| My toy helicopter, this was selling in the
shops for £30 and is now on ebay for £10, I paid £0.99 plus £8.99
postage. The model is charged from
the infrared transmitter which takes about 10 minutes. The model weighs
less than half an ounce and is soon blown away by the slightest breeze,
fly it indoors or outside when it is calm. I needed full right trim and
full right stick to stop it spinning at first, this is now OK perhaps
the tail rotor motor needed running in. To take off I use full power and
full right, then reduce power and bring the yaw stick back to neutral. I
have added some nose weight to make it fly forward. This would be useless to learn to fly helicopters, it is just a toy, the only control is up, down and yaw. I have managed to take off fly round the roon and land in the same place a few times. |

Tuesday 12th
An excellent evening on Frocester with
consistent good lift.
The Flair Heron and Graupner Discus flew
well, despite the Discus's airbrakes keep popping out. I must have the
adjustment wrong somewhere.
We had a visitor from Plymouth flying a
Multiplex ASW27B with a brushless motor which was very quick and did
well even when the wind dropped off.
Attached images are from a camera phone so
apologies for the quality.
Michael I flew in the afternoon, also on Frocester, the lift was very strong Phil.
Wednesday, good lift at Frocester in the morning, rain in the
afternoon followed by a light southerly wind

| Sunday at Haresfield started with some good slope lift, but ended with just thermal lift at lunchtime. All the models flew well at different times My Viltis was up with the thermalling birds when Peter flew it but failed when it was my turn giving me a long walk (twice). Mike's Alula impressed me with it's ability to follow small patches of lift |

Pyramidal orchid and a Marbled white |
|
| The Marbled White (Melanargia galathea) is a butterfly in the family Nymphalidae. Found across most of Europe (not Scandinavia), north Africa and as far east as Iran. The late twentieth century has seen an expansion of its range in the UK. | |
 |
Despite its common name this butterfly is one of the "browns", subfamily Satyrinae. They are a common sight in unimproved grasslands across southern Britain, particularly on the South Downs. Like other members of its subfamily, the larvae feed on various grasses. The full range is unknown but it is thought that Red Fescue Festuca rubra is essential in their diet. Eggs are laid on the wing or from brief perches on grass stems and are just sprinkled among the grass stems. Upon hatching the larvae immediately enter hibernation and only feed the following spring when the fresh growth occurs. They are a lime green with a dark green line running down the middle of their back. Pupation takes place at ground level in a loose cocoon. Adults emerge in July and on a good site in warm, sunny weather thousands can be seen gently fluttering amongst the grass heads. |
