anyone have it runaway when it loses sight of the transmitter?if the transmitter is off and you turn on the esc it goes 10mph don't remember that happening before.the neutral percent does nothing,,,,,,,,thanx

You need to add a fail safe to the mix. The loss of signal will do nothing to the ESC. It's the receiver/fail safe that does that function.

 

[mechanike]

the failsafe is built into the flysky receiver which will apply the brake on the throttle/brake2nd channel.the esc is plugged into that 2nd channel port.

 

[wacmartin]

Have you ever set/calibrate the failsafe? I know my radio system you have to calibrate it yourself.

 

[Greywolf74]

You have to set the failsafe before it will work....found that out the hard way once.

 

[mechanike]

the failsafe thats built into the flysky uses the 2nd channel port which is taken up by the three wired plug of the esc.so there is no option for failsafe with the flysky receiver unless it was a nitro that you can put the throttle/brake servo in channel2 port,,,,,,,,,,,,or am i missing something,,,,,,,,,,,,thanx people.

 

[wacmartin]

I don't understand, if it's built into the radio why would it need a port to plug into? If it was an external/in line failsafe then you would plug the esc into the failsafe then the failsafe would have a plug on the opposite end to plug into the receiver. I've never used a in line failsafe so I'm not 100% sure on that.

You turn on your kit. hold the brake all the way forward and you take a small pin or micro screw driver and you press the Failsafe button until the led flashes. Once thats done the failsafe is set and if the RX looses signal from the TX then it will send a signal to the ESC via channel 2 to engage the brake and keep it engaged until the signal is reestablished. You can test to make sure its set properly after youve set it by turning off the TX and see if the brake LED on the ESC lights up.

exactly what grey wolf said. as for what is pluged in to your 2nd ch it is normaly your speed controller that plugs in to the 2nd ch and servo into your 1st ch the failsafe is built in to the receiver. when you get it setup test it by holding the throtle alittle bit and turning you esc off and see if the wheels stop or keep going. let us know if this helps.

my brake servo has to be plugged into channel three.i am also using a cyntrifical clutch on the motor so i don't have the option of using the motor brake maybe thats the problem?thanx all once again,,,,,,,,,,,,,the reason why the receiver loses sight of the transmitter is that the hobbywing80amp esc just started popping the flysky receivers so low and behold i'm running along close by then wherever the steering is set when it disconnects, it runs away in that direction.i have a seperate failsafe somewhere,if i plugged it in and activated it would it apply the brakes in channel three?channel three is only an on&off that is activated by pushing the side button on the handle,,,,,,,,,,anyone else have had the problem being that the esc now likes to spin the motor at 10mph when it loses sight of the transmitter? it will start burning the clutch shoes so i'll just have to run over and shut off the receiver,i need the workout +its way better than a runaway,,,,,,,,,thanx

 

[Greywolf74]

You post doesn't make any sense. you're talking about having an ESC and clutchshoes....Electrics dont have clutch shoes and Nitros dont have ESCs so I'm confused at what you even have. I'm also confused as to why you have you brake set up on channel 3. Maybe if you showed us so pics so we can get a better idea of what were dealing with here it might help.

Sounds like he is running a converted nitro. I remember seeing one somewhere else, and the guy had clutch shoes on an electric.

Mechanike, why not just run a pinion and use the motor as a break? I would be more concerned about my ESC killing my rx though, I'm pretty sure no fail safe will work once a rx is dead.

 

[smkynutz]

What kinda rig do you have?
Does it respond fine while it has sight of the receiver?
When it loses site, does it idle down and them make the rig go slow?

10mph could be idle.

Thats what I thought at the beginning but his last post says he has a clutch. I've never heard of putting a clutch on an electric motor and if he doesn't have an electric motor than he doesn't need an ESC...

 

[SchrodeMode]

I know Tekno makes an adapter

 

[hamz9561]

Tekno makes electric conversions for nitro. These use the clutch from the nitro for compatibility.

 

[mechanike]

yes it appears just to be the rx.and yes to the adapter shown for adding a standard clutchbell+shoes.totally cool.i can drive this 50+mph beauty around at 2mph or less in the house!totally controllable.people think it will slow it down or its just another part to wear out fast,not true so far,,,,,,,,just looked at the alum.clutch shoes and they look great after at least 4 hours of harda$$ running!the clutch actually appears to act like a torque multiplier.+it also appears to act like a soft start which appears to help keep the drive hubs from notching+generally easier on the drivetrain.

 

[fescue101]

the failsafe has nothig to do with the esc, motor or the clutch. the failsafe on the flysky tx is all about programing the recevier right.i dont think there should be a plug for the failsafe either becasue it is programed in the receiver.check out this video on the flysky bind and failsafe setup.

 

[mechanike]

some pic's thanx people all straight except if i can use a seperate failsafe to operate a brake servo in the 3rd channel,,,,,,,,,,,,,,,,the failsafe in a good rx don't runaway anymore but has to roll to a stop.thanx for all you guyses help,,,,,,,,,,,,,

 

[fescue101]

have you try to program the rx like it said in the video? it should still work to at least make the motor stop and not have any movement and be in neutral.plug the esc in to the 2ch and try it again.
