When I power everything up, the receiver recognizes the radio, the servo moves but when I use the radio nothing happens. What gives? It's a 3PM FM used sparingly. I even tried a different servo and the different channels on the R133F.

If using an electronic ESC, check to ensure it's programmed/sync'd to the radio. Recommend going back though all your radio setup and connections to troubleshoot and ensure the servo is connected to correct Rx channel. Hope this helps.

Make sure the servo connector isn't plugged in backwards. The center is power "+", one side is signal, and the other ground. If the signal and grounds are reversed, the servo won't move.

Hmm with my radio gear, all I was trying to set up was the steering servo to trim it out, so the ESC wasn't in the picture. Everything connected to the receiver is a Futaba J connection and they are definitely not backwards. I just powered the receiver up with a receiver pack and plugged in channel 1. All the batteries are pretty fresh and I just used the plastic receiver pack that accepts alkalines.

I've been through the manual and the troubleshooting page is only one page long lol.

It was set in HRS. I'm good!
