E-Soar Plus 3.0

Two years have now passed since version 1 of E-Soar Plus, my OpenTx template for sport and F5J electrics. Since then it's undergone a number of improvements. In the meantime, OpenTx has itself been enhanced, so we can do things now that couldn't be done before - in particular OpenTx 2.2 has double the number of logical switches (64) as previous versions. Taking advantage of this I've recently released E-Soar Plus v3.0

The new version offers a choice of motor arming methods, and other enhancements. In this post I'll provide some of the background behind the changes.

Advanced snapflap mixing with OpenTx and Lua

In this post, I'll describe a snapflap mix with the emphasis on 'trimmability'. It offers full control over the snapflap curve, with all adjustments via dedicated controls. In addition, alerts are sounded when snapflap exceeds user-defined thresholds. I developed it for my Needle 115, and have been using and refining it over the last couple of years.

A simple way to measure stick tension

My trusty Taranis X9D has finally suffered its first major issue in four years - a broken spring on the elevator gimbal. And yes, it failed in flight! Fortunately I was able to land the model safely.

Horus X10 preview - an upgrade for your X9D?

The Horus X10 is the second 'quality' radio to be released by FrSky. The new radio bridges the gap between the venerable Taranis X9D and the premium Horus X12S. Will it be good enough to persuade X9D users to upgrade? Will X12 users all suddenly want to downgrade? Let's indulge in a bit of informed speculation! [20 Nov 2017: section on charging updated].

Checking out your new FrSky transmitter

Over the years I've set up a variety of transmitters for myself and friends and as a result I've got to know what to look for and what to check out with new kit. So in this post, I list a few tips, including an effective method for checking the range.

Getting inside the Horus

The Horus is a sweet piece of kit - when it's fully operational. Unfortunately my own unit arrived with a gimbal that was double-centring. To FrSky's credit, it didn't take long to receive a replacement gimbal, and today I cracked open the transmitter to install it. It also offered an opportunity to inspect the Horus internals. Was it all good news? Read on...

Preparing your setups for OpenTx 2.2 RC10

The OpenTx developers have been making great progress with 2.2. The latest build is able to open .eepes created in OpenTx 2.1, and convert them to OpenTx 2.2 format. Even better, they can be re-targeted to the Horus - great news for those wishing to migrate their setups to the new transmitter.
