Review of Giant Power DINOGY MEGA GRAPHENE 2.0 1550mAh 14.8V 75C Lipo Battery

Graphene is the very latest ‘wonder material’ for nano class batteries, bringing with it a range of attributes which lift battery performance to a new level.

Graphene is a honeycomb lattice of carbon atoms, and is a potent conductor of electrical and thermal energy. When Graphene technology is added to Lithium batteries, the ions are able to move much more quickly between the positive and negative electrodes. This boosts the battery performance in every respect and, because of Graphene’s astonishingly light weight, there is no weight penalty. In fact, there is a weight saving!

‘Graphene 2.0’ technology allows to produce market leading Lithium batteries with higher energy density (lighter weight and higher capacity), higher under-load voltage, higher reliability and precision cell matching. As every drone racing pilot knows, light weight and higher output voltage are vital if you want to stand on the podium: The DINOGY MEGA Graphene 2.0 is your route to racing success!

  • Brand Name: DINOGY MEGA GRAPHENE 2.0
  • Item Name: Lipo battery
  • Cells: 4S (14.8V)
  • Capacity: 1550mAh
  • Constant Discharge: 75C
  • Max Charge Rate: 8C

Review (ip) of Holybro Kakute F4 AIO All in One V2 Flight Controller STM32 F405 MCU Integrated PDB OSD for RC Drone

I got this Kakute F4 AIO v2 for my upcoming 6S build because this board supports up to 6S, has built in OSD and PDB (up to 120A), and according to the manual it has 5V, up to 1.5A BEC which should power receiver, FPV cam and VTX (even a high-powered VTX like the Unify Pro), lots of UARTs, buzzer pads, voltage and current sensor.
In short, everything one DIY quad builder would wish from FC and all that in simple and well thought PCB layout with nice price tag.

When I am already mentioning the manual: Congrats Kakute on awesome manual!!! - English Manual is HERE.
Whish more RC electronic components would come with this high level manuals.
For sure, there would be less white smoke flavored PCBs and hours wasted on figuring how to connect or configure boards.

I will be using this 6S compatible components:
  • Kakute F4 AIO v2 - product link
  • 2207 1700kv motors designed specific for 6S - product link
  • Gaoneng GNB 1100mAh 6S 130C 22.2V Li-on Lipo Battery XT60 - product link

Review of Xiaomi MiTu WiFi FPV With 720P HD Camera Multi-Machine Infrared Battle Mini RC Drone Quadcopter BNF

Did a quick indoor hower test and quad flies perfect. Height hold is super precise. Position hold is also great, quad holded its place without stick inputs flawlessly.
I had only small and slow yaw movement - oscillations, left to right.

Warning: my Galaxy S7 (Europe SGS7 SM-G930F) couldn't find WiFi network of MiTu.
It works with my Lenovo Tab 4 8 Plus (TB-8704F/N) and my wifes iPhone 6.

Review of Eachine E010S PRO - 65mm 5.8G 40CH 800TVL Camera F3 Built-in OSD High Hold Mode RC Drone Quadcopter

This quad remained my on the Jaws. Too bad it cant go underwater

This cool design aldought brings great benefit for beginners because all electronic parts are well protected in canopy it makes life a little bit complicated (we are spoiled) to initially setup the quad because bind button for RX, CH/TX button and USB port are all hidden under canopy.
Good thing is that after initial setup there's no need to do that again because quad has OSD so most important BetaFlight settings are tunable via OSD.

I can reccomend this quad already to beginers because its great protection of el. components and antennas.

VTX antenna is hidden in shark tail ant RX antenna is laid horizontal "out of the box". When I opened the shark to adjust my CH/TX I put the RX antenna to upright. I believe it should be better that way.

I did a short hover and LOS test after setting in BF my modes and it flies great.

Flight video footage :

Maiden "out of the box" flight.
Flies just awesome...

Review of JJRC H62 - Best flying selfie drone jet - Target Tracking and optical flow positioning foldable drone

Upgraded model of H61, H62 with code name SPLENDOR is here:

H62 flies great. Yaw response is beautiful, which is not the case on most selfie drones.

Position hold via implemented optical sensor works perfectly. I had to give zero stick inputs in hover, check OSD view from the captured phone screen - post #3.

Review of Dragonfly Hurricane 2207 KV2500 Brushless Motor for FPV Racer from FPVmodel

Doesn't this motor look great?

Build quality of these motors from FPVMODEL look amazing. Especially when taken into consideration their price.
Quality/price ratio on this motor is huge.

Hope their performance in flight quality will be equal to their looks&build quality.
A great feature is also plastic ring along the bottom part of the windings that will prevent bolt, which is too long, to push against windings and damage the motor. What a great and simple idea.

Air gap is nonexistent and on the bottom side of the magnets here are blobs of glue used to balance the bell. Also, another important aspect is that vertical play is nonexistent also.
Bearings sound nice and smooth.
