[Advance apologies for the epic.]
This afternoon I’ve taken delivery of a Radiomaster TX12, an Emax Nanohawk and some FatShark Recon V3 goggles. I’m an hour in and it’s clear I haven’t got a clue what I’m doing.
I’ve watched a few videos on YouTube including this one and this one. The first is very comprehensive but is demonstrated using a couple of drones that are not the Nanohawk. The second is a Nanohawk, but I suspect there’s a lot of detail missing in his glib, “I’ve got the controller set up so I’m ready to fly”. And I’ve watched this one, which shows how to activate the binding mode on the Nanohawk but is a different controller.
I think I’ve got the controller bound to the drone because I get the voice notifications about “telemetry lost” and “telemetry recovered”, but the red LED on the underside keeps flashing, which the guy in the final video seems to think means it’s unhappy with the switch positions. I’ve tried the switches in all different positions. Nothing seems to do anything.
So I was thinking maybe I need to do something with the OpenTX Companion. Fired it up, plugged the controller into a USB port, switched it back off and back on with the trim levers in position when the companion told me to, plugged the USB back in, downloaded the firmware image when asked, but it still kept saying it couldn’t detect the controller.
I suspect I may be missing a few large pieces of the jigsaw.
But before I can start looking further I notice that dreadful hot plastic smell. I instantly assume it’s the drone battery, as I’ve had it plugged in because I think it’s gone flat while I’ve been faffing about, but that’s cool as a cucumber.
No, it’s the controller. The right hand side of it near the roller switch is scorching hot. I immediately unplug it from the USB and open the battery compartment, worried it’s the batteries overheating, but they’re cool, too. It’s (presumably) components in the unit itself, and there’s a few wisps of smoke coming out of the battery compartment.
I’ve now let it cool down, put the batteries back in, powered it back up and it seems to be working as well as it was previously, in that I can bind to the drone and it warns me that I’m still connected if I try and switch it off before powering down the drone.
But I’m at a complete loss as to what to do now. I’m guessing the controller configuration is not correct for the drone and I thought the OpenTX Companion might shed a more user-friendly UI on that. I’ve also now found the Nanohawk use manual which lists the stock flight settings, so I’m guessing I need to map these into the TX12 somehow. I also note that it says it is TAER, rather than AETR that the videos I’ve been watching seem to think is standard.
Do I also need to be messing about with Betaflight, or should I be able to get this working without all that?
Honestly, this isn’t a learning curve, it’s a learning cliff.
(I’ve just spent 20 minutes in LiftOff with the controller plugged in as a joystick and no overheating. So that’s good.)
