"Very encouraging rules. They seem very reasonable from the perspective of both air safety and allowing American UAV development to really take off. "

Help, please, with RFD900a radio that appears to be bricked

Hi folks,One of my RFD900 radios was working fine for months but is now only showing 1 solid red LED. Using USB/FTDI, I'm unable to connect or reset it with MissionPlanner ("No heartbeat packets received") or with the 3DRRadio.exe ("Failed to enter command mode") config tool.I've tried all the baud rates and even tried different USB ports. The other RFD900 connects just fine using the same USB/FTDI connection. Any suggestions on how to troubleshoot this? Or how to reset the device? Thanks in…See More

Hello,



I've been silently following the progress of the UAV Dev Board team for a while now, and want to congratulate Bill Premerlani and his great team for their amazing accomplishments.



This is my first posting, so please let me introduce myself. I'm relatively new to RC flying, and have very little experience with micro programming, but do have some background in aerospace and software engineering. Anyway, after crashing a few planes, it's exciting to see that such a… Continue
