RMILEC Signal Converter V3 SBus PWM PPM

RMILEC Signal Converter Signal Analyzer V3. If you want to test or fly with a SBus receiver without a flight controller the old fashion way, you are in luck; this signal converter is able to convert SBus signal into PWM signal and two-way PPM signal.  It can also convert PWM signal into PPM signal and SBUS signal, or convert two-way PPM signal into PWM signals and SBUS signals.  Amazing!  I will take some video to give you some ideas of what you can potentially use it for, probably more ideas than I can suggest.

Besides debugging signals, we plan to use the FrSky R9 MM, the latest long-range 900MHz mini receiver on a plane, so one option is to use RMILEC signal converter and connect directly to each servo leads.  The RMILEC Signal Converter carries a small footprint, about a size of a SD card.  There is also an older version that incorporate a LiPo alarm of this converter, in that way it also function as a low voltage warning system…

XK A110 Predator MQ-9 EPP Glider 565mm

XK is one of my all time favorite manufacturer that makes ready to fly (RTF) self-stabilized drones.  This XK A110 is modeled after the Predator MQ-9 drone using 3 channels.  XK A110 Predator MQ-9 is very light and uses differential trust, just like a quadcopter, to power the turns instead of using a rudder. Two small propellers, one on each wing. A little disappointing, the back larger propeller is just a dummy prop that only adds some drag.

The pusher propellers are dual-engine powered and rotates in opposite directions to cancel each other out of the counter-torque; that keeps it more stable and in path. Comes built-in a 6-axis gyroscope flight auto-stabilization system with dual rates, allowing me to perform some aerobatics such as loops…

FrSky Taranis X-LITE Review Spring Unloaded

Frsky taranis x-lite

Introducing the FrSky Taranis X-LITE, the ultimate gaming radio transmitter. Made to match the ergonomic modern design of a gaming remote control, this radio transmitter has all the capabilities of a traditional radio and more.

One advantage of this FrSky radio is I can switch out to a R9M 900MHz frequency system for long range, low latency, going as far as 10 km.

First impression is good, it is more refine than anticipated.  The speaker sound is so much more superior than the Taranis X9D .  Equipped with the latest M12 Lite hall sensor gimbals.  Hall sensor gimbals are more precise and durable than traditional gimbals using potentiometers.  The switches may feel a little too small, but for casual flying (not competitive racing), this radio does just fine…

FXT Mars S T71 Micro FPV Camera 1000TVL

Introducing the FXT Mars S T71, easy to setup 1000 tvl fpv camera. In a nutshell, it shows me the voltage and that is a big win for me. The color production and sharpness not so much.

This little camera comes in various colors and displays the voltage balance on screen. Orange and red color is an added advantage to help me locate a lost camera in an open field. Wide-angle, as I can see the cockpit from the wing, on a plane.

Input voltage DC4.8V to 36V allows me to safely power up from the main flight battery or a secondary battery. This camera is super small, about a size of a penny, and lightweight. It is wired ready with a standard JR transmitter signal, ground and power cable. The power cable is separated, so you can power your camera in various ways. However way you decide to power up, keep in mind the screen will display the voltage, a useful feature that is built-in…

F2S Autopilot GPS OSD RSSI All-In-One Flight Controller

Amazing F2S all-in-1 flight controller, I think this is worth sharing.  The F2S coverts your fixed wing planes into a drone with GPS return home.  In addition, it adds all the telemetry information on your screen.  Best of all, no tuning needed.

We configure the F2S on an Eachine Mini Skyhunter Racer for this episode with a Mobius Mini. It does a nice turn on Return Home and circles in a 8 formation upon returning and begins to climb that 328 ft (100 m) preset. I have been flying this plane without Gyro, so at Manual mode, I still retain the full experience and know I can bail out at any time. The Mini Skyhunter is a fast plane, I noticed the Heading Mode seem to zigzag-drift occasionally, other than that, the rest is good so far. I get the most 11 GPS satellites so far. Here is a video of everything you need to get setup.

Pros – can be installed and tested under an hour, multiple flight modes and comprehensive OSD
Limitations or maybe good – little customization or tuning available or needed. Setup by radio, no computer required…

Eachine Mirage E500 VTOL Vertical Take-Off Landing

A vertical take-off and landing (VTOL) aircraft is one that can hover, take off, and land vertically. Eachine recently released a budget Mirage E500 VTOL Wing, and this is great venture into the next generation of radio control aircrafts.  When I can take-off and land vertically, I don’t have to worry about a runway.

We received a bind and fly sample to test, and with it includes a basic 3rd party FrSky receiver to complete the tests…

ZEROTECH Dobby 2 Pocket Selfie Drone

The highly anticipated DOBBY is here and in our lab, compact and optimized for photography, taking pictures by voice control and gesture control, assisting users to capture the perfect selfie “Kodak” moment of this generation.

DOBBY Pocket Drone is an AI-powered drone using Qualcomm Snapdragon 801 chipset, piloted with GPS and GLONASS, featuring object tracking and facial recognition. DOBBY can take off by voice control and one click on APP. Selfie lovers can enjoy creative photos from unique perspectives rather than taken by other shooting tools like cell phone cameras.

If you are into smartphone technology Qualcomm comes to mind; anyone who uses Wechat or QQ knows what Tencent can do.  Known to few, the two giant firms are among the core influence to bring ZEROTECH to the limelight with Dobby. However with all that investment backers and publicity behind it, there seem to be an underlying issues uncovered as we take it for several tests.
