This is a companion topic for our recent blog post on blog.unmanned.tech
In our latest blog post, Painless360 takes us on a delightful jaunt through the murky waters of telemetry inaccuracies in EdgeTX. If your battery voltage is telling porkies, it might be time to give the telemetry sensor a good talking-to. The key takeaway? Always fix the problem at the flight controller first—less fuss, more accuracy, and you won’t inadvertently mask a dodgy sensor with a band-aid solution.
For those brave enough to dive into the inner workings of EdgeTX, we break down the telemetry sensor edit screen. Understand what you’re playing with: name, type, ID, and yes, even the rather cheeky ratio and offset fields. We also give you a step-by-step guide to sorting out that RXBAT reading that’s doing its best impression of a flat battery when you know it’s still got some juice.
Remember, calibrating to just one battery state is like trusting a magician who only shows you the trick once; you’ll want to check across the full spectrum of your battery levels. The maths involved isn’t too taxing, especially if you keep that “back of a fag packet” approach in mind, so don’t shy away from a bit of algebra.
In short, while editing telemetry can sometimes feel like rearranging deck chairs on the Titanic, it’s a valuable skill when necessary. It might be best to do your corrections on the flight controller—but if you find yourself in EdgeTX, use both offset and ratio judiciously, test thoroughly, and don’t forget to apply the filter to keep things neat and tidy.
