So,

As many here say at some point it seems as though your P3 is going to drop out of the sky. Many say its not a matter of if, but when. Hopefully you get many hours of flight before that happens. I have had no issues with my P3 but it is only a month old with several flights.  Running FW 1.1.9 (came on the P3...works just fine....dont dare to upgrade!)

With that in mind, here is how I have my bird set up. Just installed chute today. No way to activate it yet as the Mayday board will not be released for a few more weeks but mine is on preorder from northuav.com

Chute deploys from the bottom. It has a 15degree cant away from the landing gear.

In the second picture:
1. Mars Mini Chute from spacecitydrones.com
2. Mars Mini Mount from spacecitydrones.com
3. Trackimo GPS Locater
4. UAV Bits Strong arm plates
5. Gimble Holder

Not Pictured:
1. Gimbal Protector
2. Trackimo Mount (EBay)
3. Mayday Board (on pre-order from northuav.com ships 11/1) See first picture.
4. Small 3v Battery for Mayday Board (keeps it totally automatous in case of P3 power failure!)

My thinking is hopefully if (or more like when) it fails in mid-air, the mayday board will realize what is happening and deploy the chute and hopefully eliminate or severly reduce any damage. And with the trackimo  (which has its limitations as well), I will be able to find it!  Wonder when the day will come that I find out if it all works or not!!!...   

The UAV Bits.....only time will tell if they work.  But cant hurt for the money.

Anyone else have something similar?

Thoughts anyone?

It occurs to me that without stopping the props first, the chute shroud lines would get caught up in the props. From what I read of the Mayday board, it has no knowledge of what is happening to the props.

This is what Kyle from northuav says about how the Mayday board works:


"How could it (Mayday) analyze the flight data to determine if something went wrong if it is not hooked in? "
The Mayday uses its own sensors and IMU to monitor your flight patterns and automatically detect when your quadcopter is crashing. It takes into account falling speed, angular velocity, and other key metrics to make its decision.

This is what Kyle from northuav says about how the Mayday board works:

It may do all that, but if it triggers and the chute pops out while the props are still turning, what is to stop the shroud lines getting wound up in the props? Seems to me the prop would bind up and stop and the chute would be useless.

I'm not sure but I would assume it would require l the motors to stop in order for it to pitch, flip, or decend in a manner to deploy the chute.

I'm sorry, but there is no guarantee that the motors would stop first, could be a bird strike taking out only one prop. The Mayday board most likely contains an accelerometer to work out if the aircraft is wildly pitching and based on that it would deploy the chute. In many cases, the props on a Phantom are still running for some time after it hits the ground, it would be a touch too late then to pop the chute.

Obviously no countermeasure will work in every single situation. In many cases where P3s are falling for no reason, this could save the bird for sure.  It seems as though the product is clearly not for you.....until its too late...lol.

I have not timed my flight time, but havent noticed a loss. Might be losing two or three minutes.  Hasent been enough to notice.  

Learning to fly has not much to do with many of the p3s failing.

Just thinking, I live in Nw England which is very laden with trees. My luck the Chute would grab the first branch on the treetop. Then someone would use my Phantom for target practice.

You are going to have so much in accessories cost that you about could have bought another one in the event of a freak failure.. The thing is going to wear out. Chances are you will have hundreds of flights without issue and that you will be ready to upgrade way before you have any issues. Just quit fretting crashes and go enjoy flying!!! These platforms have proven their ability. ;)

Jim I do agree with you to a point... but I do worry about damaging property or hurting someone if it should fail. I guess i would worry less if I had somewhere convenient to fly  that was not densely populated.

I am all for these kinds of add-ons if they are reasonable and do not degrade performance within reason. I just wish a manufacturer would include a recovery safety system in their products.. It seems to me in the long run it would save them from the bad impression the general public has about these products.

That is so true! A falling rock right? I guess they want to give people a way to make some "after the sale" cash. Or to reduce the cost of the initial investment. Good point!

Awesome reply Butch.  Recovery systems are coming and one day they will be mandatory.  Its all about safety  or the perception of safety.  You can think your bullet proof and that nothing will ever happen with your DJI3P. Thats not thinking, thats wishing.   Its like fire insurance, everyone buys it but very few actually file a claim.  Its not if its coming but when.

Exactly Joe.  That's why I fly with a Flytrex.  I've had two "uncontrolled landings" and a parachute system wouldn't have helped in either one, nor would the Flytrex.  In both the P3 was not damaged other a little dirt and grass stains.  But a parachute system that could be actuated by different factors including a pilot initiated activation would be extremely helpful in many cases.  There have been a number of battery or power failures.

Another thing is that most of these parachute systems are propelled out and away from the aircraft so that the cords clear the props giving time for the chute to open.  Then the drag of the chute will tip the craft over and even with full power the drone will probably just do circles in the sky as it descends.

Hi, i'm digging up an older post by the looks of things. I'm also looking into the Mars Mini and Mayday. I also think that yes unless the P# has good power, it'll fall and the parachute will effectively tip it upside down.

I realise that during the warranty period if you can show a crash was product malfunction you get it replaced, but I'd rather some sort of safe guard.

Anyone else fitted this? More importantly, I wonder if any one has been flying with it for a while and HAD to use it?? or had it misfire and actually being the cause of a crash?

joepilly2 - How are you getting on?

I think a parachute linked to an automatic activation device is fantastic as it might reduce the risk of hurting or even killing somebody if the Phantom falls down. The probability that a skydiver needs his automatic activation device is probably much lower than the probability that a Phantom needs it - but almost every skydiver uses one whereas many Phantom pilots think they don't need it.

But Geebax made a very good point which holds me back from buying such a system. How can such a system guarantee that the parachute will open without the lines being tangled or even cut by spinning props?

"DroPro - But Geebax made a very good point which holds me back from buying such a system. How can such a system guarantee that the parachute will open without the lines being tangled or even cut by spinning props?"

IMHO if the drone is definitely going to crash then I'd rather take the chance of a parachute (which costs a fraction of the price of my drone) being cut and ruined. The logic being that the drone is going to crash either way, but at least with a parachute there is a chance of it being saved. There are only 2 possibilities that a cut  parachute is really a deal breaker to me.

1. The parachute is deployed when it shouldn't have in which case the parachute gets tangled and the drone crashes when it wouldn't have otherwise.
2. The drone is out of control and is going to crash but maybe would otherwise guild it self to the ground somehow and only sustain minor damage, but instead the parachute deploys, get cut and guarantees it falls like a rock. I find this very very unlikely.

My thoughts are that if the drone is out of control enough for the Mayday system to deploy the drone has a near 100% chance of being destroyed anyway, so if the parachute doesn't work. I'm no worse off.

My major concern is if the parachute falsely deploys and causes my drone to crash, which I think would most definitely occur if the rotors are still going and the drone isn't really out of control at all.

If the mayday never falsely deploys I can't see a single negative to having a parachute with mayday except maybe slighty reduced flight time.

I'm interested to hear from anyone who has flown with a mayday since it came out.

The example Geebax made of 1 rotor being taken out is a good example whereby the drone is almost certainly going to crash even though 3 rotors are going. It seems like a parachute with only a 50% chance of saving the drone is better than no parachute.

I received both the Mayday and Mars Mini a couple weeks ago. First thing I found out is that there is no support for the Mac. Can't download the firmware. Very little information on how to test the system, or how everything goes together. No battery, no cable. Yes, there is a video on how to put a dozen screws in. One of the pins is called a signal. I had to ask Kyle what that is for before I could get any idea about it. I think this system is imcompleat and needs some time before it can be used.

anyways. We have available system that weights 104 grams. It includes parachute that stands on landing gear (it doesn't block camera). And what's most important, if triggers with separate remote control (you can call it as "panic button". And it's just a small remote, not bulky giant one ). This way you fully control it (call me old fashioned but i trust myself more). This way you can at least try to power of props while parachute is deploying.  Price is approximately 270$ (+shipping) for parachute system and remote. Ships from Europe. If anyone is interested you can contact me.

Hi Mark,

I`am interested to hear more about your safety sistem. I want to buy for people safety and peace of mind. Drone safety it`s last.

I have some question:
- 104 grams with mounting, mayday and parachute arc?
- are you shure that this sistem does not deploy by mistake?
- this price is including everything: parachute, arc, mayday, remote, mounting sistem?
- how much it`s shipping to Romania?

Thank you Mark.

Hi.
104 grams weights parachute system + 16 grams weights receiver module what you must install on Phantom. So total weight is 120 grams on Phantom.
This system deploys ONLY when you press deploy button on remote (see attachment).Price includes all of this.
Ill find out about price to Romania.

No idea. We are based in EU so you have to find out that by yourself.
If frequency is banned you can use your own transmitter. Parachute system alone costs 125 $

U.S. Public Safety radio bands used by firefighters, police and other emergency radios use 806-824 MHZ and 851-869 MHZ.
So I would consider creating a U.S. transmitter....not everyone is technicolly inclinded as to how to switch transmitters them selves.

It would be good to see a video clip of one of these parachute recovery systems in action. I don't believe that it will work unless the props are stopped before deploying the chute. If you disagree, post a video of it working.
