Fail safes

[tracerbob]

I'm looking into fitting some of my boats with a fail safe. Whats the most popular ones out there and what features do they have? I'm using Futaba and JR radios.

I have put my Hitec HIS-03MK programmable reciever to the test with both week signal and low reciever voltage. It worked great and did everything that a failsafe would do. It also has a LED that is color coded for reciever pack voltage (it will detect 4.8 packs and 6.0v packs and adjusts accordingly). Way cool from my point of view. A three channel FM reciever for just $50. Also for your JR/ Futaba situation...it will detect the different shift between those radios and will shitch automaticaly.

Dont just look into putting a failsafe in your boats, DO IT.

I have used the venom, dyamite ones. Both are plug in and set. works well for the price, My futaba radio came with a built in failsafe and works well. Low voltage, and never had it go out of range and kick in, but it works.

I have found on some radios, if you get a glitch or spot where signal is weak it will trip your failsafe for a quick second and or kill it completly.

That's always been my complaint about failsafes and why I would never use one. My two cents.

I'd prefer one that would kick in at the first sign of trouble and then resume normal operation when the problem passes (if it does) so I don't become deadwood for everybody to use as a ski jump :blink:

Maybe I am loving my Hitec too much here, but it gives you the choice to have the servos hold the last position or a preset positon like idle or off.

Preston, I respect your opinion but consider the alternative. I don't like "running up on the hill" seriously damaging the boat or having the thing running wildly in circles until it hits something or gets hit. I once witnessed an F rigger at a Jacksonville race come off turn 5, head straight for the bank WFO, launch itself into the air (after going through the safety net like it was'nt even there) and take out the back window of a van. I agree it's a pain in the butt to lose a heat because the fail safe tripped. That's why I've posted this question to see which one works the best.

You are absolutely right. As for the net, not much of a safety net.

This is getting off subject a little but WTH. A good question is, "How does one set the failsafe?" If you set a failsafe to do anything other than shut off the throttle then you are only unleashing a moving object into the potential path of others or it's own pontential doom.

I have bunch of boat, would never think of running one without a failsafe. I've tried different ones, best I found for the money MPI. You can ge them from Gary Preussse, 630-279-2451.

Fail safe are designed to shut down the carburator and it turns the rudder hard right. You will not be able to resume running the boat, as you want, you will have to go retrieve it. Don't know of any failsafe that will do what you want.

From what I have seen failsafes are set by the operator as far as servo defaults, and that is just for the throtle (or what ever servo that you plug it in line with.) That is for the venom, dynamite, and XTM as well as my Hitec reciever!

My opinion...failsafe for a play boat,no failsafe for a race boat.

 

[tracerbob]

Maybe what I'm looking for in a failsafe dosen't exist. <_<

If you use a fail safe you have to accept the consequences of the device.. to me if you are going to use one the only thing that makes since is to have it shut the boat down.. if anybody hits the boat its not good but it is racing however..

To me its not a boat saving device.. its a people saving device..

When a boat goes out of control its a bad deal either way.. I just dont want anybody getting hurt.

O yea.. Having said this i do not use them..

This might come off all wrong but I feel like the racers that are attending the event need to be as responsible as possible for their presence. They know the danger of the boats. Its not needle point we are doing here.. They are machines, all machines fail.. it’s a fact. .its going to happen. Its just the way it is..

Ask:

NASA

NASCAR

Ford… now im picking on some of you

Boeing

Ron Popeil (the man )

Futaba

Others.. all others..

This is not entirely true. I don't know how those add on failsafes work but the one built into my Futaba 3PJS is programmable, you can set it to your own specifications. And yes, I've had it failsafe & come back on one of the extrememly rare occasions it was activated....... :blink:

I just set mine to return the throttle to idle.

Lets clarify the original question. Of those who choose to use a fail safe, which brand do you use and what kind of features do you like about it?

Factory Futaba built into the 3PJS. I like it because it's failsafe settings can be programmed where you want them & unique settings to each boat in memory.

JR-1 PCM, with a Z-PCM reciever you can program a delay into the failsafe, .25, .5 or 1.0 seconds delay until the failsafe kicks in. This allows you to drive through a glitch and then it "comes back on" You get what you pay for! It also controls all 3 channels so you could easily wire a kill switch in for gas boats.

The New S-PCM receivers don't get the delay feature.
