QuadMeUp Crossbow LRS: introduction
Few days ago I mentioned that I'm working on my own DIY long range radio system (LRS) that I named QuadMeUp Crossbow LRS. Today I will share some more details about it.

Project Dualcopter – worklog #3
It's been exactly one year since my last update on Project Dualcopter. On 20th of October 2016 I've posted that there was a progress.

3D Printed Paddle Wheel Boat
It’s not a secret, that me, and QuadMeUp, are not only about quadcopters. From time to time I like to do something completely different. When I was a child (10-12 or something like that) I loved to build boats. Simple crude design: styrofoam or bark, simple sail or DC motor and tinwire propeller. No RC…

3D Printed Faceplate for SkyZone SKY-01 FPV goggles
While SkyZone SKY-01 are pretty good FPV goggles, they are not very comfortable. Instead big faceplate, they only have rubber eyecups. This approach works, but well… Like always, there is a solution: 3D printed faceplate for SkyZone SKY-01. Thingieverse has at least few different designs, but I’ve chose the one from the link above. They…

So I had a choice: buy original battery from RunCam for $9.99 plus shipment, or fix it DIY style. I’ve choces the second option. Luckily for us, RunCam used generic 803035 LiPo…
