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 a scale model of the Predator MQ-9 drone using 3 channels.

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 roll.  More updates to come …

Motive-RC R8SB Telemetry Receiver on Taranis X-Lite

Motive-RC R8SB

I still fly lots of planes the old school way, without any flight controllers, so this Motive RC R8SB all-in-one receiver even though a D8, it allows me to use my Taranis radio transmitter and most of the features.  Add a voltage sensor and I am all set.  The receiver comes with various model type SBUS, physical channel PWM outputs, PPM and RSSI.  The RSSI warns me about the signal strength before I fly too far out.   Here is a video on how I add a RSSI bar to my X-Lite screen using the Motive-RC R8SB.

The R8SB is like the FrSky V8R7-II receiver but with telemetry functions.  It bound instantly and lights up like a green lantern. There are more pins than a usual receiver, but they are nicely color coded to help me determine signal, power and ground.  The upper set of pins are your 8 channels or SBUS/PPM.  The lower set of pins are RSSI, two analog telemetry ports (A1&A2), A1 for internal receiver battery voltage sensor, A2 for external battery voltage sensor (0~30V, 1~6S) and one digital data-stream port (Rx, Tx)…
