Does the latest FrSky R-XSR firmware break SBUS? I found this to be true as I was troubleshooting why my brand new R-XSR that was flashed to the latest firmware (3/8/2018) was not working. I replaced it with another brand new R-XSR that was not flashed to the latest firmware and SBUS worked flawlessly. I later found that a friend of mine had the same issue. He put together this alert for anyone who is having issues with their R-XSR and SBUS. Comment if you have had the same issue.

The Mantis 85 is a mini brushless racer that comes truly RTF (ready to fly) as it includes even a FlySky FS-I6 hobby grade transmitter beside having a battery, a receiver, preset flight controller (PID) and even the TX bound to the RX ! The only thing missing is actually a LiPo charger and you can literally fly this out of the box. How does it perform ? You will see in the video.

Main Specs & Features:
- 3K full carbon fiber bottom plate set up with CNC aluminum alloy stiffeners, more durable and strong
- STM32F405RGT6 MCU BLHeli - S ESC provides stable power
- Adjustable angle of the FPV camera
- Supports Acro mode / Air mode / Angle modes
- Built-in OSD
- Radio stick to control PID tunes / FC settings.

Product summary

The pw-link data transmission module is divided into built-in antenna and external antenna version. The built-in antenna version is only suitable for pix flight control near distance and regulate the use of the calibration parameters, and the external antenna version after a number of practical test and reasonable transmission distance is 450 meters. The use of computer mission planner ground station for a long time the connection test, average stability data the transmission signal is maintained at more than 90%. Because of its small size, long transmission distance, stable data, convenient connection characteristics, very suitable for small UAV data receiving several hundred metres.
PW-Link The whole communication mode is as follows:

When you are hopelessly hooked on the rc hobby and you loose your job of 43 years due to failed back surgery and your income drops by 75 % you have to get creative to stay in the hobby. Thanks to people who care i was able to start a mobile hobby shop and Face book store called Born Again Rc Airplanes. I make enough to keep a few planes i can call my own. So i thank GOD i can still fly. So if you wonder why i am selling a plane it is so i can keep doing the hobby i love. I caint imagine not flying. Like i tell newbies its the only hobby where you need sunscreen for your teeth. Cause your always lookin up. Cheers.

I have a slight tail-kick that occurs only in the wind, and through some research I've found it reported that reducing the "I" tail gain on the model's FBL unit, from the stock 100 setting to 90, has cured this issue for some folks.

Changing the tail "I" gain settings on the B130s was pretty easy. I turned on the TX (in my case a DX7s), flipped on Throttle Hold, then mounted and plugged the lipo into the B130s. After it initialized I held both sticks in the lower right hand position and pushed the bind button in.When the servos moved I released the sticks and bind button. This put the model into gain setting mode. I rolled the thumb wheel on my dx7s to the right until the telemetry screen appeared on the tx and then to the right once more until the flight log appeared. I moved the cyclic stick to the right until parameter #6 appeared (this is tail "I" gain). Then I moved the cyclic stick down to reduce the gain from 100 to 90. The gain-setting line for this parameter is "B." To save the settings I pushed the bind button in again until the servos moved. The directions were in the manual and seemed to work great...

I then flew a couple of packs in a 7mph breeze. It was sunny and 28degrees F. Reducing the Tail Gain "I" from 100 to 90 seems to have done the trick with the tail kick. Of course I need to put more packs through it to be certain, but I'm pretty sure the tail hold in the wind is improved...
