How Much Radio Range Do We Need Anyway??

How far away can we see race marks, start line situations and sail numbers? Not far.

I’ve just had a bit of a shock though. You may remember that I have a horizontal, dead straight, line-of-sight, transmitter range test based in the street where I live.

I recently put Radiomaster and Futaba through the exact same test and basically got a radio range of around 200 metres for both of them. Blimey.

Radiomaster just a tad more maybe, but I ran out of straight street and had to go round the corner. That is way more than we need in radio sailing.. I can hardly walk THAT far.

You can read my recent range comparison for Radiomaster and Futaba here:-

Tests conducted by RC Flyers in the USA suggested that Spektrum only reached maybe a quarter to half the distance of Radiomaster/ELRS. I was curious to test my DX8e against it. I am just starting to prepare the Datchet Radio Sailors’ online manual for Spektrum. I thought I’d put my own lovely Spektrum DX8/AR620 through the same range test, using the same boat…. before I start the programming and manual writing.

I’m a bit stunned. At first, I thought it must be low battery power, and so changed all the batteries for fresh ones. Same result. So my next thought,… after swearing,… was “faulty transmitter”…. (you might say!!) …. but I’ve had this particular DX8 range tested and a fix applied at the Spektrum UK distributor, and it passed their tests just fine after that.

You might be thinking that it was caused by the smart but tiny, and wire free, ceramic antenna of the AR620 receiver. Maybe. Lovely kit though.

But the Radiomaster in this test also used a ceramic antenna in its ERC3i – even more weeny and more tiny that is. It’s so small, you’d be inclined to try and wipe it off the hull in case it’s a speck of mud.

The AR620 is about twice the physical size of the ER3Ci. When I get the time, I’ll re-test the Futabas without the SailsEtc antenna frame … just dangling wires in the pot … to be disproved, but I personally suspect the antenna frame (called “aerial holder” at SailsEtc’s website) is a big factor in this test.

I’m reluctant to trot down to TJD Models and buy a wire-antenna Spektrum receiver, as I’ve seen an official Spektrum video claiming that the ceramic antenna has better range.

But – well, how much do we need in radio sailing? I’d personally have difficulty racing 75 metres away – it’s surprising how far that is. I know a number of radio sailors who simply adore their Spektrums… but for myself, I’m still surprised by this test result. The guys at Datchet want me to test a FlySky over the same street. I’ll do that as soon as it’s practical – I no longer have a FlySky here, but I know where to get a loaner.

Craig’s Proteus Mainsheet Joystick Setup

Did you see Craig’s post on the Proteus Facebook Group regarding the way he has set up his IOM mainsheet joystick??

You can probably successfully click on this link below to see it

In fact, a couple of the Datchet guys are working more with this idea now. It requires 101% concentration, but you can see the attraction.

Craig has it set up on his Spektrum. To do it similarly on your Radiomaster or Futaba transmitter is another variation on the “Advanced Mainsheet Management” sections of our online Radiomaster/Futaba radio sailing manuals.

It’s Winter – Let’s Talk… Toolboxes!!

You have to watch the prices in Screwfix like a hawk !! – sometimes they have the most amazing offers. I was in there this morning and saw this ….

Did you notice in small print, it’s 2 for the price of 1…..!!! £13.50 per tool box.

If you’re new to radio sailing, and most probably have come from another branch of the sport such as dinghy or keelboat racing, you’ll try bringing your old toolbox and tools with you. I did. It was quickly a hopeless venture 🙂

In the radio sailing part of the sport, we have special tool and toolbox requirements.

  • large variety of bits and pieces, usually smaller sizes
  • unexpected calls on the toolbox for a huge spectrum of reasons, usually in a hurry, often in the rain
  • tools/parts smaller and often more delicate.
  • no rummaging, a need for speed, a protected environment for delicate things

Out goes the big keelboat toolbox! No rummaging under the spanners plus we need to see where all the bits are at a glance.

RW and Rj got stuck into this subject last winter, but neglected to publish the results. We tried for a short period those toolboxes with cantilevered fold out trays. Such boxes around here are of appalling quality to be honest, plus we didn’t want to swing out the cantilever trays in the rain and everything gets wet all at once.

Conclusion:-

  • lots of nice small sealed trays is a good thing
  • Reconfigurable trays is an excellent idea
  • clear windows so you can see what is stored where in about 1 second flat, all in the car boot !
  • weatherproof and probably not metal construction
  • solid, sturdy, high quality but not costing the earth

We ended up testing two almost identical products, same dimensions almost. In the trade they seem to be called “Organisers” not “Toolboxes”. Both brands feature little locks on the sides to enable you to stack one on top of another securely – might be a consideration in your car boot….

In the end, RW and RJ concluded that the Dewalt model (left of photo) is slightly better. Note the long side compartments for screwdrivers, pens etc. Note also that the Stanley model (right of photo) places the handle grip in an area, where in the Dewalt you can remove the storage compartments to get your 12 inch rule, surgical tweezers and long things in.

This is the Screwfix Link to the Dewalt offer of the month.

When we did our trials, the Dewalt was £40 and the Stanley was £20. RJ and RW quickly agreed that the Dewalt was best for radio sailing and, I think, despite the extra price RW has four of them!! Really sturdy, high quality, each very visible compartment is sealed when. the lid is down.

For myself, I’m using both and find I can carry tools and spares for 3 classes in two of these boxes. So I’d say £29 for the Dewalt is great – but that’s until I saw £13.50 for the Stanley.

What do you think?? A good opportunity to sort out your tools and spares?

Screwfix tends to have short lived offers. Move fast if you want a couple.
