A smaller and lighter version of the recently released recon 5. in this video i’m going to quickly go over its features and specs point out. The differences between the reckon 4 and the reckon 5 show you how to set it up and check how long and how far it can fly using a 3 000 milliamp hour, 4s lithium battery. First of all, just like the reckon 5. The rakon 4 is available in both analog and digital versions and with multiple ready receiver options. The analog version, which is the one that i’m going to test in this video, is equipped with the codex rotel v2 fb camera and the ajrc zeus, 800 milliwatt vtx and the digital version due to a major cheap shortage, is only available with the cardex nebula nano Digital transmission system, in terms of packaging inside the box, along with the quadcopter, you are getting a single set of jamf and hurricane 4024 by blended propellers. Another set of jam fan floppy property 4019 folding propellers, which i still need to test a small card. That shows you how to install the propellers and actually mine is incorrect, as the recon 4 is using a prop out configuration. In addition, you are also getting some stickers. Two high quality reckon fpv branded battery velcro straps, and the analog version comes with the hdrc hammer. 15 centimeters long rxcp antenna as for mounting an hd camera, you should note that an action camera mount is not included.
So if you’d like to you can purchase one directly from reckon fpv or 3d print it by yourself. As for its packs, the rakon 4 features reckon fpv branded 1404 2800 kv motors, which can handle up to 4s batteries when pushing these 4 inch propellers. It is using the hlrc f728 20 by 20 millimeter stack, which is based on an f7 flight controller and a 28 amperes bles 4 in 1 esc. The analog version features the codex retail 2 micro, sized fpv camera and the agrc zeus vtx, which has a maximum output power of 800 milliwatts and supports our 6 run protocol. The mm6 connector of the vtx is connected to an sma connector, and the connector of the antenna is shrink wrapped for easily attaching it and removing it. From the drone. On the back of the quadcopter mounted inside 3d printed tpu parts, we can find the ajrc m80 gps and a self powered buzzer, which is going to help you to recover the drone in case of a crash. The buzzer is pretty loud and you can hear it from a distance of about 30 meters, each time that you are going to unplug a battery. The buzzer is going to be activated so after about 30 seconds, it is going to sound the alarm and in order to deactivate the batter, you will need to long press this button. For about 2 seconds, an immortal t antenna can be mounted on the front of the drone using an included 3d printed adapter.
It is using an xt30 battery connector. The battery is going to be mounted on the top plate and a plug for powering. A naked gopro camera is pre soldered to the battery pads of the flight controller. As for the frame, its wheelbase is 182 millimeters. It features a wide ax pattern, so the distance between the back motors and the front ones is about 110 millimeters. The distance between the front two motors is about 163 millimeters, and the distance between the back ones is about 140 millimeters. The thickness of each replaceable carbon fiber arm is 3 millimeters and its width is 5.8 millimeters. The thickness of the bottom middle and top plates is 1.4 millimeters. The distance between the middle and top plates is 20.2 millimeters on the bottom plate. You can find 20 by 20 millimeters, m3 and 25.5 by 25.5, millimeters m2 mounting holes for mounting your stack, a cutout for a capacitor and on the back of the frame 20 by 20 millimeters m2 mounting holes for mounting a vtx. In addition, the weight of the reckon 4 without a battery is 168.7 grams, including a gmb 1100 milliampere forest lhv battery and a single battery velcro strap, which is sufficient for securing a small battery. It weighs about 260 grams. In case, you need to stay below 250 grams. The biggest battery that you can use is 650 or maybe even 750, 4s battery, including two battery vehicle straps and a forest three thousand million pr lithium battery.
That will provide you with an extra long flight time. The total weight is 371.3 grams and finally, the total weight of the reckon 4, including a naked gopro 7 black camera and the appropriate mounts is about 204 grams. As for setting up the reckon 4, here, you can see how the post section of bit of flight is configured. The ready receiver is connected to ut1. The gps is connected to uo2. The btx is connected to your tree and in case you have the bla 32 version. The esc sensor is connected to 06.. Under the configuration tab. As you can see, the motor direction is reversed and you need to pay attention to it when installing the propellers. Since my review unit is using a black 224 in one esc, bi directional digital switch is enabled. However, the production version is using a blle s4 in one elc due to the global computer chip shortage. In addition, the maximum arm angle is set out of the box to 180 degrees. Here you can see how the gps is configured by default. The telemetry switch is disabled and i recommend to enable it in case you are using a radio receiver that supports it by enabling expert mode you’ll be able to access the different failsafe options. The gps rescue option is pre selected for you. However, you should pay attention that lr army without fix is enabled as well. So in case you are going to arm directly 4 without a gps fix.
The gps rescue feature is not going to be available. Just as a reminder, i have a separate guard that explains the different bit of light gps rescue feature options and i recommend to check it out in case. You are not familiar with this feature. Next, under the pid tuning tab, we can find the pid red profile and filter settings. The recon 4 is pre tuned for you and in case you change something, and you would like to revert to the original settings. You can check out the dump file, which is included in the description box down below under the receiver tab. You should make sure that all the sticks and switches of your reader controller are working properly after binding it with the ready receiver. You should note that the rsi channel on my version was enabled, and you will need to disable it in case you are using a crossfire or an r9 receiver in order to display properly the rssi on the osd. Here you can see how i configured the flight modes and the osd elements and of course you can adjust them according to your preference and finally, in case you’ve got the analog version. You should pay attention that on my version, the vtx table wasn’t configured properly. So the output power values were incorrect. Of course i reported this issue back to ajrc and hopefully this issue is going to be resolved on the production version. However, i recommend to double check the output power values and in case they are different than the values that i’m currently showing you.
I recommend to use the vtx table which is included down below here. You can see the recon 4 next to the digital version of the reckon 5. Both quadcopters are using the same stack and the analog version of the recon 5 is using the same fov system of the raccoon 4.. So basically, the two main differences between these setups are the motors and frame. The reckon 4 is about 60 grams, lighter than the reckon 5, and, according to my experience, the reckon 4 features a more efficient setup than the reckon 5. So it is going to provide you with a longer flight time and will get you farther when using the same lithium battery. However, the reckon 5 features a more powerful setup, which is very much needed, especially when carrying a full sized action camera overall after testing out the recon 4. I can tell you that, in my opinion, dave c got it right again, as the reckon 4 features. A great combination of performance, agility and long range capabilities using an 1100 milliampere force lsv battery. The reckon 4 is going to provide you with very nice freestyle capabilities, and you can expect between 5 to 10 minutes of flight time. Depending on how you fly using this battery in conjunction with an onboard naked, gopro camera, you can expect between 5 to 8 minutes of flight time. Of course, again, depending on how you fly and in my experience, the acrobatic performance was still great and finally in case you would like to go far and achieve an extra long flight time.
I recommend to use a lithium ion battery pack and using this 3 000 million pr forest lithium battery. I got about 16 and a half minutes of flight time when cruising at an average speed of about 60 kilometers per hour, resulting in covering a total distance of about 17.5 kilometers. One last thing that is worth mentioning before: wrapping up this video with some flight footage. As you may know, dave c is also behind the flywheel explorer which pretty much started. The whole trend of micro, 4 inch long range quadcopters in case you are debating, which version you should get in my opinion. In terms of flight time, the explorer seems to perform better than the reckon 4 and the reckon 4 features more powerful motors. So it is better in terms of acrobatic performance, which is kind of surprising, because both versions are using 1404 motors and there is only 50 kv difference between the motors anyway.
