I was late myself so Tom arrived about the same time but he hadn't been able to get the Trainer model prepared so I asked if he could just look over my shoulder while I tried to fly the two I'd brought;
The Plastic Cub
I got it off the ground into the air & turned it anti-clockwise but as it came round & faced the wind it started to carry it away. I had two or three attempts but couldn't get it to come back. By this time I wasn't sure whether it was behind or in front of some LV power lines in the next field so I handed it over to Tom who concentrated on getting it on the ground. By the time he had done that I couldn't see it but was told it was further on than the next field. Two of the younger members (only in their fifties) set off in hot pursuit & managed to pin it down two fields away across the road. Being so light there was no damage.
My FX707
Inspired by Quorneng I had built an FX707 (complete with flaps).
I asked Tom to at least do the first flight. The Wind Turbines were now turning quite steadily. Even I could see the wind was knocking it about. He managed a few minutes & got it back on the ground safely. He said when he tried to give it some throttle to fight the wind it started to climb like the proverbial HA.
Back on the ground he added loads of down elevator & set it off again. This time it was much steadier & it flew & landed well.
I had another battery but decided discretion was the better part of valour & declined the offer of flying it myself.
Other models that people flew were a Spitfire, a Hurricane, a Swiss Venom & a Macro Wot.

BUT
Not here! I got to the field for 0930 (ish), and got the cabin open and the windsock up, although why I bothered with it I don't know - it just dangled limply all day, with occasional flickers of movement! The wind was about 2mph from the South, and the sun was blazing down from a nearly blue sky - just little whispy bits of cotton wool WAAAAY up.
I'd taken the Decathlon, the Tango glider, the Kobus glider, and my Blade helicopter.
First up was the Decathlon (of course), then a cuppa.
There was a lovely perfume wafting across the field, because the farmer was muck-spreading on the adjacent one! The joys of the countryside!
Then Graham and Alan arrived, so after some chatter, I mowed the runway.
Mike was next to arrive, and put his big glider together.
In fits and starts a few more arrived, possibly put off by the incorrect dire weather forecast!
I put the Kobus and the Tango together, then flew the Blade heli, because the battery was 'done'. That's the first heli flight in about six months, so I didn't do anything spectacular, just some hovering, turns, then zooms forward and stop, - just getting my fingers used to tiny control movements again!
Jeff W wanted me to try flying his Texan/Harvard again, having sorted out the engine's missing bolts. So I checked it over, pointed out that an engine mounting bolt had worked loose again, and a nut had fallen off the exhaust clamp bolt! Some muttering and rummaging in the odds and sods box produced the required bits.
OK, engine started, controls checked that they went the right way. Taxi out, line up, full power, and it was off - about six inches, when it promptly flick-rolled left! Crunch! Left wingtip - nose - right wingtip - tail feathers splat!
After we'd picked the bits up, he went back to flying his Tundra.
Later I flew my Kobus, this time with the bigger battery, to bring the c of g forward a bit. With a 4S3300 it was a bit nervous in pitch, so I'd put a heavier 4S5000 in, and that made the world of difference. Once I'd got it trimmed out with the new balance, it was charging around the sky like it knew what it was doing. Again, I didn't do much with it, just circles and thermal chasing. (there were a few weak ones) but even the Buzzards and Gulls were flapping. With half flap, the landing was quite fast and long. John R said it came in a bit hot. Then he flew his Gladiator biplane for a while, but on landing it flipped onto it's back. I called that I might have done three touch and go's as I landed mine, but it ended up the right way up! I won't repeat what he said!
Later, I flew the Blade heli again, then the Decathlon.
As everyone was leaving at about 4, I put a new battery in the Kobus, and began throwing it around a little, getting used to how it behaved. It loops nicely, and rolls quite rapidly considering the wingspan, so I tried a couple of four-pointers. I found that it has a nice whistle to it, in a low pass with power off!
A couple more flights with the Decathon, then I called it a day, as it was quarter to six!
When I checked what was left in the Kobus batteries, I found that the first one still had 63%, and the second one 61%, I meant to check how long the flights were, but forgot. I think both were about half an hour long.
(note to self - start the stop-watch next time!)

Added days later - Does anyone bother to read this stuff, or am I wasting my time?

There are also a couple of slope gliders - all wearing the same colour scheme.

I decided to fly my Hawker P1052 (Sea Hawk with swept wings) as it had not been flown for a year since a major crash rebuild
Of all my "same scale" Hawkers it had the best flight characteristics and I wanted to see if a major rebuild and 1 year just hanging on the wall had effected how it flew.
The one item I discovered I had forgotten was the "easy grip" side panels just below the intakes that it originally had to give some grip to its very wide circular fuselage for the hand launch.
I ended up by holding it by the rear fuselage. Easy enough to grip but being a very long way behind the CG made a level hand launch difficult. I did manage to get it away thanks in no small part to its excellent thrust to weight ratio.
However after about a minute the motor cut out but recovered the instant I moved the throttle stick. After a couple more seconds it did it again. Following the "quit whist ahead" moto I landed straight away!
Conventionally BEC overheating would be considered a likely culprit but is that really likely with an instant recovery related to a change in the throttle signal!
I have in the past had similar problems with some receivers using the Hobby King TX6i transmitter's version of DSMX. I note that for all its earlier trouble free flights used my Spektrum DX6i with its "genuine" DSMX.
I shall have to loose a model off DX6i's 10 model memory limit to put the P1052 back on to see if that cures the cutting out issue.

To my surprise it cut out as before but this time I specifically did not touch the throttle and it cut back in again but being so calm and quiet I actually heard the Rx beep as it reacquired the signal!
To confirm I then set the throttle, placed the TX on the ground and walked away holding the plane in a flying attitude. Not too surprising at about 30 paces it cut but as I turned the plane through 90 degrees the motor cut back in!
A receiver aerial blanking issue?
The Rx has a single aerial lying in the fuselage under the wing pointing towards the tail.
Of course in that position when flying low it is pointing directly away so everything (motor, battery, ESC and much of the wiring is positioned exactly between the aerial and the TX.
Perhaps the FX707 has always suffered from this issue but has been unnoticed as it normally gains height fast!
Any way I have hopefully limited any "blanking" by moving the receiver from the cockpit to under the wing thus moving its aerial much further down the rear fuselage and at the same time significantly reducing the "mess" of wires in the cockpit.
So far untested as the wind today was and still is very gusty.
I suspect it will be a similar issue with the swept wing Sea Hawk although I will first try it on a Spectrum DX6i to see if it works better.
Incidentally the Hobby King TX6i is the "USA" model so has a higher power output than the approved UK 2.4 spec!
Could be a good bit calmer tomorrow.
In addition my time on my computer has been limited for 2 days as I/We changed supplier to full fibre broadband.
Prompt installation but it has taken 48 hours and some "online" complaining to get it working but of course with full fibre (it also carries the phone line) how are you expected to seek their help when it does not work!.

First flew the basic F707 Albatross.
11 minutes but I think it needs some down thrust to cure a rather pronounced power on climb. As it is using 35meg I don't have the option of a power/down elevator mix. Such a mix is possible on the Futaba Skysport but it would then apply to all my 35 meg planes!
Next I flew the Hawker P1052 but bound to a Spectrum DX6i rather than the Hobby King TX6i which gave the repeated cutting out I mentioned earlier.
As I had hoped there was no such cutting out problem using the DX6i with a 6 minute flight. It does fly on much reduced throttle and from altitude it can glide for quite some time.
Started to overcast by 6pm but still calm so I flew the Depron Seagull for a full 8 minutes on its 450mAh 3s.
Even attracted the interest of a passing SeaGull!
Finally I flew the Swiss Venom.
By far the heaviest and most powerful of the planes I flew today but like most 1950's jets it is aerodynamically pretty efficient so with throttle management I managed 6 minutes from its 1400mAh 4s that is until a group 10 of youngsters started kicking a ball around just about where I wanted to land! I flew to the extreme edge of the field to land well clear of them but managed to loose control and it "piled in"!
Some nose and wing damage but for the first time in several such "incidents" its delicate twin tail booms were completely undamaged!
Repairs already underway.

Of course nobody turned up until 1130.
Alan and Graham were first. Neither of them had brought models.
A while later, Mark arrived, and he hadn't brought anything either. Stew was next, followed by Mike who wasn't flying anything, and finally John R. He'd brought his big Tiger Moth, and his Kwik Fli. As his Moth had been parked up over winter, because it was a calm day model, is anyone reading this, it must have been resting on something, as the wing was slightly warped, making the trim tricky. So after a break, he flew his Kwik Fli, misjudged the landing, and broke the propellor. That was his flying over.
Stew flew his lightweight fun-fly a couple of times, but wasn't happy with the control throws, it was still too lively for him.
I'd taken my Decathlon, the Kobus, and the Twin Shark, but by the time the rain had stopped, I'd lost enthusiasm, so just joined in the chatter.

First I flew the revised FX707 with 3 degrees down thrust. A rather involved proceed as the nose cowling had to be removed (actually cut off!) the motor removed and a new motor mount printed with the 3 degrees down added. This meant the spinner and the front of the cowling no longer matched so the cowling had to be modified and reprinted. As I hoped the down thrust did reduce the power climb quite a bit. I had a very pleasant 18 minutes which included nearly 50% just gliding down from altitude.
Still flat calm in the after noon so I flew the Big Dragon 3
Simply because it flies well and is plenty powerful. A good 15 minutes using a full power near vertical climb of about 30 second followed by a long slow 4 minutes glide back! After it twice and some general flying about with not even a hint of any thermal activity I stopped and landed. Not even half the capacity of the big 6000mAh 3s had been used.
This evening I hoped to maiden the light weight PR9 Canberra but of course by 7pm the sun came out and the forecast wind/gusts started.
Not good condition for a lightweight maiden Don't see any really calm for the next week.
Drat and double drat!

Alan hasn't flown for years, Graham does sometimes, he's been teaching a real youngster on Saturdays - who by all accounts is flying better than Graham can, now! Neil sometimes comes on his motorbike, so carrying models isn't easy. Mark is in the process of building a big model - but that seems to be taking a long time!
Due to natural attrition, our actively flying group is slowly getting smaller.
I've sneaked in "is anyone" twice, now, and Jon is the only one to notice!
