another quick question about RTH... I'm looking at the code and trying to understand what happens during a GPS NAV event, such as RTH, if the GPS fix is temporarily lost (possibly due to issues with the serial link and/or if the sat count drops below 5). For example, it *appears* that an RTH action...

I'd like to please make a feature request for WinGUI... please add a 'baro calibration' button in order to manually re-calibrate the barometer.

I don't want to be rude, but I cannot put countermeasures into the code against gross negligence..... If you reflash your controller NEVER assume that your EEPROM content is still valid, and most importantly NEVER assume that your mission is still valid.

Hi all, great job EOSBandi, I have some questions about my QUADX with the MW2.3 navi B7 software.

Hi, when using the 433 MHz telemetry from HK or RCT then the ground station local noise is very high (80dB) and affect range significantly.

Is it possible to have autoland on atmega328p ?

Nope, you need an atmega2560 FC for that.

OpenAerial appears to be discontinued (and was not at very useful scales anyway). It is possible to patch the mapping library to support Bing (subject to the usual discourse on whether the Bing ToS allows this, but lets not go there). I know that it is not fair, but mission planning without sat ima...

THere are two basic types of faisafe receivers. With the sophisticated ones such as Frsky, Dragonlink etc. you can preset values for each channel, and the receiver will set these values when lost communication.

Tired of the "try add some weight there" method in prop / motor balancing i realized i need better data to balance the stuff. The 80ms interval of MSP_RAW_IMU gives us 12 values/sec, 720 values/min, or about 300 RPM max. I need much faster data. One value every 4ms gives max 6000 RPM, whi...
