PreMade Loop Safety?

[LarrysDrifter]

Damn this topic is boring. Lets talk about ducks.


...

I have a few ducks. What do you wanna know? I agree, it has gotten boring.

You must REALLY be bored if you're reading something that bores you! Why are you reading it?

My take on the safety loops is:

"If you want to use them, by all means do so...BUT...don't mandate them."

I actually think they would a great addition for convenience of not needing to untape/retape to change props or being able to tape up well in advance of a heat. For those reasons I might consider using them. But for safety reasons I'm not totally convinced. Has anyone actually witnessed an injury to someone because a safety loop was not in use? I haven't, nor have I heard of any, but I am really curious to know. I'm certainly not proposing that there have not been any!

IMO, it's worth it simply for the ease of killing power to change props.

If you ask me, anyone picking up a dead/flipped boat should have the proper training/knowledge to not pick it up by the prop, or have their hands anywhere near the prop. Again, just my take on it, but it really shouldn't need to be there for safe operation. If there's a problem with the packs shorting, etc the safety loop won't necessarily stop it from getting worse either.

Another problem for a manufacturer would not being able to standardize them because of different size/type connectors modelers use. JMHO

To fix that, just include the 6mm bullets with large gauge wire with the loop pre-soldered so all the user has to do is solder the wires to the inside part of the bullets attached to the block. 6mm bullets will be overkill for many users, but I don't know anyone running bigger than that?

I'm the odd duck. I use an 8mm plug on the outside of my p-mono. I just wanted to lower the losses and I run 2P.

It's kind of like insurance; kinda wish you had it after you are injured. Just extra insurance.

There is always someone in our pits that has a boat run the motor wild, not me that I can recall. It sits there shreeking away while the owner is running another class.

See? That's what I'm talkin bout willis! You assume 6mm connectors. Ray wants 8's, I use 5.5's! Some others with smaller boats may want 4mm and some with big'uns may want bigger. Hard for a manufacturer to make all those different sizes not know how many they would ever sell. I suspect they would sell out of the 5.5's pretty quick as they seem to be the most popular and be left sitting on the rest of them.

But what I'm saying is that they could simply use one size (or maybe two, one for normal use one for BIG current draw), and the unit would be complete and self contained.

You would get a block with female bullets already installed, and a wire loop with the male ends already on it as well. Just solder wires to the female bullets, then epoxy the whole deal into the boat.

That way it doesn't matter what the rest of your boat(s) use, the safety loop is a self contained unit. You could be running deans on the inside, 3.5mm bullets, 6mm bullets, anything.

In Australia, safety loops are mandatory.
1.An externally fitted safety loop must be fitted which physically disconnects battery from esc.
One loop per esc is allowed
An orange or blue triangle ( >15mm sides) will visibly indicate this location.

Of course, as each class has different power requirements, the choice of size/style of cable/plug is up to the competitor....
I use 8AWG+6.5MMx2 and a 4mm spark arrestor .... on 6S2P.

If you're unable to calculate what you need , you're an intellectual risk to yourself and those around you !

Now all we need to do is get a thread/argument about how to measure a boat and we will have the trifecta of FE arguments for the year done with.

LMAO!!! Where is Doug's fishing hole... Think I'll join him

[sailr]

How would you solder wires to the female bullets if they we encased in the housing? There would need to be wires already attached to the females before they are potted into the housing. Then you could solder whatever suits ya on the wires.The only reason I'm pushing for 5.5's is that more people will have that size connectors laying around to make the loop with.

I allways buy just one size. The 6.5 Castle Bullet connectors

The word duck comes from Old English *dūce "diver", a derivative of the verb *dūcan "to duck, bend down low as if to get under something, or dive", because of the way many species in the dabbling duck group feed by upending; compare with Dutch duiken and German tauchen "to dive".
