GoPro Session is getting some serious and cheap opponents:

100$ RunCam 3 HD 1080p/60fps NTSC/PAL 155 Degree Wide Angle WiFi FPV Camera

Interesting about this cam is its dedication to FPV: beside HDMI out, it has also analog TV out, as old SJ4000 had. So it can be used to parallel record HD footage and send via VTX analog signal to ground LCD or FPV googles. In packet comes Micro-USB TV-Out cable. Nice



I really like the slogan of RunCam3 "Born for RC fanatics" as I think of my self as one. I hope it will be able to meet the expectations of us. More test video to follow. I am waiting for 3D printed holder for my RunCam3.

Full Review - FrSKY XMPF3E - F3Evo Flight Controller with integrated full range XM+ receiver

Intro:

Modern trends on quad scene are going into miniaturization and integration of electronically flight elements into combo.
First appeared 4in1 ESCs, which I really like because I think they make possible better and cleaner builds.
Than PDB+FC+OSD combinations came etc…
With appearance of tiny whoop micro style quads I saw combination of FC and receiver and I own QX70 70mm and QX90 90mm micro quad which came as BNF version with F3 brushed FC with integrated D8 FrSky compatible receiver and it works great.

Now FrSky joined this style and made this great product XMPF3E - F3Evo FC with integrated full range XM+ receiver.
I am very excited about this product as it will enable us super light and clean builds of which I am great fan. Especially, XMPF3E in combination with 4in1 ESC (with onboard 5vBEC) build will look super clean.





Specifications XSRF3E (taken from FrSky site):
  • Dimension: 36366mm (L W H) with 30.5mm mounting holes
  • Hardware: STM32F303 CPU (72Mhz inc FPU), MPU9250 (accelerometer/gyro/compass), and BMP280 barometer for F3E
  • Weight: 5g
  • Channels: 16CH (8CH is RSSI) by SBUS to UART2 Rx of F3E
  • Operating Voltage Range: 4.0~10V
  • Operating Current: [email protected]
  • Compatibility: FrSky Taranis X9D/X9D-Plus/X9E/ Horus X12S/XJT in D16 mode
  • Firmware: Upgradeable




Features:
  • Built-in F3EVO and XM+ receiver module

Video of unboxing, pairing of cell A, usage and overview of menus:
Charsoon Magical Core LCD Battery Charger with Cell-A 2-6S Balance Port (22 min 36 sec)




My new home charger just came
Its modular design is quite unique, interesting and I really like it.

One use case immediately struck my mind as I was connecting Magical Cell-A to Magical Core: to buy 1 more of Magical Cell-A's and get pretty cheap 2 channel charger and be able to independently balance charge 2 batteries at once with 1C charging current, awesome

The charger can charge and charge to storage different batteries. Its very easy to use, as soon you plug in the battery it automatically starts selected function.
Great feature, that some of chargers miss, is support for LiHV 4.35V (LiPo High Voltage) packs.





Specifications of Magical Core:
  • Input Voltage: 11-18V
  • Charging Power: Max.50W x 2
  • Charging Current: Max 5A x 2

Features of Magical Core:
  • Compact size, snap-on design between two magic cube cell, easy to carry.
