Time for a refresh: Mike's OpenTX/EdgeTX Clinic

My OpenTX Clinic website is no more. Long live OpenTX/EdgeTX Clinic

A bit of background: I created OpenTX Clinic about ten years ago, round the time OpenTX was launched. Since then the site has expanded steadily, with sailplane templates, Lua scripts, tips and code snippets.

An introduction to ELRS - plus how to deal with Channel 5

If you haven’t heard of ELRS, then you soon will - it’s an interesting long-range protocol which is finally coming of age. 

ELRS was originally designed for use with flight controllers. However, thanks to receivers like the RadioMaster ER series, ELRS is now a great option for line-of-sight flying - including F5X and F3X sailplanes. 

So what exactly is ELRS, and what do you need to get started?  Read on, while I take you on a tour!

RadioMaster Pocket: a fine little EdgeTX / ELRS / MPM transmitter!

What's this dinky transmitter on my desk? It's the Pocket - the smallest in a series of compact transmitters from RadioMaster. It comes with a choice of modules (ELRS or CC2500 MPM) and is very keenly priced. Oh, and it's stored in a little pouch!

Spoiler alert: the Pocket may cost ~£65, yet is more than a match for £1000+ radios. I know because I've flown an F3F model with it, with all the mixer bells and whistles. Crazy times!

Read on and find out if the Pocket is for you...

Review of RadioMaster ER6G, ER6GV, ER8G and ER8GV receivers for ELRS

RadioMaster have just released a bunch of ELRS receivers specially for gliders and electric models.  These  are notable for being some of the first ELRS receivers to have servo connectors integrated on the main board. 

I've been having fun evaluating these receivers, including flight testing them in DLG and F3F models. In this review, you'll find detailed descriptions, with example configurations, best practice, and tips for ALT telemetry. 

Let's take a closer look!

RadioMaster Zorro review: pushing the boundaries

RadioMaster have a new baby transmitter. Yes, it's the Zorro! You'll probably already know that it's packed with features, supports OpenTX and EdgeTX, and comes with a choice of Multiprotocol or ELRS modules.

However while most of the Zorro reviews focus on its use with drones, this review takes a different approach - it's geared towards pilots of sailplanes, DLG and electric gliders. If that sounds like you, then read on!

Supertrim - a better interface for trimming crow brakes

In this article, I describe an improved user interface for trimming out crow brakes. It uses the standard features of OpenTX - no Lua script is required.

The best font for your CAA Operator ID

If there's one aspect of the UK drone laws which is particularly grating, it's the requirement to display your operator id on every model. To add insult to injury, it's now a whopping 19 characters!

There is something we can do though: make the actual label as small as possible...
