EVO II Payload Drop System (Navigation or Landing Light Activated)

You have to do a little modification of the drop system, but when done it is activated by turning on the forward navigation light (or landing light) in the Explorer app.

I too modified a DROP SYSTEM MADE FOR DJI. I cut it in half and reoriented the two pieces of the drop system. It's a light activated servo release mechanism. The reoriented pieces, now glued together sit on the top of the drone and the servo release bar is against the middle side of the drone. The light activation sensor is attached to the landing light. I used 10 lb rated velcro to attach the system to the top of the drone. The wire for the light runs down the opposite side of the drone and sticks to velcro placed on either side of the landing
Hi there quick question you said you used landing light where do I need to solder my wires to? I take a light our and use that
 
I made a universal drop system, that just velcrose to the top of any drone. It is L shaped. The main mechanics ar velcroed to the top of the drone, while the release pin runs down the side of the drone. The benefit of the pin running down the side, is that any object you hang from it doesn't interfere with the ground sensors. The light sensor runs down the side of the drone to the landing light. I used hot melt glue to fix it in place, so I could remove the sensor and glue later. You can use velcro if you want a temporary light sensor attachment to be able to remove the whole thing at your whim. Here are some pics. It fits my EVO 2 as well. But I converted this Mavic 2 zoom into a fishing drone only. That's why I used a more permanent fixative (even though it can be removed) for the sensor to the landing light.

Question if you don't mind so I need to take out one of the lights and then solder my wire where?
My drop system mod does not require any modification to the drone (Do not modify your drone). The drop system has its own power supply, the only modification I made was to the mounting clip for the Photoresistor that activates the release servo.

He is using the landing light (other use the arm lights) to activate the photo sensor that comes as part of the drop mechanism. It's on a wire so you can attach it to any lights on the drone that you can turn on and off. You simply put the photosensor over the landing light or arm light, making sure no light get's in from the sides. You can use velcro, a strap of some kind or whatever the other poster used to keep the photosensor over the landing light or the drones arm light. It's a photosensor from the drop mechanism that activates the drop, not a wiring job.

Evo II payload drop system using a system designed for the Dji M2. Only changes are for the sensor that mounts to the navigation light.

Got tired of waiting for a payload drop mechanism that didn't need to be modified to function on the EVO II. This system works perfectly without any modifications to the release mechanism. You will need to modify the mount for the sensor that is triggered by the navigation light.

With a 1" piece of 1"id sch 40 pvc, a Dremel, 3" of small wire to extend the lead for the sensor and about 1hr your done.

Drop system

The system does not sit lower than the bottom of my Dual camera.

I know it is not a out of the box solution, but finding a drop system that does not have to be modified to fit on the airframe, does not interfere with sensors or ground clearance is nice.
It would really be great if you could make a video showing exactly how to make the payload release functional for less tech savvy people like myself

No video needed.

The payload release system fits the Evo 2 fuselage perfectly and needs no modification so the only thing you need to do is put the photoresistor over a controllable light source (navigation light or landing light).

The easiest way would be to disassemble the supplied navigation light clip on mount (carefully) so you are left with only the wired photoresistor and then mount it over one of the landing lights.

Note:
This drop system is only rated to 1lb

Is this the correct payload system to use ?

Thanks for reassuring me I had the wrong one I couldn’t find that one on Amazon prime but I found it thanks a lot
 
No, the one I used is for a Mavic 2 not Mavic Air.

Ok so good news I just got the correct release from Amazon and I’m putting it together now. So does the release mechanism work from the remote ?

Depends on which light you mount the Photoresistor on. Front navigation or landing light, They turn on and off in the Explorer app.
 
Also what is the photoresistor?
It is the light sensor that goes over the navigation light in the system you just bought. You need to take the one out of the clip (carefully making sure the wire connection stays intact) and then make your own system to attach it to the light source of choice.
 
Dude I’m so confused I’ll literally pay you to make a video of exactly what to do. I know what the navigation & landing light is but I’m not sure about the light sensor. Is it the white cord that plugs into the release ?
 
Yes the sensor is in the plastic piece at the end of the white wire (see attached picture). You need to take apart the plastic clip (circled in green) be careful not to disconnect the sensor from the wire.

How do I connect it to my evo 2
