FrSky Q-X7 - an F3F-ready transmitter for £100!

The FrSky Q-X7 may not have the looks - or the price tag - of a premium radio, but don't be fooled - it's a remarkably capable device which is fully capable of driving an F3F model to the extremes. In this post I'll highlight key aspects of this transmitter, and explain why it offers such ground breaking value.

E-Soar Plus 3.0

E-Soar Plus, my template for sport and F5J, has proved popular with F5J flyers, and version 3.0 adds some extra flexibility and refinement. The main enhancement is a choice of three arming methods, and in this post I'll describe the background to this and other 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. The mix has been part of my Needle 115 setup for a couple of years now.

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, that is. Unfortunately my unit arrived with a gimbal which was stubbornly 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. This offered a  perfect opportunity to inspect the internal layout of the transmitter. Was it all good news? Read on...
