FR Sky Transmitters…!!

I managed to get my hands on one of these a couple of days ago. From the airplane and gliding world, the FrSky Tandem X20….. Bit of a wow. It was interesting to see what they use over in flying.

They cost about double (450GBPs) what radio sailors would think of as “pricey”, but can you tell the difference?

Amazingly – a resounding “yes”…. the feel was a huge step up from what we are used to. The body was a lot more solid (alloy maybe) and interestingly weighed about 900g so a bit heavier than common radio sailing transmitters. It felt very good in my size/shape hands. The “Apple” of transmitters maybe.

Gimballs (“Hall gimbals”) very smooth and more central on the console which somehow gave a nice balance (nearer centre of gravity perhaps) while you used it. Thinking about it more, if you move the screen to the top of the unit (most of our transmitters have the screen at the bottom), you can then move the gimbals down lower on the console itself.

Another thing I noticed was that the gimbals can be rotated slightly for those in search of more comfort over longer periods. Somehow, the whole thing looked more showerproof too. Really tightly fitted together.

When we decided to write the radio sailing manual for Radiomaster transmitters, I came across FrSky because the previous range FrSky along with Radiomaster use the same OpenTX software. FrSky seem to have abandoned that OpenTX strategy now as it was holding them back. They have done their own modern looking operating software called EthOS. That’s amazing too – it’s like having a full iPhone aboard, …all icons, colour and sexiness. Lots of preloaded configurations for power mixing and the like.

I might have misunderstood, but the owner said you could send updates (like custom model configurations) to it “over the air”…. so he can swap configurations with friends very easily.

The owner of the unit that I tried was a Competition Gliding fan. I asked what he used previously, and interestingly he had a Spektrum DX6E – which of course is very common in sailing.

Way over-configured for the needs of radiosailing, but it was interesting to see what £450 would buy you.

Beginners Guide to Diagnosing Under-Deck Problems – Electrical/Radio/Winch/Servo….!!

I had a little outage last Marblehead Sunday. The boat slipped into Failsafe mode and drifted quietly off toward the Royal Castle of Windsor!!

The Commodore leapt into RIB duty mode and helped me get it back, no problem! Useful to take a lifter with you! As soon as racing finished, in classic Datchet manner… everyone gathered around, tool boxes came out, to get my fault diagnosed.

It was pretty educational and a great learning to see them go about it. We quite quickly figured all the electrics and radio were OK and identified the winch as a possible failure point. It was great to see them checking out the transmitter, receiver, battery, cabling etc.

All this learning was a delight. So as not to lose it, I have documented the diagnostic and repair process here. If you find yourself in a similar position, it may be helpful. Click below to download.

RMG Winch and Drum Setup on a One Metre (K2)

This is all somewhat daunting at first, especially for the newcomer.

However, this a is a great little video on RMG setup in a K2. The principles are clear and if you watch carefully, there are great little incidental learnings along the way.
