Radio hardware for Pixhawk

I just received a 3DR x8 that I planned to use with some existing Spektrum equipment that I have. I have decided to keep that equipment where it is and get something dedicated to the X8. After doing a little reading I think I want to utilize a PPM-su

Is there a simple way to convert the time stamps in either the ArduGCS ot the Happy Killmore GCS data files into real time? I need to be able to have the actual time so I can tie it to the photos that were taken at that given instance.

relocating gps inputs on the IMU

The connector for the GPS cable was torn off my IMU in a crash. Are all of the connections for the GPS available somewhere on the header slots so I can rewire? I can get continuity on all but one but on that one the solder pad was torn off and I'm no

missing ublox antenna cap

I had a hard landing today and I noticed after I got home that my Ublox GPS is missing the antenna cap. I won't be able to go back to where I was flying for at least a week to search for it. Is this something that is replaceable? I thought I saw anot

Successful Autopilot flight with Hawkeye

Yesterday I had a successful stabilization and RTL with my Hawkeye. I've attached pictures of a Hawkeye in case you are wondering.

This airframe is very sensitive to wind. So I try to stay out of anything more than 12-15 mph. Winds yesterday were at m

GPS & IMU

FTDI Cable ?

The FTDI cables are out of stock in the store. I've got the rest of my hardware and need the cable very soon. Any other sources for these or is it possible to splice one together?

Would buy one if anyone has any extras for sale.

Thanks!

Hello everyone. It's been a month or more since my last post. Rather than modifying an off the shelf airframe for my dissertation aerial photography work, I decided to scratch build an airframe. RP Flight Systems was kind enough to let me visit their
