Effects of Pylons?

[coolice]

Hey guys.

Thought I'd do a general post for now as I'm on my phone and its difficult to do multiple quotes.

The different bind options are dependant on receiver used, I'm running AR9000's in my big birds and they allow me to set all servo failsafe positions by removing the bind plug once I have set the receiver into bind mode. I'm running an AR6200 in my 450 pro but off the top of my head cannot remember if this does all or one channel (throttle) failsafe.

Here is the AR9000 instructions detailing the two bind options;

As Waveydavey has said its not your Beastx stopping you setting all failsafe positions, but just the receiver used perhaps. Having said this all servos should have held their last known position and throttle gone to low, so why it came down hard is puzzling me as if you were hovering it would have held +5 pitch and floated down as the head speed decayed.

I'll come back later on a proper keyboard and reply more individually :-)

I will have another go. Remove Bind plug. Establish preset values on tx. Then switch on tx holding bind switch.

The cheapo AR6100 copy (sorry OEM version) from Giant Cod does go to preset values. Does it work on two channels though and will it work in my glider at range?

power lines didnt seem to affect this heli

Hey Chris.

Let us know if it works, but the more I think about this the more I'm remembering you can only set user failsafe positions on all channels on AR7000 and above receivers. The lower models only operate the throttle.

It didn't work on my AR6200. Worth a try though.

Ian, great advice mate.

Thanks buddy.

Hi Chris.

Shame, I was hoping it might but then I remembered better that this all servo failsafe is limited to the bigger receivers only.
Out of interest though when you tested to see what does happen did you main servo's stay where they last were?

I'm still pondering Max2741's as to why the model made such a big altitude change when it locked out, the model runs a one-way unit and so if the motor stops abruptly the main rotors would still free wheel and maintain lift for a few more seconds.

Had the Titan out today, no problems at all, have no idea what went wrong before which makes it hard to have confidence in it, what models of spektrum recivers support fail safe on additional serovs?

Thanks buddy.

Throttle goes to bind value and all others hold previous value. I've had loss of control on my Twister Storm due to a faulty AR6200. To be fair the vibration was excessive at the time. I was in the early hovering stage and the heli just floated gently down. Almost as if it was showing me how to land. At the time I was dislodging the boom as the tail hit the ground.

Do you know what the Rx LEDs were doing afterwards ?

Is it possible the Beast-X re-booted in flight ?

[QUOTE] there is a saftey distance from these cables of 3.1M go inside this and there is a chance it can jump the gap. Elecrticticy can jump 1mm per 1000V so 400Kv will jump nearly half a meter in dry air.. so with a bit of airborne moisture you can easy double that....![QUOTE]

Yes but like a Bird landing on the wires your model will not be subject to getting zapped. Years ago before the fun police took an interest we used to limbo the local pylons at the FWP power site and at one of the slope sites at the end of the day launch our foamies down the hill for the longest glide. The requirement was to pass under the Pylon cables at the foot of the hill which were right on our visual limit some 1/3rd of a mile away. On numerious occasions we hit them and occasionially flew on.

Where you may pick up interference is from faulty insulators on the Pylon itself as its not uncommon to see arcing at night in damp weather but overall I would think your more likely to be suffering an install related issue or similiar.

AS I undertand it with AR6200/AR7000/6100 receivers only the throttle goes to a predetermined failsafe and the other channels hold their previous positions.
If the RX loses the tx signal it initally holds all channels, then after a shoprt time it goes to failsafe.
IF the Rx loses power, then it obviously can't do anything - but if it gets power back it goes looking for a Tx - and with quickconnect it finds it quick. However in a situation where it is looking for a tx is puts the channels in the at bind position - becuase it doesn't know any better and hasn't got a posirion to hold with.

Now if you bind with left stick down, you might have full negative pitch as an at bind position. Better to have throttle closed and zero pitch.
If you have a dicky connection on power you might otherwise have a heli thats glitching full negative pitch!

Fortunately when my solder joint failed on my lipo on my nitro, and had bind wirth full negative pitch, the heli was hovering upside down - so it dod a sort of inverted auto landing leaving me only with broken blades and wondering what happened till I wriggled the power wires!

That's my understanding, but with the addition that on 'boot', it doesn't send a pulse at all on the throttle channel until it's connectd to a TX.

Quite what behaviour that results in is presumably going to depend on what's connected to the throttle channel, and whether that has just booted/inited as well.
