There was one guy who posted he carried it and let the body rest on his side, incase it swung around (throttle hit by accident or similar) and an image of a guy carrying it this way as well.

Well I carry it that way and I agree, don't worry about damaging the spindle. You wont bend it and if you did, you surely wouldn't want to use a spindle that soft.

Secondly,. I am left handed so I carry mine on my left side.
If the heli was to spool up, it would already be up against my side and would not swing around.

The two guys I mentioned above, well the one image, that would swing around quickly to your left side if it spun up.

If the other guy was carrying it the same side (right) it too would violently swing round 180 degrees before it hits you.

My blades spin clockwise from the top. With the head held tight the body would want to spin counter clockwise.

You righty's may want to consider carrying with your left hand to avoid this possibility.

Has there ever been a documented case of a heli spooling up uncommanded? Truly uncommanded, meaning no radio being bumped, no bad esc setup, etc. Just out of nowhere it goes off?

I have serious doubts this has ever occurred, without user stupidity.

Face it, if there were any real danger of an uncommanded spoolup, not due to user error, we'd all plug in our batteries at the takeoff point.

No way anyone would risk walking with it.

Think about that. A 7 horsepower animal just ready to bite uncommanded at any second. You going to walk with that in your fingers? You'd carry it out wearing a suit of armor with the heli in a cage like a wild animal if you really thought this would happen.

Just be diligent with the radio. I have to flick two switches to spool up, throttle hold off and then idle up 1. Normal mode has no power. I use it as safety margin. Two positive actions must occur to spool up. So far, so good. I can still count to ten.

Aaron,

Well I do mean when human error causes this (Nitro) but I have not heard of anyone using normal mode as a backup safety switch. That's actually a really "thinking out of the box" type of idea

I may have to consider doing that on my (e)heli. Not so sure it would work on a Nitro. It could work, but it may be a rather startling spin up from zero to 50% throttle.

As for it ever happening via a failure of sorts non pilot error? well I think it has a potential, but off hand cant think of exactly how that would occur.

maybe
servo link falling off throttle?

hmm that's all I got right now

A nitro bird is less dangerous in this regard. The clutch can fry while you hold it, more or less.

Electric has full torque at zero RPM and is scary when you screw up. I was luckily only mildly injured playing with my 600 being stupid, just seeing what a little blip on throttle would do while holding it. Yeah it'd mess you up. LOL. I take it very seriously, now. In contrast, I easily held my nitro 90 when I had a hot start.

I'm under no illusion that I could hold an E700 if it wanted to go WFO.

With a nitro, I'd just make sure normal mode has a nice low curve so that bumping throttle doesn't result in max power. And still carry it out in throttle hold. You need a nice spool up and ID1 won't give that to you for nitro, so you need a normal mode. It doesn't have to be much just to get it going.

With throttle hold and a low curve, it'd still take a lot for the thing to just go WFO for no reason. Still two positive actions. And if it fails you still can hold onto a nitro easier (in my experience) than an electric.

RC Heli has the potential to spool up if the Rx is initialized before the Tx.
But has this potential ever been realized or is it anecdote? Looking for a documented occurrence.

An ESC that is setup properly shouldn't initialize at all without its TX signal. The ESC looks for the low throttle signal to initialize. That's what all the beeps and squeeks and stick movements are about when we do the first ESC setup. It ensures the ESC knows what to look for from it's transmitter. And if no one knocks, it doesn't answer.

Have I accidentally plugged in a battery with the TX off? Yep. Plenty of times. Nothing happened. I don't recommend consciously doing this. If I catch myself, I unplug the RX and start over. But my point is I have serious doubts that this "potential" has ever been realized by a person who followed the ESC setup instructions.

Most ESC surprises are during the setup itself if you get the movements crossed somehow. During initial setup, I personally have no pinion installed to avoid surprises.

I'm more worried about me bumping a switch to arm the Heli while carrying it than anything else! In the OLD DAYS we did it just in case someone turned there radio on without the channle pin . You know

Do you then hand launch?

I think a blade stop hand launch would be interesting to see.

A slope soarer. I suppose you could take the engine/esc/battery out and have a real floaty slope soarer.

I really like this idea. I don't use both idle ups so this sounds interesting.

I really like this idea
Yup, I fly ID1, no dual rates, no nothing. There's only two switches that aren't inhibited, stunt mode and throttle hold, and both must be in the right position to fly. Everything else is inhibited. The gains and rates are set and cannot be changed. The pitch is set and is the same across normal/ID1/hold. The governor is tied to the ID1 switch. I paid for a lot more radio than I use, but this makes it idiot proof and there's no wonder how it's going to fly.

Keep it simple, I say. 3D is hard enough without wondering what mode am I in, am I on high rates, is the governor on, etc.

I have only one stunt mode (DX7). But if I had two, I suppose I could make normal mode like hold, ID1 like normal, and ID2 as the only mode to fly with...but then I'd lose the added benefit of a helicopter that cannot be accidentally flipped in normal mode...which is what I have now. So even with two idle ups, I would keep it simple. I'd make Normal a hold, and fly in ID1/ID2. ID1 would mirror ID2 in every way. No ambiguity.

On my nitro I settled for normal mode being just enough to get the blades going. And yet slow enough that you'd have to be asleep to not hit idle up and get up on the governor before taking off. ID1=ID2 in every way (Futaba FG8 w/2 stunt modes). This makes it similar to the electric as far as switch flipping goes.

I hate surpises and aim for absolute predicatability in my setup.

Yea, i was thinking like this: normal mode like hold, ID1 like normal, and ID2 stunt. Righ now, I start with normal mode, get heli head up to speed, then flip to ID1 at mid-stick, 0 pitch, before takeoff. No use for ID2 at the moment so it just mirrors ID1.Team HeliProz - Retired
