Upgrading Turnigy 9X8Cv2 receiver

|
+0
Hello, dear colleagues!

Just a couple of days ago I did a little upgrade to my 250-size copter. I decided to supplement it with a sonar and a GPS receiver. However, I realized that the Naze32 flight controller had too few unoccupied legs, when I was connecting the receiver in parallel-PWM mode… That was hardly a big issue, and it could be solved easily by installing a PPM-Sum module. AliExpress and other stores are crowded with them, but waiting another month did not sound like an attractive option to me, and the all-go-know Google suggested that it could be made of an Arduino (which I had galore) by way of a few simple soldering manipulations...

My two-dollar Arduino Nano RC key.

Hello, everybody! I’m here to present my own RC key, which I connect to the receiver, so that I can control heavy load. I saw different versions on tiny13 and atmega328, and I realized that a Tiny13 would be too low on memory and it could put me through a lot of nickeling and diming; an Atmega328 would cost me almost as much as an Arduino Nano. I also wanted a simple and familiar Arduino IDE, so I’d be able to quickly reflash it via USB.

I decided to make it open source and give other users an opportunity to build and modify it to suit their needs. I chose a two-dollar Arduino Nano microcontroller, the smallest one.

This is how it works:

Pete n Poke made of ceiling tiles.

Hi there! Once I came across the model of a parasol two-sitter «Pete n Poke». It was made of balsa with glow-engine.

I was eager to make it myself but out of ceiling tiles. I decided to cover it with tracing paper on an aqua lacquer base and paint with acrylic spray to make the outline look nicer. It should be noted that I didn't plan to copy it. I simply wanted to make a nice retro model. The motor used was brushless TURNIGY NTM Prop Drive Series 28-36 1200 RPM.
NTM Prop Drive Series 28-26 1100kv / 252w

Wing spread chosen was 1100 mm, fuselage length – 938 mm. I scaled it and changed the drawning due to the usage of ceiling tiles.

Polikarpov Po-2 - the Heavenly Slug

Now that I have crafted a dozen of ceiling tile models, it is about time for me to build a big chugger with a trail of smoke behind it! Without much hesitation I chose a legendary WWII vet – the Polikarpov Po-2. I wanted to be honest, so I decided to build it from wood and cover it with doped fabric and try not to overweight it. Also, I wanted to test my DIY CNC. I hammered at drafts a little, which I had fished out of the web (those were just common views from three angles) and started sawing.

FPV from Scratch in Detail.

The whole thing started on a cold and snowy evening. I was having fun after another busy workday at my PC browsing for all sorts of RC hobbyist goodies, as I was about to start building my new plane. When I was well into yet another attempt to comprehend the section describing telemetry equipment, the idea of building a FPV dawned upon me. After a brief consideration, I was fully determined to add my first FPV to my arsenal.

Rewinding a 2205 Brushless motor.

Hello everybody!
It’s three years since I’m in the RC hobby, and it was then that I got this kind of motor. It was intended for the well-known Cessna 150. Then it was incorporated into an overseas 4Q, then – into a Vzhik, and now it is installed in a Kesla. Although it has come through snow and water and gave a smoke, it was all right until a few days ago. It was down after I flew my KESL a few times. I guess that is due to winding damage or something like that. Well, that’s not important now.

Essentially, I had to check them.

Hello everyone!

I'd like to share with you my experience of building La-7 fighter plane model. I used styrofoam because the time until the contest was short and there was no way I could make the dummy to build the model out of plastic bottles.
I'll keep it brief, if you have any questions, ask away in the comments below, I'll reply.

Testing the Multistar High Capacity 4S 10000mAh Multi-Rotor Lipo Pack

The new line of Multistar High Capacity Batteries hit the market last summer. I chose not to rush, because I didn’t want a pig in a poke and looked for user feedback, but that made the choice even more challenging. Eventually, after six months I did buy a Multistar High Capacity 4S 10000mAh Multi-Rotor Lipo Pack just for experiment: Multistar High Capacity 4S 10000mAh Multi-Rotor Lipo Pack
