What Is Tiny Whoop?

Tiny Whoop is a small FPV micro brushed quadcopter, its propellers are protected by EDF ducts that also makes it a very efficient little machine, we can fly FPV around people and kids safely. It allows some insane indoor FPV flying: chasing people, annoying your pets, cruise around the house without hurting anyone or damage anything. Compared to mini quads, the tiny size opens the horizon for new possibilities in FPV hobby. It’s more fun than I’ve ever had.

What are their advantages?

  • Tiny size, making them ideal for flying indoors, through shelves, under desks, wherever.
  • They are Efficient, with up to 4 minutes of flight from a tiny battery.
  • Acrobatic Performance, capable of flips, rolls and fast climbs due to their power to weight.
  • Robust, their ducted design also allows them to shrug off most wall impacts.
  • Inexpensive to purchase and repair. Even the bigger-budget bundles represent great value.
  • Many on the market are ready to fly, and such accessibility is rare when it comes to FPV.
  • They are just awesome fun, seriously even if you just want to fly and not tinker.

What do we need know when we build a Tiny whoop?
You can choose to go full-blown with 2S motors and batteries, or even opt for brushless motors (more on this another time!).
A typical build will contain the following parts:
  • A frame (80-100mm should be good)
  • A flight controller (the SPRacing F3 Brushed is a great choice)
  • Motors (8.5mm brushed) & propellers
  • Battery (400-750mAh; 1S/2S)
  • Receiver (depends on what transmitter you have)
  • AIO (all-in-one) camera (the FX798T is a proven champ)
You can read our Quadcopter frame, lipo battery, motor and propeller size matching table to know more about how to build quadcopter.
Batteries
Tiny Whoop use 1S 150-205mah LiPo batteries and flight time is about 1-2 minutes. Between different brands and discharge rates there might be a difference in flight time. It’s best to get loads of them. I think 10 to 15 of them is a good number to for a living room FPV racing session.
Motors
There are two types of upgrade 0615 motors sold by micro-motor-warehouse: medium & fast. Type of upgrade motors has an impact on performance and battery life. Because stock PIDs on the Inductrix main board are not adjusted to fly with neither medium nor fast so when flying in acro mode motors sound like they struggle and also there are some oscillations. I didn’t have a chance to test the stock motors with FPV gear on so can’t confirm how they perform in acro.

FPV Lipo Review: Tattu 1300mAh 4s 95c Lipo battery

Now most drones are all using Lipo battery, without the Li-Po technology drones could have not evolve this fast. Biggest advantage of lithium polymer (LiPo) batteries is that they have about four times the energy density of the nickel cadmium or nickel-metal hybrid batteries.



Tattu R-line 95C, 4S Li-Po battery review

Disclosure: I received this battery as part of a product review collaboration with Gens Tattu. Although the batteries were offered for free, all opinions in this article remain my own and I was in no way influenced by the partner.

Although I requested only one R-line 95C 4s Li-Po, I received 3 pieces. Nice surprise, thanks again. Batteries were well packed in a huge box. Each battery comes with its own safety instructions and charging plug protector.

Battery measures around 36 x 72 x 32 mm (W, L , H) and weights 163 grams. Due to thick discharge cable and aluminium envelope, the Tattu R-Line weights about 10 grams more than other 4s Li-Po batteries with same capacity. As you can see in the image bellow it has similar size and form factor with the Walkera F210’s stock battery (1300mAh 4S lipo).


Tattu R-line 4s 1300 mAh battery technical specs
  • Higher capacity than comparable size packs;
  • Designed for professional drone FPV racing;
  • No memory effect;
  • Minimum of 1300 mAh storage capacity;
  • 4 cells of 3.7v. Total voltage of 14.8V;
  • Total power of 19.24 Wh;
  • Ultra high discharge rate of 123 A (95C);
  • Maximum burst discharge rate of 190C;
  • JST-XH charging plug;
  • XT60 discharge (drone) plug;
  • Net Weight: 172.6 grams (±20g);
  • Dimensions: 72 x 36 x 32 mm (L W H).
Charging wires are 22AWG, which according to Wikipedia can handle up to 7 Amps. Note: Tattu allows to charger their R-Line 4s 1300mAh battery with max 5C, 5 x 1.3 = 6.5 Amps.
I received all the batteries about half charged (47%). I measured 15.34V on the XT60 plug. Cell 1 – 3.84V, Cell 2 – 3.84V, Cell 3 – 3.82V and Cell 4 – 3.84V. BTW, 3.8 V/cell is the voltage recommended for storing Li-Po batteries.
Tattu R-line 4s 1300 mAh review: Test
Being a responsible guy (and also afraid of explosions), before any test I read the instruction guide. I know that Li-Po batteries require special handling but it was shocking to read that I need to use a fireproof cement concrete bunker to store the battery : -S.
After I discharged the Tattu R-line 4s 1300 mAh to about 10% I started to charge it with 0.7A using my SkyRC iMAX B6 Mini charger. The charging process stopped after about 2 hours, when battery level reached 16.81V (4.2V / cell). The Li-Po battery did not heat up at all and the stored capacity was of 1258 mAh. Second day I went out with my Eachine Racer 250 Pro and  Walkera F210 racing drone in order to do some punch tests.
The Tattu R-Line 4s 1300mAh battery performed very well, punch-outs are even more impressive than with stock battery. I could say that also flight time was better, but this could be hardly determined because every flight is different. Full throttle drains the LiPo battery much faster than just hovering.
Trying few flips I had some crashes too. Battery remained intact and safe for further use.
Summary
As I didn’t have fancy gears to measure the exact spec of the battery, I can’t confirm that the R-Line truly delivers 95C but, in my opinion, if it has only 75C is still far enough for most of the racing drones.
I liked that the battery was carefully packed and it came with detailed safety instruction (En, DE and CH).
Because lately ordering Li-Po batteries from China became more and more difficult, is good to know that now you can order it directly from Gens Ace Europe or US warehouse.
Pros
  • Available to order directly from EU (Germany) and US warehouse;
  • 95C, ultra high discharge rate;
  • Well packed, with included plug protector;
  • Aluminium envelope for good heat dissipation and some crash protection.
Cons
  • Heavier than similar batteries.

Parrot Mambo Mini Drone

The Parrot Mambo is a mini FPV drone with cannon and interchangeable grabber. It’s small enough to fit in the palm of your hand, and come with lightweight, making it perfectly suitable to flight indoors. It supports modular accessories and it’s those accessories that set this latest Mambo apart from similar drones. It’s a small plastic drone that’s intuitive to fly and lots of fun. It can be flown using your smart phone.
Features
  • Indoor and outdoor minidrone
  • Grabber and cannon accessories
  • Bluetooth control from a smartphone (controller optional)
  • 30 minute charge time for 9 minutes flight
  • 5m/sec maximum speed
  • 3-megapixel camera / 1GB internal storage (not expandable)
  • Weight: 63 g (without bumpers or accessories)
  • Dimension: 71 x 71 x 18 mm
  • 60 FPS vertical camera; Streaming and Recording HD 720p 30 FPS FOV 120°
  • 660 mAh Lipo battery
 Performance
It has never been so easy to escape thanks to the Parrot Flypad which lets you fly your Parrot Mambo over a distance of up to 100 m. Fly not only farther, but also longer with the new high-performance Power Battery lasting up to 10 minutes. There are 3-axis gyroscope and accelerometers inside with a downward-facing ultrasound sensor all working to make for generally stable flight. The Mambo comes with blade protectors that are easy to pop on and off and when you first start flying it around they’re an essential addition.
Cannon
Interact with other drones and pilots using the included Cannon accessory. Attach the Cannon to your Parrot Mambo and let the games begin! Test your skills with target practice, and fire these little balls at a pyramid of cups or other light-weight targets. You can load up to 6 pellets into the Cannon at a time. The first pilot to knock everything down wins! This feature is very similar to Xiaomi mi drone 4K.
Grabber
Attach the Grabber to the Parrot Mambo and use it to transport mini-objects that weigh up to 4g to a new location. Simply activate the claw on the home screen of your FreeFlight Mini app, carry something up into the air, and put it down wherever you want.
Safety First
Thanks to an advanced flight controller and high performance sensors, the Parrot Mambo is easy to pilot and control. In addition, the autopilot functionality ensures that it will stay stable and hover, even if you let go of the controls. Lastly, the Parrot Mambo comes equipped with and automatic ‘shutdown system’ that cuts the motors off in case of a crash or collision.
Remote Controller
The controller looks and feels like a simplified Xbox controller, with two multi-direction sticks that control rotation, elevation and motion. There are a couple of buttons that activate special acrobatic moves (which you may want to avoid performing with the headset on, unless you have a barf bag to hand) and a button for take-off and landing.
Camera

The 0.3-megapixel camera really is not great. Think an old VGA webcam level of quality and you’ll hit the mark. It’s noisy and blurry and the colours are underwhelming. Still, it can still be relatively fun to get a top-down view of your living room. 
Battery life and charging
Best case scenario -no hull, no accessories -and you can expect up to 9 minutes of continuous flight. Throw in the extra weight of the hull and accessories and I found this closer to 6-7 minutes. Not amazing, but enough to have a quick round of fun. Thankfully, charging only takes 30 minutes when connected to a 2A USB adapter, which could’ve been worse.
You can pick up a spare FPV battery for less money. I would have said it’s worth stretching to the battery plus battery charger pack so you can be charging a second battery while the drone is in flight-otherwise the battery needs to be attached to the drone to charge. However, Parrot says this charger dock takes 1.5 hours to charge a single battery, which negates its usefulness.


Pros
  •  Fun and easy to fly
  •  Reasonably quick charge time
  •  Easy to set up
  •  Fun accessories
Cons
  •  Short flight time
  •  Mini pellets are really easy to lose
  •  Can only lift 4g using grabber
  •  Doesn’t do well in even light wind

Black Talon FPV Quadcopter

Black Talon FPV Quad is a RC drone for indoor flight, it has a good comprehensive proerty, but its flight time is too short.The drone has gradually become a mainstream digital gadgets, not only take the aerial photography, surveying and other specialized work, even to the competitive direction. For ordinary people, the UAV can also be a great relaxation activities, especially the cheap, easy to use model.
black-talon-fpv-quad-01
Black Talon FPV Quad is a four-axis compact indoor drone, its price is about $ 139, it iVery suitable for use at home. In addition, it also equipped with a camera, to take pictures and video,Now let’s take a  look at their experiences below.
black-talon-fpv-quad-03
Black Talon FPV Quad has black body, overall is very small, propeller parts has bezel with security, can easily fly in complex family environments. It uses WIFI signals for remote control, frequency is 5.8GHz, it has tested their disturbance is very good, do not conflict with other wireless devices in the home, and the latency is very low.
Black Talon FPV Quad with a wireless controller that handles look like the Xbox One handle, also has a monitor LCD screen to monitor flight. In addition, if you don’t like the RS button on the handle, you can also replace the lever, it is very flexible.
About the battery, Black Talon FPV Quad equipment with a 520mAh lipo battery, it provides about 5-6 minutes flight times, it seemed not very good. Of course, users can buy some other more fast batteries to replace it, I recommend pilots can choose the Tattu fpv batteriesTattu 450mAh 11.1V 75C 3S1P Lipo Battery and Tattu 850mAh 11.1V 45C 3S1P Lipo Battery is very useful to Black Talon FPV Quad, it can last more long, flies more long time .
tattu-450mah-3s-75c-lipo-battery
tattu-850mah-3s-45c-lipo-battery
Black Talon FPV Quad has three sensitivity settings, medium and high settings of the more suitable for outdoor use, after all, need to take into account wind speed cause yaw condition. When used indoors, Black Talon FPV Quad signal penetration is excellent, even flying into the basement in the single-family homes and almost no lag, LCD monitors are also very easy to use.
black-talon-fpv-quad-04
Due to wing has designs of crash, even hit the shelves, cabinets and also not so big problem, airborne and pressure sensor provides excellent flight stability, no one in the small indoor four-axis machine is still relatively rare. Of course, 5-6 minute range is its greatest weakness, maybe you just fly enough, need to replace the battery.
Black Talon FPV Quad is a comprehensive performance, value for money and it is very good in-room , flying and shooting are very satisfied, in addition to poor battery endurance.
