Eachine Tyro79 Ultimate Final upgrade guide

The Eachine Tyro79 is a low cost brushless high performance FPV quadcopter that is sold sold as a kit exclusively from Banggood. I have written a full review here and the popularity has prompted me to write this full and final upgrade guide after nearly a year of testing, tweaking and changing parts. Sadly my Tyro 79 has been lost in a dense bush area and I have not been able to recover so cannot share pictures of the upgraded on the quad. However, I have noted carefully what has worked for me and this is shared below split into the following systems:

• FPV (camera, vtx, vtx antennas, goggles)
• Motors and props
• Electronics (flight controller, ESC)
• Frame
• Batteries
• Control gear (receiver and transmitter)
• Add ons
• Betaflight

I'll make my strongest recommendations clear in each section and will recap in the summary as well.

FPV systems (Came, VTX, Antennas, Goggles)
I put this first as I think the most crucial improvements are here. Without mincing words the default camera is awful. Although it was working well for the first one or two flights you can see from this video below in slightly overcast conditions that it can be nearly impossible to fly.

The good news is that the tyro79 takes a standard micro 19mm camera and there are some good options available for not much money as below. This is the very first upgrade I would recommend.

Foxxer Arrow Pro Micro. Still my favourite bang for buck micro camera at less than $20 with a CCD sensor.

Caddx Ratel Micro. This CMOS cam has a massive sensor and excellent performance as a result. Can be had for as little as $25 on sale.

Foxeer Razer. The new budget cam from Foxeer with a CMOS sensor. Personally I prefer the Arrow but this is an option if you prefer CMOS

I had no issues with the VTX personally but have seen several people who have online. The 20x20mm VTX that the tyro79 uses is very common and there are some excellent options available. My three recommendations are below as your budget allows but all three offer smar audio control and a minimum of 200mW maximum power which is plenty for this quad. All require soldering and/or splicing of wires. With that said I used the stock VTX right up until the end. If you do want the stock vtx it can be found here but I'd honestly recommend one of the below ones in its place.

AKK FX3 Ultimate VTX. Probably the best stackable direct replacement and is less than $20. Has both UFL and MMCX connectors. My review here.

AKK race vtx. Best budget option at less than $10 but youll need to convert antenna to MMCX and you are limited to 25/200mw - which is just fine IMO

NamelessRC Nano400 VTX. If you want to go light this is your best option. up to 400mw and less than 1g for about $15.

The Tyro 79 uses a basic dipole antenna connect to the VTX by mirco UFL - another common standard. These are perfect fine when flying by yourself and as durable as it gets. I would recommend a MenaceRC Bandicoot Linear Patch Antenna if your goggles have diversity though for increased range. If you are flying with others though yoy will want a circularly polarised antenna. These three below are compact, reliable and connect directly to your VTX.

Foxeer Lollipop 3 is a good performing durable omnidirectional antenna that will connect direct to your VTX. Pack of 2 for $20 or less

If you are flying alone the stock dipole is fine but would strongly recommend a Bandicoot linear patch on your goggles for improved range

The Axii is the Rolls royce of micro antennas and are $20 each. Probably a bit of an overkill but here if you want.

Budget plays a hug part on choosing goggles if you haven't done so already. I'm wary to recommend spending too much at the moment such is the impact of the HD DJI systems but bang for buck in any category is the Aomway commander V1s which is being cleared at less than $200. My full review of that goggle is here. Other goggles I can recommend are the Fatshark OLED Attitude V5 (review here) and of course the skyzone SKY03O OLED goggles (review here).

Motors and Props
If the camera is the first thing you should change, the props are most definitely the second and regardless, they are a consumable item anyway. The stock 4-blades are awful - loud, inefficient and full of vibrations. Prop choice can vary depending on flying style but the below options are all very durable, efficient and reliable

Gemfan Flash 3052 One of the earliest prop I used and still one of my favourites. The aggressive pitch works well with the Tyro79 motors

Dalprop t3056c Very similar in performance to the 3052 but a little more durable

HQprop 3x4x3. A little less pitch but very quiet and efficient.

The stock motors are heavy, have bearings that are prone to premature wear and have awful plastic coated wires but they fly fine. If you damage or want to upgrade I'd recommend the options below. They are all physically smaller and lighter than the stock ones but make more power and are more durable

HGLRC FLame 1407 3600kv. These are fast and light motors at a budget price. Perhaps not as durable as the 2 to the right but much better than stock and only $10-12 each

RCInpower 1506. This motor is beautifully made and amazing to look at. Power is a level up with wider stator. 4300kv will be very fast on 4s but also power hungry. I reviewed similar here

BrotherHobby Tornado 1407 3600kv. The original hot motors for 3 inch 4s quads still hold up well today. Try to get them on special for about $12 each.

Electronics (Flight controller and ESC)
This is pretty much a case of "if it's working it's fine". If you do have issues I only have one recommendation which is just so much better value than anything else around:

Diatone Mamba F405 Mini FC and ESC. At around $40 for the stack I simply cannot recommend better for the price. You don't even need a BLHeli32 ESC because with JESC you can get 48k PWM and bidirectional d-shot.

Frame
I'd only recommend replacing the stock frame if it gets damaged. Given this is a 1-piece bottom plate this is a distinct possibility and I'd recommend the following option as a replacement. Not, some trimming of wires may be required with these frames but the components will fit.

Diatone GTR349 frame and canopy. Well build nice light frame and canopy kit for around $25

Flyfox no 5. About the same weight as the diatone frame but with a full carbon canopy

Ummagawd Acrobrat Duo Probably the best acro 3 inch frame going but spendy @ $45

Batteries
4s is the number of cells you will want for the tyro79 even if starting since maximum throttle can ealiy be limited if needed (see article here). Capacity will be a matter of preference though. I'd recommend 650-850mah in general - smaller than 650mah won't be able to supply enough current at full throttle and larger than 850 will start making it feel heavy and sluggish. I personally run CNHL ministar 4s 650mah but here are a few options:

GNB 4s 650mah

GNB 4s 850mah

CNHL Ministar 4s 650mah

CNHL Ministar 4s 850mah

Control gear (Receiver and Transmitter)
I run FRSKY gear and will look at only these options for the purpose of this review. I feel it is a good price/performance ratio but of course there are cheaper and more expensive options. For receivers:

FRSKY XM+ Great little receiver that allows you over 1km range with diversity for around $12. I use these by the truckload.

FRSKY R-XSR As light as the XM but with diversity of the XM+. It also has full telemmetry and is updatable to the latest Fport and ACCESS standards. $25 is spendy though.

FRSKY XM About $1-2 cheaper and 1g lighter than the XM+ but without the diversity. I'd recommend the XM+ instead.

Things are getting a little more tricky with transmitters now that FRSKY is going with the closed source ACCESS protocol and my choices below reflect this:

FRSKY X-Lite (original ACCST). This is my long term favourite transmitter that runs all the current receivers (review here). Crossfire works using the adaptor in this article.

Jumper T16 Pro Hall. If I was to buy a new transmitter today this would probably be it. Compatible with practically every receiver and support crossfire natively.

FRSKY X9-Lite pro. New small form factor with click wheel. This does not support the old D8 protocol but does support the new ACCESS protocol. This one has the hall effect gimbals

Add Ons
Probably the first add on you might consider is an HD cam. The Tyro79 can carry a stand-alone HD cam, particularly some of the lighter ones but performance does take a bit of a hit. Alternatively you can replace your FPV cam with one of the split options - a camera and board that transmits in regular analogue but can record in HD

Runcam 5 HD 4k cam

Best image of the lot but even at a relatively light 56g it is a lot for the Tyro79 to haul. Full review here

Hawkeye Firefly 2

Much more suitable weight at 31g but a definite hit on video and audio quality. full review here

Runcam Split 3 Mini

One of the more recent and reliable split options at 1080p for around $65. This replaces the FPV cam as well

Caddx Tarsier

​A more expensive split option but offers up to 4k resolution for $85. Also a good FPV cam.

The other item you my want to consider is GPS because it is simply a lot of fun. You get true speed readings, accurate location details if your quad goes down and you can enable the return to home feature on betaflight. GPS modules are only around $10 and are easily set up. I'd recommend the Beitian BN-180 - it is small, cheap, light and of the 3 I've had - reliable.

Betaflight flight software
Betaflight is the free flight firmware that comes installed on the flight controller. By upgrading to 4.1.1 or above will see a big improvement as the stock tune is now excellent. You can go one step further and install JESC on the 4 in 1 ESC for around $5. This will allow you to run 48k frequency on your motors which add smoothness and extend flight time but more importantly this firmware adds bi-directional dshot meaning you can run RPM filtering that everyone is talking about. This seems to be the single biggest improvement to tuning I have seen in my time in the hobby. Sadly I did not get to write my guide for RPM filtering on the Tyro79 before I lost it but install is straightforward and there are a lot of guides out there.

Summary
Well that wraps up my Tyro79 upgrade guide. More detail above of course but the very first things I upgraded were props and camera because the stock items were miserable. VTX was fine as was ESC and FC but there are good budget options to replace these line the diatone mamba stack and the vtxs above. Upgrading motors will give you a good performance bump but I'd stick with the stock ones until they die. Having a number of good batteries is key, you'll need these regardless but definitely go for 4s. Radio gear is farily personal but I still like FRSKY because it is a reliable link and receivers are small and inexpensive. Adding an HD cam is a good way to capture you flight in high definition. If you have the energy, go for one of the split cam options because hauling a stand alone HD camera can tax performance.
