Hi
Sorry if this has been covered before but I would like to be able to have a new rescue mode. Once activated, the heli will rescue itself automatically if the altitude drops below a preset amount, say 10m.

Am not sure if this is possible if the current sensor set does not include an altimeter. If it does it might be possible to implement in software.

Anyways I think it is the next logical progression for rescue. The alternative is to implement voice recognition in the TX and when the pilot shouts "oh sh*t" the heli does a rescue. Hahaha.

Do others think this is the way to go?

And in the next step you just have to think about Rescue and it will be activated.

Spirit is experimenting with something like this.
If it works? no idea.

There is already a wish list here in the forum!
Look here.

This is currently being worked on and by the volume and level of emphasis will control how much pitch and how long rescue is enabled.

Additional expletives following the rescue attempt should further trigger Throttle Hold and prepare servos for imminent impact.

(I'm laughing through gritted teeth!)

The common term for that is "hard deck". It's rumored that MSH is experimenting with connecting a GPS receiver to one of the SAT ports, so a hard deck may be coming. The problem with GPS altitude is that it's not as accurate as lateral position, but it may be good enough given an ample altitude setting. Also, GPS altitude is actually elevation above sea level, so the ground elevation would have to be taken into account.

msh yes is working on GPS. Alex talks about it on the free fall podcast.Sat port 2 is used for GPS or was used and there was a binding issue/soft ware bug on it.

Yes GPS is not accurate enough but a mixture of GPS, barometer and accelerometer could be used to establish a hard deck
I would argue that barometer and accelerometer would be enough but I'm not programming it.

"Hard Deck" was one of the Skookum FBL feature; GPS unit needs to be purchased separately to work with FBL unit. Not sure whether MSH will do the same or something else ....

hard deck is just the first step.
but once that is done, they could add waypoints and autonomous flight.
if everyone did that, i could enjoy safe flying at the field.

No offence but for heli?
waypoints and autonomous flying ' => that's not 'flying' in my book.

Why not use a drone for that?
Imho msh should spend their cash on something else...

But maybe that's because I still believe Sim's and training circuits is better than rescue....

I don't know what the rules about standalone flying where you are flying, but here we need a license to proof you can at least master the basics. (at least in official rc clubs)

I agree, and I doubt that MSH is heading that direction. Hard deck makes sense in the context of rescue and track plotting is not unreasonable because it's a passive thing.

Radio altimeter? That's what aircraft normally use to sense "the deck".

Radar or Laser altimeters are not all that useful for 3D flight because they have to be pointed toward the ground at all times. If someone is doing inverted flight or 3D, they're useless.

I want a hard deck because I am now trying to fly inverted circuits and sometimes I do not get to the rescue switch quickly enough or I fly so high it is hard to see any shift in the rotor disk.
I believe the ring fencing could be useful especially during public demonstrations. Not as high on my wish list though especially if you need to buy a further module to do it as I fly smaller helis.

I have local government authority to fly in the local park (usually empty when I fly). Ring-Fencing would be especially useful to stop the heli accidentally "straying" over private properties that surround it.

As with Ian, a hard deck is obviously useful as I start getting into more inverted manoeuvres.

GPS, Hard Decks, Geo-Fencing... with the separation of MSH Heli's and MSH Electronics, why is everyone under the assumption these features would apply to heli's?

Because there was an issue in the fw. In which sleeping code for GPS module communication interfered with the spectrum sats on brain 1's (brain 1's will not support it but It still had impact)

So people started to dream about the possibilities....

Its a wishlist item. Some free customer feedback. It just seems like a logical next step in the evolution of the rescue function. If the MEMs chipset used in the Brain 2 has a barometer it could be implemented in existing hardware which would be great if implemented

Could be engineered to work. Heli knows when it's level and can take a reading, then use accelerometer to track from that reference. Would be more accurate than GPS or barometer which can have a good amount of error. Plus those don't know where the ground actually is, only height with respect to sea level.

It will be an external module that plugs into the SAT 2 port.
