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.

To see it, click on “RADIOS” on the menu bar above.

If you have reached a point that you feel you want to check or adjust the maximum throw of your rudder blade from side to side that your transmitter generates, what is a way to do it??

I tried to simply find the answer to “what is the optimum maximum rudder angle?”…. it’s not as simple as you’d think !!

Beginner’s Guide to Winches and Drums

Leave a reply

I was going to start a fresh item on Winches and Drums, but have lacked the time to get on with it.

Instead, take a look at this page (link below) on Lester Gilbert’s fabulous IOM website. It;s possibly a little dated now, but I found it very good for :-

1/ Understanding more about how the basics of how the transmitter joystick is actually talking to the winch.

2/ Get the basics of a plain drum, spiral drum designs and drum sizes versus winch power

3/ The spiral drum is really clever in its intent, but realise that electronics might have taken over this role. Now we have Throttle-curve on our transmitters plus the latest Stinger winches have this function onboard in their software.

4/ Good simple explanation, with diagrams, of Open Loop and Closed Loop sheeting systems – which I found great.
