2D Mainsheet Control – a Key Difference with Radiomaster…!!

Leave a reply

When we started the advanced transmitter programming project, I was generally of the opinion that you could program more features on Radiomaster than on the other brands… you can get your fingers in closer to the code….

Then the day before the IOM Worlds, our very own top Kiwi (Dave L !!), brought me a question about 2D Mainsheet control on his Radiomaster Boxer.

David wanted asymmetric mainsheet adjustments for left and right joystick moves. For the sake of argument, he wanted the mainsheet coming in 1cm on a left move of the stick, but to go out 2cm on a right move of the joystick. Nice – and I was confident we could do it.

… and there we were just 24 hours before the first start and I couldn’t get his Radiomaster doing it though. Very cross I was – AND confused… as I was sure I had that idea working at one point.

(You can see a very nice little YouTube from Craig showing this working on his Spektrum.)

Looking back at my notes it looks like, sure enough, I have done the code for this idea on Futaba and Spektrum… but not for Radiomaster. (see our Futaba and Spektrum online manuals bu clicking on RADIOS in the menu bar above)

A BIG surprise to me. So far this morning I still haven’t got this working on Radiomaster for David.

If you have managed to do it on your Boxer or TXnn, could you write in with the answer and we’ll publish it?? Contact us via the “Contact” page of this website.

Radio Manuals – PDF Downloads or Online Websites…??

Leave a reply

If you use any of our transmitter manuals for radio sailors, you’ll know that we did all our basic manuals (and one of our advanced manuals) as pdf downloads. Very popular they were too. (about 3650 or more downloads as I write in July 2026).

Then we did our more advanced featured manuals for Radiomaster/Futaba/Spektrum…. they have been popular, but nothing like the usage yet as the pdf download manuals.

So as a little test we decided to offer the Radiomaster Advanced manual as both a PDF download AND its own website.

Astonishment – the pdf download is already twice as popular as the website …. 650 downloads already.

OK … give us some time and rainy days, and we might put the work in to make the Futaba and Spektrum Advanced manuals available as pdf downloads as well.

If you have strong opinions, just email them in to the website via the contacts page.

A Small Piece of IOM Worlds Legacy : Advanced Radio Sailing Transmitter Manuals……!!

Leave a reply

A lot of you clearly know about our downloadable collection of beginner radio sailors’ transmitter manuals. There have been around 2000 downloads now – we have FlySky, Futaba, Spektrum and Radiomaster in there. By the way, the Radiomaster manual on this list is by far the most popular. Given that we estimate there are only 19,000 radio sailors in the world (says AI !!), we think that 2000 download number is pretty interesting.

During the build up to the IOM Worlds, some mind boggling GBR talent put its mind to work to see if advanced features could be found on transmitters that would give the competitors a little competitive edge. The idea became to make three different radio sailing transmitter websites (Radiomaster, Futaba, Spektrum) and charge readers a nominal amount to subscribe to generate some income for the IOM Worlds.

A good idea… but we just ran out of runway and had a thousand other pieces of prep to complete. So we never got around to the monetised subscription idea. We’ve still got the manuals websites though.

For the basic radio sailors’ transmitter manuals, the easiest way to find them is to find the list of “Categories” on this website and select “Transmitter Manuals”. Alternatively use the website’s “Search” bar.

As to the three ‘advanced radio sailing transmitter’ websites, they are now online and available for free. To find them, just click on “RADIOS” on the menu bar of this website and you should find the three of them available there.
