AKK FX2-R 5.8Ghz FPV VTX 25mW/200mW/500mW/800mW with MMCX to RP-SMA Support OSD Configuring via Betaflight Flight Control Board

Excellent VTX if powered off a external 3 amp adjustable style buck regulator.. run at 9 volts of the reg and the 3 amps will power this and the cam no issues at all and will give you flawless video without needing caps. It's a little more wiring but a adjustable 3 amp buck is tiny and easily mounted in all but the tightest builds. If you power off the battery leads and don't have a main lead cap on place you will have serious video noise, if you power off a on board 12v reg and run over 200mw you will pull to much current off the FC board and cause heat issues or brown outs/restarts. This VTX, puts out very consistent output powers to what it's rated at, on my Very accurate 2nd Gen IRC power meter it puts out about 23.8 to 24.6 MW depending on temp, on 200 it puts out about 195 to 210mw, at 600mw it puts out about 610 to 620 and at 800mw it puts out about 860mw and that's a avg of 6 units I have (I'm a Unify Race guy on all my race builds, and run the normal Unify on most of my practice race builds and most my freestyle builds as it's the best vtx imho but it's also more then twice the price as these) I use 2 of these on long range flying wings, 2 on 5.5 inch quads and two on 5 inch quads one a practice race build and on a freestyle build. I run them all as I stated off a 3 amp reg set to 9v.. the two wings are running Runcam Eagle Pro 2s, the 2 5.5 inch quads are running Eagle pro Micros, the two 5 inch are running Caddx S1 Micros. Running them off the regulator gives me absolutely perfect video with no extra filtering needed. The buck plus wire weighs about 3 grams and is smaller then the Crossfire Nano receivers I run.On the two wings one being a 41 inch carbon monocoque monster (ready to fly weight minus battery is only 194 grams, and shes totally slippery in the air due to the moulded carbonfiber that gives me the perfect shape and is totally stiff and a knife edge leading and trailing edge this plane is super efficient in the air) running a Tmotor F40 Pro v2 2150kv on two Tattu R-line 6s 1800mah packs in parallel, for a 6s 3600mah pack turning a GF5152x2 prop and two 10 gram Futaba Digital servos S3776SB S.Bus 2 super high preformance micro servos a Full sized Crossfire RX controlled with my MZ32 Pro running a full Crossfire module, Airbot Firework V2 with Inav as a serial pass through, I do not fly it in anything other then a control pass through so it just acts like a receiver with no flight assistance.. it's so I can use a serial single line rx and have a full osd and I use a Airbot Wraith 80 amp metal fet esc so I have super esc reliability.Why I explain this specific build is so I can give you the preformance of this setup running a laforge with a flat panel/patch directional antenna and a Triumph omni clover leaf antenna on my HD3s or HDOs (i normally fly planes,only with my HD3s as I like,the FOV setup on the HD3s for plane flying over the HDOs.) This plane will cruise at about 85mph only pulling about 9.5 amps wot will push me about 125mph level flight but pulling over 47 amps constant once it's fully accelerated and close to 60 amps If I'm cruising about 30% throttle and 40mph and nail it it will pull about 60 amps and taper down to 46 to 47 amps.. but where it's utterly impressive is at about 75mph level flight at 63 to 65mph will be plying pulling about 4.0 to 4.3 amps on a 3600mah pack I have some duration. Now with the video setup I told you about and a Triumph antenna on the wing mounted on 5 gram servo powered hinge that will move the antenna from 90 degrees straight up off the winglet to to 90 degrees straight down and anywhere in between. It allows me to position the antenna facing downwards in flight so as to always have direct LOS to the antenna and the back to up for landing. On 800mw that's really putting out about 860mw I have been out 7.5 miles on this setup with flawless video.. I could go further but I would only feel safe going out much further then that with a proper ground station and antenna tracker and a properly tuned cross hair or a high Dbi helical antenna. But with such a simple antenna setup and a true 800+MW of power 7.5 miles was a cake walk, there's dvr of the flight on YT and the video to my eyes as always was better then the DVR but as you will see i have hardly any break up and crisp video and flew around in all directions when I reached 7.5 miles for about 15 mins before heading back and have wonderful video quality... so good in fact I was comfortable take a 7.5 mile out flight with no auto pilot (IE: no return to home, I knew my Crossfire would have not the slightest issue at that range but video was a concern but it was so good I didn't think twice about doing the flight a second time, the 2nd flight is the one posted up) I had the Crossfire pushing out the full 2000mw/2watts at 2watts I've flew a long duration twin motor plane carry 32000mah with of 6s power and been out over the water to 83 miles out and RSSI never fell below 92% and was 94 to 96% the whole flight with a flight plan of 330 feet off the water. But the video on this transmitter at that range is amazingly good there's hardly any channel bleed about as good as the unify on that and that's very good in fact the best at not bleeding to other channels.. the power is consistent and so long as it's got some airflow to stay cool it will put out the power asked of it with no issues and it doesn't drop over the flight from heat as a lot do. I have yet to have one fail, even on one of the 5.5 inch quads that had a crash and pulled the mmcx dipole out and it took me about 10 mins to get to and unplug the quad it was transmitting at 600mw and without a antenna for over 10 minutes and didn't burn out, I tested power output after and it was exactly the same as before and the vtx was scalding HOT when I recovered it prolly close to 200 degrees F and it hurt it in no way shape or form.If you are looking for a 30x30 stack mountable vtx this is imho the best choice, not just for the money but period. I fly the Unifys because I know them well (and get them at cost from a retailer I'm sponsored by) and most my race setups won't allow a 3 stack, they clear a 4 in 1 esc and a FC with room for a Crossfire Nano and a Unify Race taped to the top deck side by side and that's all the room I have. On builds that I have room (freestyle builds and planes) for this unit in the stank i will be using these a lot. I just got a hold of 5 of the 1.8 watt AKK units form a retailer that i work with that had to stop selling due to FAA regs so they had 5 left and gave them to me. I have some really cool ideas for them.With a proper antenna setup and if you know what your doing 10 miles on the normal 800mw unit is easily doable without a antenna tracker or any specialised ground units. I will do a ten mile out flight soon and post it just to show how good a true 800mw vtx and a quality omni antenna and a good patch antenna is capable of. Honestly 10 miles is safe if you know what your doing and make sure that you have solid LOS to the antenna the whole time and keep your antenna pointed in close to the center of the signal width of your patch antenna and you can really get out there without a antenna tracker on 5.8 with clean video that it totally reliable. I will say that I the wing I was talking about has now been setup with a high quality neo 8 GPS and perfectly tuned in Inav and setup for multi flight modes and RTH failsafe. I've also changed the power setup slightly running now a 5s 5000mah pack that is the same weight as the 6s 3600 and I have the same preformance except on top end and I never use that anyways and my 60 to 70mph amp draw is only .5 to .6 of a amp higher so I have about 23% more flight time at that cruise speed of 65 to 67mph and the plane will still daily break 100mph level flight if I want it to.I will soon post a 10 to 12 mile out flight for all to see and I have no no doubt the video setup will preformance safely at that range but I will do over flat land with no one and no property even close for safety sake. If all is good at 10 to 12 i will then do a 20 mile out flight with simple antennas but will use a antenna tracker on that flight and I believe it will do it with the right setup, 20 miles out would be all I could do safely on the power setup I have and going beyond that would just be silly for a 41 inch wing.

This VTX is a bit bulky can't really tell the difference between 200mW and 800mW.

I didn't like the choice of antenna pigtails. It forced me to look for a another version but it seems that us the standard. I have to use a RP SMA adapter to attach my antenna. I will get the proper antennas in another online purchase. I have the adapter but I had to borrow it from another system. Now I can power it up and see how it works.

Fried it first day. Wired correctly working fine then poof!

I know nothing about how this VTX acts with other pilots around because I know no other pilots in my area to fly with. I do know that I can get almost a mile out with my freestyle quad and this thing doesn't care. Great transmission either way. And I like that I can mount it in the stack.

This VTX is like the quality of a $50 VTX I highly recommend this product!

This VTx is very compatible with flight controllers of the same dimension, and the hardware it came with made it very easy to install on my multi rotor.

Fit to drone
