aerial mod on the DX5e were you put the aerial in the RX case so it won't get broken.
I did a test on Tron and worked a treat.
I'm sure it will reduce the effective range but for robots that's not really a problem, test it for real at Leeds :D :mrgreen:
Good mod that, I thought about doing it to mine... I remember woody posted a link years ago to a rubber duck type aerial mod, tried to find it before but failed.... So woody if you read this.... :p
I really think the failsafe part is in the receiver, not in the transmitter.
I do not see how the DX7 would preform better than the DX6i, it is same technology. The DX7 is more advanced for as far i can judge.
In my opinion both are overpriced ;).
Where do people get their OrangeRxs?
ebay
hobbyking and ebay
Just checked my Ebay purchase history and the OrangeRx I bought doesn't state whether it's R610 or like wise, so may have been a rip-off hence not failsafing.
I'll try buying another and see if that makes any difference.

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.
Cheers Dave! Failsafing seems to be the bane of my robot life!
Because you're using electronize :P
Not once have I had a failsafe problem with Electronize, Mr!
This is in BitzaWood which have some £13 controllers from China. On Tx power down they just stay where they are.
BitzaMk2 seems to have completely arbitary conditions that means the drive failsafes, it was just lucky the case was true at the time of the champs.
elextronize are easy to failsafe, the more annoying part is getting them to work together nicely :p
Just bought these:

They don't failsafe! Throttle channel does, but all others just stay where they are on Tx power down so the bot just keeps on driving....
Using a DX5E, just trying servos at the moment to see how it performs.
Any suggestions on how I can get this to failsafe?
I just bought a pair of those to! Dam it!

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.
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.
Unless ESCs do something more intelligent than servos on power down?
Either way my ESCs stay as is as well!
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.
Yeh that's what happens.
In that case you would need separate failsafes between the ESC and the receiver. Back to the times of old.
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!
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
