Well done Adrian.
Incidentally, you might like to look at the SM Modelbau UnisensE sensor. This provides from one small sensor package: V, A, height, Vario, capacity, rpm etc. The sensor can be set up to speak to most Txs including Futaba. I've used it with my JR and now with my JETI. You will find an English language translation here. SMB also do a range of other sensors but I've never used any other than the UnisensE and I can thoroughly recommend it. For the price, it takes some beating and, provided you buy the USB interface, you can both set up and update the firmware using the freely downloadable software.

Phew, thank goodness for that. Another storm in a tea cup! We do like our storms though!

Only managed to get out to my other club field. When I arrived, the temp was 2C snd when I left 2 hrs later in the gloom at 4.15 it was 1C. The good news was the wind was almost non existent which was ideal for checking the Anthem's trim with it's new (well second hand) Jeti DS24. Like Kev's, our windsock was also broken.
The calm conditions allowed me to check the vertical downline mix and the 2 mixes for ensuring a knife edge and KE loop using rudder and motor only. 2 flights each with 2 intermediate landings to tweak the mixes (I suppose that makes 6 flights!) left me with 2 packs to practise my current competition schedule with a fully trimmed F3A machine. Bliss.
The photo was taken 2 days ago but I forgot to post it!

I have a Bucker Jungmann just like that! It has an OS91 FS Pump and flies very realistically with that amount of power.

Decided to open my 2025 account despite the temp of 3C. Got in 3 flights before the cold got at me and the light faded.
This was my 2nd flying session since I moved radios from JR to Jeti. I had fitted stronger stick springs but had turned the stick tension too high for the first session so turned the adjusters right down and that seems spot on now. Still a bit more trimming needed for the rudder/aileron KE mix but I was too cold to think straight by then.

I took delivery of a Jeti DS24 and a few other bits and pieces on 18th Dec. I've had recourse to a club mate who has a DC24, a tray version, and spent a couple of hours with him trying to get my mind out of JR XG11 way of programming into the Jeti way. I also watched a few of Harry Curzon's excellent videos that are now making a bit more sense as I can actually follow him now! Suffice to say, that I finally decided that I had fully emulated the program for my F3A Anthem in the DS24 this morning. So, spurred on by the strange phenomenon of a blue sky and Sun, I went flying in the afternoon.
Pleased to say that despite the gusty conditions at my second flying site, I got in 4 flights. 2 were trimming and testing and 2 were of the P25 schedule. Interestingly, I'd fitted strong springs to the Tx sticks and wound them up even more. Turned out that with these very stiff sticks I found it difficult to fly accurately! So, when I got home, I undid the adjusters so that the stick tension felt about the same as my XG11. There's something I didn't expect.
There is still a great deal to learn about this Jeti DS24 but this will keep me going till I can no longer fly!

My goodnesz, this thread has been wknderfully eclectic. First, it wasn't about Royal Mail, as has been pointed out already, then it flirted with Brexit, now its on to bank charges for international transactions.
How zbout the cost of milk next?

Correction: Looking again at our club rules and also the BMFA rules, they both state that if your transmitter has a "failsafe" system available, then it should be used. The action being to "prevent the aircraft flying away in the event of loss of signal". Not to 'kill the throttle' as I stated in one of my previous posts.
Thanks to you all for your very useful info.
My understanding is that it is more than "should" it is a mandatory specifically to prevent flyaways.

There's a fine line between a challenge and idiocy Adrian! I had one moment when idiocy almost won! Still provided you've thought through everything before hand you are better prepared.

Having arranged to fly at my wide open site this morning, my partner felt the wind was too great. So, after agreeing, I took a walk outside and decided that, while I couldn't fly at my wide open space field, I'd try the one with big trees on 3 sides. As I walked out with the aircraft for the first flight, the wind got up even more!. Still, a litter voice said, "you'll be OK, just don't panic!".
So, got 3 flights of my schedule flown. The first time that I had flown in such a strong wind for a very long time! Inevitably, I tended to be pushed downwind on the schedule as I just wasn't making enough allowance for the wind, which , of course, was much stronger higher up. So sign of the "constant flight speed" required by the FAI! I had to overshoot on my 2nd landing as a big gust came through just then, but pleased to say that all the arrivals were gentle - the result of not panicking and letting the aircraft sit down when it wanted to. The 2nd take off was quite alarming though. Again, just as I was getting airborne a big gust struck and rolled the aircraft to about 60 deg to the right. This did catch me by surprise and led to a bit of PIO as I sorted myself out.
Sadly, all 3 Tx batteries, despite being charged as fully as they would take - 6.9 v as opposed to the more usual 7.1 v ( its a 2 cell LIFe pack). I shall have to investigate as this is the first time they have misbehaved. It wasn't that cold either - around 11 C. So, discretion intervened and I packed up and went home. Pity as I was beginning to get the shapes right in the strong wind! Needless to say, I was the only idiot flying!

When we were sailing we were required to have insurance (£1 million 30 years ago - probably a lot more now) and the hosts at open meetings used to check insurance before we were allowed to race. Then the clubs stopped checking and just specified it as a requirement which was the sole responsibility of the sailor. The reason was to avoid a mistake and need to accept responsibility for a possible misreading of (say) the date on the insurance certificate. If the onus is on the club member it absolves the club. Seems a sensible thing to do IMO.
The ANO puts the responsibility on the pilot at all times. It is the pilots responsibility..........etc

IMHO, I think it's the fear of showing yourself up when flying in front of a lot of people.
I'm, ahem, 74 now but still fly competition aerobatics. Last year, I managed to come last in every competition I flew in. However, it has spurred me on to try and find out what are the errors I'm making and how do I put them right. This does require a lot of practice including tweaking aircraft set up and that seems to be something most club pilots seem to find total anathema! The atmosphere at all the aerobatic competitions I've ever attended has been wonderful. People are always willing to help and I've never seem any prima donna behaviour or any "super competitive" behaviour. The super competitive comes from practicing a lot so that in competition you are as well prepared as you can be. This, of course, means that you have taken the time to trim out your model properly rather than just putting in a few trim pushes till the aircraft flies sort of straight. I've lost count of the times that someone has handed me a model to check out that was trimmed but when I let go of the sticks clearly wasn't! So, are we confusing just having fun with putting up with a lot of low skills that we can't be bothered to improve upon? Could be something in-between of course.
Just my observations.

Thank you gents, 35% it is then. It takes forever using the discharge on a charger. I am using 12v auto bulbs to initiate the discharge, with a check on the charger to finish.

The other thing to do is to charge your packs after flying to storage level. That will reduce the time for the full charge when you choose to do that. That way, you won't end up flattening a pack because you were distracted at a critical moment! If you do end up with the pack a little below the minimum of 3 v/cell and your charger won't charge them, try selecting NiMh and charging at 50 mA until the lowest voltage cell has gone above 3 v. Then switch to normal LiPo charging. If that doesn't work, then the pack will have to be replaced. I have recovered a pack this way and it went on to give good service.

Most chargers have a storage setting. I generally land with around 3.7 V/cell remaining and leave them like that till I next charge them.

Having seen the way some people fly, I'm not surprised!

It was posted on a French news program regularly upside down.
Can't tell the difference with the French flag whether it's the right or wrong way up so I suppose they think all flags can be flown either way up! I suppose the more observant ones notice when the colours are horizontal or have some obviously asymmetric design.

If you have just taken up flying then it will be best to join a club. Use the Club Finder on the BMFA website to find one close to you. If there is more than one then visit each to find the one that suits you best.
-
Did you join through a BMFA Affiliated Club or on your own? Either way, you should have had an email from the BMFA inviting you to rejoin brfore the end of December. Check your Span folder.if you didn't. In any event, just go onto the BMFA websire and click on the big blue button titled "Join us or Renew your membership".

what do you think of a Spitfire as a trainer ?😃
Completely daft! Especially with a 33 cc engine! Still, I suppose it will be alright until you get to the landing bit!

Weather forecast software
in All Things Model Flying
Posted
XCWeather for me. Of all the apps I've tried, this is the most accurate but only looking 1 day ahead. We have such difficult weather to forecast that looking 7 days ahead is just the same as gambling!
