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...

Okay, this is what to do with a brass knurled nut and two matching socket head screws........ Make a compact tubing bender for 1/8" soft brass tubes. Made bending the tubes for fuel tanks so much easier.

I received and installed the Dragon Link Nano receiver in my quad. This enables basically unlimited range, which is unnecessary on a small race style quad, but it ensures that I should never get drop outs when I'm flying around obstacles, or if I do feel like pushing it out just for fun.

I got some flights in after the installation. Since I'm new to quad flying, it is very difficult for me to fly in a tight area like in these videos. I need a lot of practice to gain some confidence for getting closer to obstacles. I find it really easy to get going too fast, which is why I crashed in the first video. I also noticed that the video performance was quite bad. A higher gain receiver antenna will definitely help in the future.

The FAA has released the newest Aerospace Forecast, and there is no surprise that major growth is predicted for the drone industry. The Unmanned Aircraft Systems section of the Forecast reflects both concerns and optimism for the sector. The FAA says that while robust growth in the sector and the introduction of UAS into the NAS has opened up numerous possibilities, it has also created unique operational challenges. Despite these challenges, the UAS sector holds enormous potential, with commercial applications ranging from aerial photography to package delivery.
