STORING FAILSAFE POSITIONS

Even with electric park flyers it makes sense to have a low-throttle failsafe. Sure, they don't have much energy, but failsafe pre-set is just plain good safety. So the DX6 has Failsafe.
You can set any channel you wish, but normally we just put the throttle to low position during the binding process. All other channels go to the last commanded position.

this is the web site i found it on> http://www.modelflight.com.au/spektrum/spektrum_dx6_review.htm

Maby you can set all the channels to failsafe to zero?

Interesting, it seems that at the "binding" process, you can set the failsafe positions as to where the sticks are... maybe

YEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH

nope, it goes failsafe on the throttle and whatever was last on the other channels. i personally dont care for it as its pointless trying to assume that you can get the spektrum to failsafe for any length of time, but im hanging out for the guy at RMP to test the 3 channel reciever on it and see how that turns out.

Well i have got the reply from my email> http://www.robotcombat.com/marketplace_rc_radioDX6.html

Read the big read box they have put up at the bottom of the page on there site with the radio.

stop the presses!!!

3ch spektrum that i believe does the failsafe with a second reciever for $250!!

Nuts to pistal radio's lol kill them all!!

Anywho im looking at geting the www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXKAJ2**&P=0 now.

lol death to stick radio, they must make them for giants or something... my fingers arent long enough to make the stick go to its full travel dammit heh

and the dx3 failsafes according to the position on the drive channels during binding so good for robots. the third channel button is placed wierd but i can live with that.

I wonder if you can bind the DX-3 RX to a DX-6 TX...

thats what the rmp guy was trying to do, i reckon itll work. but you only get 3 channels at the end of the day so you might as well keep the wheel radio

Theres lots of argument in the Helicopter world as to whether the "thumb on the top", or "forefinger and thumb on either side" of the stick method is more precise..

Wheel radio vs Stick Radio is probably much the same type of argument, Linux vs Windows, Mac vs PC etc etc. whichever your fingers get used to and works for you, works..

The lack of a failsafe on the Spectrum is dissaspointing. I'm hope someone finds a fix for that soon.

Failsafes might seem like a small issue on occasion to those of us who already understand the working of our destruction machines, but I can assure you that when explaining Combat Robots to someone less technically-literate (like a Venue Owner), being able to tell them that "If you turn the radio off, it completely *stops* - its not allowed to compete if it doesnt" is a big reassurance to them.

On a less-often encountered, but more important note, I know some of the builders have encountered the situation where they have been very grateful for their failsafes.. to steal a slogan.. "even If it only saves you once a year, its a Good year".

Interesting how I used to worry that PCM would reduce the safety of the speed controller failsafe, which turned out not to be the case in practice, now heres the "better than PCM" technology and it does just that.

I'm sure this could be fixed with an update to the receiver firmware. I cant see any reason why a complex, multi-channel negotiated-link radio like the spectrum wouldnt have the smarts to implement a failsafe function.

They probably just didnt realise (or care if its a tiny market segment) that Robot ESC's work that way.. except that 95% of people will probably only ever connect servo's or hobby-esc's to a receiver, so it will probably need a few "suggestions" from potential customers before they do it.

totally the forefinger and thumb on the side of the stick

it still makes me wonder why having the reciever hold the last positions would be of much use in an aircraft either...

at least its verifying that we can at least use the 2.4ghz technology in some form through the dx-3. or even better it turns out you can use the dx6 tx with the dx3 rx.. i cant see why it wouldnt work.

and i also read this great little tidbit of info on the dx-3

http://www.spektrumrc.com/Content/PDF/dx3manual-english.pdf

"Lithium BatteryYour DX3 radio system is equipped with a five-year lithium battery backup system.

This system is designed to protect and retain all radio programming in the event that the transmitter batteries drop below the required 9.0 volts, or the transmitter battery case is removed during battery changes. If after five years it becomes necessary to replace the lithium battery, return your system to the Horizon Service Center for repair
(see address, page 3."

This is what was posted on the RFL forums under the DX-6 discussion:

I've read that the range is about 1500 feet. That's fairly close to your test. In r/c aircraft that would be not good, except fo rpark flyers. For bots it would be fine if noise immunity was good. I wonder if it's true that JR is behind this, that they would mess up the failsafe that bad. hmmm.

The DX6 is a modified JR XF631 radio. It looks like the only change is the replacement of the RF board with a new 2.4Ghz transceiver board. The receiver is all new, and tiny. It is packaged in a clear plastic blister pack. The Rx is what they'll need to change the code in to get the failsafes back to par. The receiver draws more amps than a standard RC Rx, but the Tx draws less.

I've been asked not to tell, but since it's important and I didn't sign anything...

The 2.4 GHz TX board is interchangeable with the TX board in the other JR radios. Three wires and your other radio is a 2.4GHz.

I have messages in to Spektrum about the failsafes so they DO know our concerns... I don't know if we're enough of a market, but at least they know. It seems to me that the 'usual' way of choosing FS or HOLD is the right way to go no matter what the market though.

i got my dx3 from there. two recievers and 8 free AAs, good deal good deal

Had ordered one a week ago and cancelled the order a couple of days ago, Doh. what a pain but understand that some of you are dangerous

Trying to work a way around this so was wondering if this idea could work.
Using the gear retract switch to control say a servo or something that switches off the power to the robot. If it ran off the reciever battery then u could swithch it back on as well.
Still hoping a solution will be found, what about an IR switch like a car alarm, I dont know, can someone come up with a simple solution around this or what.
Its ironic its failure is its failsafe when its unlikely to glitch anyways but might be a simple solution to be had with one of the spare channel switches.

Would assume that in a robot like cobra or a rammer that it would be allowed as, if the robot only has drive to control then that would failsafe correctly. Is that correct?
