Bobby replied to Bobby's discussion VTX Interference in IRIS
"Hey Steve, totally agree after some functionality testing (described by David above), I decided to go another route. I didn't notice any real interference issues, however I just wasn't comfortable with it.
My original purpose for mounting it under…"

"How do you mount your camera? Do you have a gimbal? I'm trying to figure out how to mount a jello free Mobius without the long legs."

"I thought about doing it like that too. If this doesn't pan out, I may go that route. I like having the VTX on the outside to get it away from the other electronics and it will also get massive airflow to keep it cool."

"Hey Paul, just saw your pic. Nice clean install. Have you tried inverting it to see if you get better range? Also thanks for posting the install video.

I'll try reposting my pics. (FYI: haven't screwed down the case yet in the last…"

I'll describe how my install in the meantime. I mounted transmitter opposite/mirrored to the telemetry radio. I then ran an antenna extension…"

Bobby replied to Bobby's discussion Telemetry Link in IRIS
"If I'm reading the attached logs correctly, it looks like to me that the RSSI increased every time the BarAlt increased. I don't see where it dropped out.
In the future I plan to bring my MS Surface with me as a ground station. Should help with this…"

During my first few flights I noticed that I would lose telemetry on the radio when the aircraft was around 100ft in elevation and I was standing, not quite underneath, but in close proximity.When I flew at lower altitudes and over 400ft away from…

Bobby replied to Bobby's discussion Parallax Ping + Arduino
"This may be a ground issue. After some more troubleshooting I found that if I wiggle the ground or touch different metal parts it reads very accurately. I still can't get stable readings though.

Anyone have experience with these?"

Hello,I'm having trouble getting proper readings from a Parallax Ping. I've followed the tutorial on the Arduino site with no luck.The problem I'm having is the readings in the serial monitor are mostly 0in or 4in. It never changes with different…
