Beginners Guide : Transmitter Snugs…

Radio Sailors really can put a lot of thought into transmitter snugs. This brilliant one above, used by our Champion DB, looks like it has an exit for the transmitter aerial… Interesting!!

This second example looks totally amazing, but when you realise it is being used by one of our most ‘decorated’ champion radio sailors it gets your mind whirling as to what thinking is being poured in here.(!)

If you’re in a warm climate and don’t use a transmitter snug, consider that one of the most amazing and competitive sailors in UK likes to keep his fingers and switches out of sight, so that competitors can’t get to see what is going on in there. All you hear is a “click-click”. I love it. Fabulous gamesmanship. (See the story of Rodney Pattisson’s Centreboard aileron trim tab on Superdocious… allegedly simply done to distract competition!)

(Note snazzy BG logo sneaking in at the top of the photo to remind you that at least two of the greatest minds in sailing have thought about the design of this snug!)

Do you live somewhere with a climate where the idea of a transmitter snug doesn’t really apply?? Well, here in UK, we use them a lot !!

I saw Rob V with one of the new Rooster Snugs from Steve Cockerill (see above). Very nice it looked too. They make some really nice sailing products at Rooster, so this bodes well !!

There happens to be three different makes of snug in the workshop at the moment. Want to see the differences of design?? Read on….

Since I started radio sailing, I’ve only used a Catsails snug (see above). I borrowed one with a loan boat for a year, then simply stuck with the same. I like it. You’ll see lots of them around – a good well made, well designed, sturdy product.

I also have a snug from Wtotoy which I got from SailboatRC with the IOM. I hear that SailboatRC might be about to produce their own design – watch out for that. To be honest, I don’t take to the Wtotoy at all, but it does teach a lot about what sets Catsails and Rooster apart.

When you go to choose your next snug, here are some things to look out for:-

Transmitter Considerations – Access and Security

The Rooster and Catsails snugs both have stout strong zippers on the body-side of the snug, compared to a velcro closure away from the body on the Wtotoy snug (see photos above). Thinking through this, my guess is that you would all think the access from body side with a strong zipper was the most secure.

Rooster additionally put this little velcro storage loop inside the snug to secure your transmitter – but to what? Good for Futaba and Flysky transmitters (use the handle) but I’m less sure how to use it best on the Radiomaster Pocket or the Spektrum (slightly more awkward handle to access). Would I forget to do it after a few outings? Better to have it than not though.

Size – Big Hands, Large Transmitters?

(Top photo – Rooster on top of Catsails, bottom photo Rooster on top of Wtotoy)

I thought I had big hands until we ran our item comparing transmitters.

Most probably you’d say that your hands fit all three, but in reality these three feel very different in internal size. I have feeling that the Catsails snug is the most capacious (see photo above), but it might be deceptive. One of them would suit you better, for sure. The Rooster design comes higher up your wrists which is another consideration entirely.

By far the most capacious of the three is the Wtotoy, and the Rooster and Catsails do tend to feel different inside. The Rooster gives a totally different impression as it is designed more to come up your wrists like a pair of gloves. The “sleeve” on the Rooster compared to Catsails is quite pronounced. (see photo below)

If you are a large hands Spektrum user (largest transmitter we have measured) , it’s a double challenge – you are going to want to try both snugs before deciding. Don’t forget your switch clearance! (see our other article)

Neckstraps and You

Let’s start with the Wtotoy and dismiss this. It has no neck strap capability.

The Rooster and Catsails snugs both have an external eye, and the Rooster comes with its own neck strap and quick release buckle.

Both Rooster and Catsails brands have put the securing eye behind the viewing window, so I would guess that the centre of gravity will tilt both away from you if you take your hands off. It’ll vary a lot by transmitter (see our comparison article) weight and centre of balance, but you might want to check this out before you decide.

Weather – Warm or Dry or Both??

In Uk, we would be thinking both about keeping our transmitters dry and perhaps also keeping our hands warm. At our Club, we prefer to sail year round (maximise subscription value!) so both are a prime consideration for us. All three snugs here are made of very waterproof material, so no worries. The Wtotoy additionally has velcro adjusters at the wrists (is this a two person job?) and the Rooster is designed more like a glove to come up the wrist to improve closure.

As regards warmth, you are going to be happy with these, but consider if they would get too hot in summer. I’d guess straight away that the Wtotoy would be warmest and the Catsails the coolest, Rooster in between.

The Wtotoy has a furry lining which is not to my own preference

The Rooster and Catsails snugs both have that clever aqua fleece type of lined material which is robust and (to me) feels great.

I’ll test the Rooster and Catsails next winter to see what their thermal performance is like, but I’d gu ess by design (sleeves effect) the Rooster will be warmest and the Catsails the coolest. What would you prefer?? I confess, I’m not sure yet. When it’s properly cold, do you wear gloves too?

I’ll trial both the Rooster and Catsails snugs over the next year and try and form some conclusions then.

Receivers and Confined Spaces…. Part 2 !!

A few days ago we wrote about the impact of RC Flying on receivers and how we might think about them in Radio Saling’s confined spaces. First a look at some of our choices:-

This is the dinky little Radiomaster 3 channel ELRS receiver, much favoured by our Commodore, Phil. Seriously compact little thing… you might be inclined to mount it eg on velcro on the back of the unit as photographed. So the important thing in this discussion is that the connecting leads (as you can see in the photo) will stick out at right angles to this surface.

Next one is the Spectrum AR620 much favoured by Craig and Rohan. Six channels and in reality hardly any larger than the ELRS above. But note : you probably will have you velcro pad at the bottom face in the photo above, and consequently your sockets will stick out parallel to the mounting surface and not at right angles. Great for flying wing planes to permit mounting inside the wing (see first article). Really the unit is so diminutive, in radio sailing it’s no issue where you put it.

Before I illustrate photos of the two current Futaba receivers that are most relevant, I may ask if you know the depth of your receiver “pot”? As I recall, the new Proteus design is “pot-less” which is interesting. In the two boats I have here, the SailboatRC pot is 105mm deep and the SailsEtc pot in my Marblehead is 80mm deep. Keep that in mind for a minute.

Two of the current common Futaba receivers are these :-

This is the six channel R3006SB receiver – note the sockets are at right angles to the mounting surface.

This is the 8 channel R3008SB receiver – note that the sockets are in-line with the mounting surface. So by the time you wiggle your two or three plugs in here, you end up with quite a long unit.

This is the R3008SB mounted in the 105mm deep SailboatRC Pot. Plenty of space and the factory have chosen the put the electrical connector end lowest in the boat. Interesting. It would be possible to install the same receiver inside the 80mm deep pot – just about… but unless you invert it, the plugs are going to be quite close to a bilge water threat. I have been wondering of plugging in vertically like under a little umbrella is actually good for repelling water…. I’ve no idea !!

So if you are using a normal SailsEtc pot, you might prefer to consider the six channel R3006SB (with plugs at right angles) and secure that in the pot as high up as you can… quite probably with plugs at the top so they are as far away from a bilge water threat as possible. Here is that receiver installed in Nigel’s F6 – can you see what I mean??

I have been considering acquiring another Futaba Transmitter soon – prices are keen at the moment. However, my model shop in common with many now sells you a “Combi” pack which obliges you to take the transmitter with an 8 channel R3008SB receiver. It comes directly from distributor stock, not theirs. I really want to buy from my local man, but it looks like I might have to get a transmitter-only price from somewhere and buy a six channel R3006SB receiver separately alongside. So far (at the time of writing – March 2025) I have managed to find “Inwood Models” who sell from their own stock (keen price) and do list the receiver components separately. Might be the answer….

ELRS … So The Commodore Was Correct ….!!

Our Commodore, Phil H, has long been very keen on the performance of his Radiomaster-ELRS receiver… “never dropped a signal”, he says.

Can you read that table above ? – it’s a tad blurry, but I think you can. These are ground-to- ground test results of some major transmitter-receiver brands aimed at the Radio Flying community, …who are interested in distances measured in kilometres..

The test might also typically be using receivers with a lot more channels than we use in sailing. The test person gets more into the transmitters, but receiver capability will be a big part of the equation.

You have to keep a sense of proportion – flyers seem to worry about ranges measured in kilometres, whereas, honestly, if our boats are 100m away I panic about whether I’ll hit a mark…. or not be able to tell which one of the pack is “me” !!

No need for us to be extremely picky about range and distance, but it’s all relative….

Sure enough, Phil – the major conclusion of the test is that ELRS is basically in a class of its own. FrSky Tandem was quite close (see our recent website article), but we don’t see many of those. You can see why the tests were controversial, but essentially they left the receivers in one spot then drove the transmitters into the distance (flattish undulating terrain) until they dropped signal. I think at one point they drive over a hill and see if the signal is regained the other side.

When you are dealing with radio sailing distances of 100 metres or so, if you have signal drops you probably need to check out other parts of the system. … Interesting though…. The full link of this 2024 video is given below – it’s long and much of it somewhat heavy going. If you skip forward to around the 1’17”, the summary and results start around there.
