Radiomaster : Advanced Transmitter Guide for Radio Sailors….!!

Leave a reply

As we write, (14 January 2026) our Radio Sailing Beginners Guides to Transmitters have been downloaded globally 1,600 times. 958 of those downloads were for Radiomaster.

Today we have launched our Advanced Radio Sailors’ User Manual for Radiomaster Transmitters. It covers all the very sexy features that many of you have been waiting for.

It has taken time from several Datchet Members to pull all this together.

Instead of publishing a pdf download manual as we have previously, this time we have given the transmitter its own website. Now you can use it from the side of the lake reading from your phone!!

If you look at the website’s menu bar, you can also download our previous Radio Sailing Beginner’s Guides to Flysky, Futaba, and Spektrum (download from USA). We have also included our advanced Futaba User guide which covers the same advanced Radio Sailing features as the new website. All our Transmitter manuals in one, easy-to-find place.

Marblehead Games – Littleton

Leave a reply

Eight of us took our Marbleheads over to Littleton (Guildford MYC’s new home) today to compete in the Mermaid Trophy and part of the Marblehead Games series.

It was shorts weather last week, and polar weather today !! We were on A rigs in the main.

The huge proportion of the fleet were sailing F6’s – a very nice feeling for PH and GH, to see the result of all their years of hard work making an impact.

Two of our advanced Radiomaster transmitter projects were also in test today – looking very good! (More on this before the year is out) PH’s new TX15 was looking very smart showing off its multicolour gimbal illumination in the half light of the afternoon! Very Christmasy !!

The event organisers made an interesting claim – that this Games Series is the longest continually running Marblehead event in the country…. it’s been running since 1979 even through covid and lock down! Pretty good !!

It was a nice size fleet of around 12 or 13 competitors. Final results will be with us shortly. Hotly contested at the top! NB was beaten into second place by just 2 points, and HM came 3rd – both of them with a good number of race wins!

Radiomaster Ratchet on Throttle/Winch Joystick..!!

Leave a reply

Are you a mainsheet ratchet fan? I admit that I am, but at our club opinion is pretty passionately divided !!

In my transmitter collection, the Futabas have a ratchet as standard and the Spektrums have a ratchet you can switch on and off from outside the front cover (nice!).

However, I always thought that Radiomaster has no ratchet capability. It turns out that is probably true for my Radiomaster Pocket,… but if you have a Radiomaster with AG01 or AG02 CNC machined gimbals (eg Boxer or TX15 ) there is a ratchet in there. You do have to go inside to switch it on/off or adjust it though.

Ratchet and gimbal tension are both screw adjustable on a simple (crude!) pair of spring friction levers inside. You might also need a little “hack” if you find your ratchet adjustment spring sticks on the adjustment screw thread.

This little video (below) is a tour of the whole AG01 Gimbal joystick. (worth watching if you have a Radiomaster). If you skip forward to minute 4’15” you will arrive at the video section about adjusting the ratchet and gimbal tension – with the “hack” !!
