I didn’t count on a lot from the brand new Flywoo Hex Nano, why would you add two extra motors and ESC when a quad is completely able to doing what we wish? Well, I’m not so certain now, the Nano Hex truly flies higher than I assumed!
Flywoo created the Long Range Hexplorer (Review) just a few months in the past and that was a extremely attention-grabbing concept. They took that concept additional and launched a nano model of it – the Firefly Hex Nano.
It’s completely tiny, at concerning the measurement of a tiny whoop 🙂 Technically it’s a 1.6-inch drone with these 40mm propellers.
How cute is it? It appears comical and ridiculous with that “large” HD digital camera on prime.
INav Version with GPS:
You can even buy prop guards in case you wish to fly indoor.
What I’m reviewing right here is the Betaflight Version with out GPS and prop guards. It comes with the next gadgets:
- Frame: Firefly Hex Nano (90mm Wheelbase)
- FC: Goku HEX F4 (16×16)
- ESC: Goku Hex 13A 6in1 (16×16)
- Motors: Flywoo Robo 1202.5 5500KV
- Propellers: HQ 40mm 4-Blade Props
- FPV Camera: Caddx Ant Nano
- VTX: Goku VTX625 450mw
- Antenna: RHCP Atomic 5.8GHz Antenna (30mm lengthy)
- Supports 4S LiPo Battery
- Weight with out LiPo: 66g
- Weight together with Naked GoPro and a 4S 450mAh LiPo: 146g
The Hex Nano seems to be nicely designed, all of the parts match properly contained in the body.
The cable that stands proud is the facility cable for the SMO 4K camera, it’s pre-soldered to the FC out of the field. The Hex Nano comes with two 3D printed TPU mounts for the SMO 4K digital camera, and the Insta360 GO.
I “modified” the TPU mount to suit the Naked GoPro, it’s not preferrred, but it surely works for now.
The 3D printed antenna holder works nicely for holding the antennas securely in place. The general design and construct high quality are wonderful.
The motors are 1202.5 5500KV, paired with HQ Micro Props (40mm 4-blade 1.5mm gap) that are normally utilized in Tiny Whoops. Yes you heard me proper, this 4S hexacopter is utilizing tiny whoop props, loopy proper? 😀
The F4 FC, ESC and VTX stack is designed particularly for this Hex Nano.
Here’s the pinout / wiring diagram:
I like these fading RGB LED lights coming from the ESC and FC. They are fairly vibrant, and aid you spot the drone from far-off. You can disable them in Betaflight LED tab if you’d like.
Repairing must be straightforward, there are solely 3 screws to take away and the highest plate pops proper off.
Now, onto the issues that may be achieved higher.
The backside plate (arms) is sort of skinny (1.5mm thickness), it truly flexes whenever you press on the arms. Note that it’s a uni-body design, which suggests for those who break one arm, you’d have to switch the entire backside plate.
Hexacopter is cool, however transferring 6 motors throughout to a distinct body is 50% extra work than a quadcopter. I want Flywoo may use thinker carbon fibre sooner or later, not solely it’s extra sturdy, however a stiffer body is definitely higher for flight efficiency.
The FPV digital camera sticks outdoors of the digital camera cage, it will have been safer in the event that they made the TPU mount a bit longer to offer extra safety. Camera tilt angle is round 15° to 90°.
I’m not an enormous fan of the battery strap, however I suppose it’s a approach to save weight, and it does work to start with, but it surely slowly loses stickiness. On prime of that, the battery pad can also be a bit slippery, and the battery can slide out of the strap sometimes. It would have been good if sticky and thicker pad was used.
Finally, I’m not certain if the Firefly Hex Nano will make a dependable lengthy vary drone as a result of the antennas might be fully blocked by the HD digital camera within the entrance when the drone is flying in the direction of the pilots.
But for brief vary (inside 500m), the Hex Nano has been performing completely nice for me signal-wise. However I used to be getting a bit extra breakup within the video than fashions that use longer unobstructed antennas.
Together with the truth that there’s no buzzer onboard, I might keep away from flying too far-off to keep away from dropping it in excessive grass, it will be difficult to search out it, particularly it’s so tiny 🙂
The dealing with of the Hex Nano positively feels totally different from a quad, however by way of energy and agility it’s fairly just like a 3″ toothpick (with out the additional weight of the HD digital camera).
Out of the field, it’s very steady and locked in cruising flights even when it’s breezy. Flywoo did a wonderful job tuning this quad!
Mind you it’s not tremendous highly effective due to the small 40mm propellers, however freestyle and acro strikes are completely doable and looks like a bigger 3″ ultralight quad.
However, in sharp turns, it loses extra altitude than a quad, and you may really feel it carries a bit extra momentum too as a result of it’s heavier, and people tiny props are simply not producing an enormous quantity of thrust.
Although it has two extra motors than a quad, it’s truly not as noisy as I anticipated. Again, corresponding to a 3″ toothpick, and it’s positively extra stealthy than a 2.5″ cinewhoop like the 95X V3.
With 4S 450mAh, I get about 5 minutes of flight time simply cruising (with out the HD digital camera), and if I push it actually onerous, it’s about 4 minutes. When carrying one thing like a Naked GoPro on prime, flight time is lowered by about half a minute, but it surely’s nonetheless fairly spectacular.
I used to be getting some interference in my FPV video (black bars) as you may see in my flight footage. It’s a little bit distracting however not the tip of the world.
Get some spare props, you will want them as a result of they’re simply “pushed in” and might break or fly away in a tough crash: https://oscarliang.com/product-u2ui
It is advisable to make use of 4S 300mah (4min) or 450mah (5min) batteries: Best 4S LiPo Battery for Whoop and Micro Quad (300mah-650mAh).
Setting up was barely complicated, I hope they repair it within the manufacturing model.
Basically, they designed this quad with GPS in thoughts. I suppose they later determined to not do it on the Betaflight model, however left GPS enabled on UART2 within the Ports tab and forgot to vary it? So as an alternative of placing SmartAudio on UART2, they put it on Soft Serial, which additionally works, however a complicated configuration for freshmen.
GPS characteristic was enabled within the Configuration tab – you possibly can disable it to avoid wasting CPU load.
Make certain to verify Failsafe is ready to “Drop”, and never set to “GPS Rescue”, simply in case it gained’t do something sudden within the occasion of failsafe.
OSD additionally had all of the GPS stuff turned on, which we gained’t use. The FPV digital camera is NTSC so be sure that to place OSD parts within the right portion of the display in order that they don’t get chopped off.
Apart from that little setback, the remainder of the setup is easy and straight ahead.
- Bind the Crossfire Nano
- Turn off Motor_Stop within the configuration tab (air mode is enabled anyway, I don’t perceive what they enabled Motor Stop for)
- Turn on ESC Beacon because it doesn’t have a Buzzer, it’s higher than nothing
- Change charges
- Setup switches for Arming, Beeper and Turtle mode within the Modes tab
VTX was in “locked mode” out of the field, that means among the channels are inaccessible with a view to adjust to rules. And if you choose these channels it’ll simply put you on one other random channel. For instance, on Raceband solely R4, R5 and R6 can be found.
To unlock the VTX, merely maintain down the button on the VTX for 10 seconds. Fortunately the button is well accessible with out a lot effort.
While everybody within the FPV trade is actually simply copying one another, I’m glad Flywoo is making one thing that’s really distinctive and attention-grabbing. And it truly performs nicely and deserves our consideration!
Because it’s a hexacopter, it’s gonna be costlier than a quad with the 2 additional motors and ESC. It additionally takes two extra props so in the long term it’s going to price extra. But it offers you respectable flight efficiency in such a small kind issue, it’s a reasonably thrilling new idea and concept!
There’s no DJI model but, solely analog for now. But it’s lighter anyway. I do hope they launch one thing that makes use of the Naked Vista sooner or later. 🙂
You can get the Flywoo Nano Hex right here (Betaflight Version):
As I discussed within the overview, the antennas aren’t optimally positioned on this quad… I imply hex, it’s not precisely the sort of drone I’d use for lengthy vary. But Flywoo determined to launch an iNav model with GPS module on prime. I suppose it will be cool to have options like return to dwelling and altitude maintain. I’d test it out when it’s obtainable.
