Review & build log of 180$ HOBBYMATE Comet VX220 Stretch X 5" FPV quad DIY, PNP, BNF - 1800KV (6S) or 2500KV (4S)

I recently tested 145mm DIY KIT from HOBBYMATE and it was fun to build and fun to fly because it flew great and I had zero issues with it so far.

Now I will build and test HOBBYMATE Comet VX220 Stretch X 5" fpv racing drone. Its a high-performance racing drone as manufacturer says.
And from my unboxing experience (pics are in gallery) all parts in the box look high quality. Hobbymate didn't save any money on selection of part for this quad.
And, most of all, all that at most welcomed price of 180$ for DIY KIT.
Comet VX220 comes with airbot F4 V6 flight controller and typhoon 35A (Max 45A), simple connection between the fc and esc is done with a 8pin cable, which saves your time in building and maintenance.
If you don't have time or experience for self building it, you can select prebuilt version in PNP or BNF format.

Comet VX220 fpv drone is a combination of high performance, stability and durability.
Low-deck design means centralized mass and excellent handling.
Stretched-X motor layout is the choice of top racers because the rear props are further from the "dirty air" coming from the front props.
The result is smoother cornering and higher top speed.

  • 5mm full 3k carbon fiber twill
  • High quality 12.9 class Steel counter-sunk screws on the drone
  • Airbot F4 V6 flight controller, tested and proved reliable

Review of VISUO XS812 GPS 5G WiFi FPV w/ 2MP/5MP HD Camera 15mins Flight Time Foldable RC Drone Quadcopter RTF & DVR & APP flight footage

My VISUO XS812 GPS quad just came

and I just did a quick indoor test flight just to check if quad flies and to confirm that camera has no weird jello etc.

VISUO XS812 Quick indoor maiden flight (1 min 49 sec)

Quad flies nice and has no drift, even indoors with no GSP lock, so accelerometer calibration did a nice job.
Remote controls are smooth and also yaw response is nice and smooth.

Review of Runcam 3S WIFI 1080p 60fps WDR 160 Degree FPV Action Camera Detachable Battery for RC Racing Drone & HD flight footage

New FPV session like HD cam from Runcam just came out. Its successor of RC3 (my review of RC3 is here) and its called Runcam 3S. After Gopro stopped Runcam from selling Runcam 3, Runcam did some redesign and lounced RC3S.
It doesn't have waterproof housing or video stabilization, so this is a real HD cam for FPV flyers and not Sports cam like GOpro Hero or Session.
It also has FPV video out so you can use it as a FPV cam parallel to HD recording. Useful for slow flying quads and videography. For FPV racing and freestay flying delay could be issue. I will try to test delay of RC3S.

On full battery it can record for 27min (1080p@60fps).

Video Resolution: 1080p@60fps / 1080p@50fps / 1080p@30fps / 720p@60fps
Video File Format: MOV

details of 1080p@60fps video file:

Image Resolution: 2MP
AV Output Format: NTSC / PAL Switchable
Communication Interface: Micro USB
microSD card supported: 64G max
Battery Capacity: 850mAh

Review & Build Log of Eachine Tyro99 - 99$ DIY KIT - 210mm DIY Version FPV Racing RC Drone F4 OSD 30A BLHeli_S 40CH 600mW VTX 700TVL Cam & DVR flight footage

Its not often that quads come in a DIY kit. This is great hobby and especially part in which you build yourself an quad and on maiden it flies. Its awesome feeling to create something that flies and everybody should try building they own quads at some point.
This is a great opportunity because this kit costs 99$

Its unbelievable price. If you would only by parts by yourself it would certainly cost more.

JHE42B 110DB Finder Buzzer Built-in Battery with LED Light for RC Drone F3 F4 F7 Flight Controller

Notice: Now BG also sells Vifly Finder v1.2 of this battery powered buzzer - lost drone finder- "New V1.2 Version, support 36 Hours beep"

This summer my friend and I were flying over the woods and he crashed. Lipo on his drone got disconnected in crash so he lost possibility to turn on buzzer on his drone . We were looking for his quad for 6 hours and couldn't find it. Loss to be greater, he had GoPros 4 on quad with lots of flight footage. It was lost too.
That evening , when I got home, I ordered immediately this little device. It can work as ordinary buzzer, but slightly louder, but more important it has its own builtin battery so it will sound even flight pack gets disconnected from the quad, plane etc...

I highly recommend this product.

Test jjj (2 min 33 sec)

Review of Jumper T12 OpenTX 16CH Radio Transmitter with JP4-in-1 Multi-protocol RF Module for Frsky JR Flysky

"One transmitter to rule (control) them all"
My new transmitter just came. Its Jumper T12 OpenTX 16CH Radio Transmitter with JP4-in-1 Multi-protocol RF Module.

Transmitter feels nice in hand, and more important sits nice in hand.

Best things on this transmitter are:
  • small, light, compact and east to carry around
  • multiprotocol RF module included
  • JR/FrSky compatible module bay - you can use FrSky R9M or TBS Crossfire modules
  • runs on OpenTX - best transmitter SW available - OpenTX SW runs on very popular FrSky transmitters like Taranis X7, X9, X9D etc... and also possibility to use Companion TX on PC for creating, modifying, backing up and transferring models to other OpenTX running (Taranis) Transmitters

I am looking forward to using it on the longer run, because,
beside using its 4-in-1 Multi-protocol RF Module I am also getting FrSky R9M RF module so I will be trying to fly some long range quad I am building with Jumper T12. It will be interesting I hope.

In my RC pilot life I started with some really cheap 4CH FlySky stuff, than iRangeX iRX-i6X, than moved Turnigy 9XR with FrSky XJT module, than FrSky Taranis X7 and my latest and greatest FrSky Taranis X9D SE.

Now some more info on Jumper T12:
the T12 version does indeed support Crossfire and in CRSF mode with LUA script support
and most importantly WITHOUT any...Continue Reading

I had BAYANGTOYS X21 Brushless Quad, which originally looks like this

with broken transmitter laying around so I decided to get it in the air with parts I had laying around my house.
And now it looks like this:

From X21 I used:
  • 2200mAh 3S lipo
  • frame
  • motors
  • props
  • PDB
  • 5V regulator

I added:
Eachine TX805 5.8G 40CH 25/200/600/800mW FPV VTX
Aomway 5.8GHz FPV 4 Leaf Clover AV Transmission RHCP FPV Antenna
APM Power Module
and orange UHF TX/RX LR system which is now obsolete so I recommend Frsky LR 900MHz system:

and also used for flying this gear:
Taranis X9D Plus Transmitter SPECIAL EDITION
Skyzone FPV goggles
with ImmersionRC SpiroNet 5.8GHz RHCP Antenna
