If you wondering what is the difference between a SMA and RP-SMA connector and which antenna you should choose for your transmitter or receiver, here is my short and clear answer: The RP-SMA connector is a variation of the SMA connector and has the same external housing. The only difference is the gender of the

As Cleanflight firmware is getting popular among the multirotor pilots, I wanted to make a summary of the flight controllers that can use it. The question is not anymore “Naze32 vs. CC3D”. At the end of 2015 there are more powerful flight controllers with additional features. All supported flight controllers use STM 32bit processors. Most

Here are my 10 Tips for better performance and longer life of your LiPo battery. It is good to read the basics about LiPo batteries first. Don’t over discharge or over charge the cell. Minimum voltage (Vmin) should not drop below 3.3V and maximum voltage (Vmax) should be 4.2V (4.35V for HV batteries). If you

LiPo batteries are the power source for most RC drones. If you are going to build your first drone, want to achieve longer flight time or have better performance in a FPV race you need to understand the LiPo batteries technology. General Information LiPo stays for Lithium-Ion Polymer battery. These are rechargeable batteries with three

Have you experienced slow side drift on your quadcopter? Or maybe a yaw drift? To achieve a stable hover of your quadcopter first your RC Roll, Pitch and Yaw channels must be at the default midpoint of 1500μs. To achieve this, calibrate your transmitter sticks (if you have never done this) and then use the

I will try to keep it super simple (KISS) and explain why an ESC without BEC is not necessary an OPTO ESC. BEC stays for battery eliminator circuit. It is an electronic circuit, which delivers power to other electronics, like your flight controller or receiver. That is why we connect the red wire of the

If your frame is not a standard X or H frame, here you find the basics on how to configure your flight controller for this custom frame. There are two methods about getting the right values for your controller. The first one is by using the angles between the arms and the Roll and Pitch
