Vulcan at Cosford

The Avro Vulcan is an iconic example of British aerospace engineering at its world-beating best. Its impressive list of technical achievements includes being the first successful large delta wing aircraft, leading directly to Concorde and the Space Shuttle, and delivering performance and agility so close to a jet fighter’s that it was given a fighter-style control column in place of the traditional bomber pilot’s yoke. Today that agility allows XH558 to deliver amazing air displays, which unfortunately must finish this year as her time as a flying aircraft draws to an end.

News

Last week's bit about FRsky bit confused some people, I will try again, but now I'm confused

Frsky frame rate

Please take care that your Frsky receiver is set to the correct frame rate, slow for analogue servos, fast can  be used if all servos are digital. analogue servos may get hot and fail if the RX is set to fast frame rate.
Turn the transmitter off, connect the battery to the receiver, press the F/S button for 6 seconds and then release. The RED LED will flash fast in HS Mode(fast frame rate ) and slow in FS(slow frame rate) Mode. Repeat this to alternate modes.

Fast frame rate may only be used if all servos are digital, the ESC will work OK in both modes.
Slow frame rate is OK for most people slow 18 to 22 ms is about 50 per second

The only way to check the frame rate is to change it and count the flashes, they are in slow when they are new

The latency (delay) will be the same since it is primarily determined by the rate at which the transmitter itself creates the control pulses that are passed on

BREAKING NEWS: NO FLIGHT UNTIL 2016
Despite the hard work of the Solar Impulse team to repair the batteries which overheated in the record breaking oceanic flight from Nagoya to Hawaii, the solar powered airplane of Bertrand Piccard and André Borschberg will stay in Hawaii until early spring 2016.

Following the longest and most difficult leg of the round-the-world journey which lasted 5 days and 5 nights (117 hours and 52 minutes), Solar Impulse will undergo maintenance repairs on the batteries due to damages brought about by overheating.

During the first ascent on day one of the flight from Nagoya to Hawaii, the battery temperature increased due to a high climb rate and an over insulation of the gondolas. And while the Mission Team was monitoring this very closely during the flight, there was no way to decrease the temperature for the remaining duration as each daily cycle requires an ascent to 28’000 feet and descent for optimal energy management.

Overall the airplane performed very well during the flight. The damage to the batteries is not a technical failure or a weakness in the technology but rather an evaluation error in terms of the profile of the mission and the cooling design specifications of the batteries. The temperature of the batteries in a quick ascent / descent in tropical climates was not properly anticipated.

Irreversible damage to certain parts of the batteries will require repairs which will take several months. In parallel, the Solar Impulse engineering team will be studying various options for better cooling and heating processes for very long flights.

F3J/F5J news

F5J at Toldijk

It was certainly a testing comp. Sunny day with gusty winds on day one, and virtually no wind with 100% cloud on day two.

The best weather call I have ever heard was made by CD Peter Zweers at about 12o'clock on Sunday. He announced that Round 8 was cancelled (I was waiting on the flight line to fly group 1 of that round) and that there would be a 2 hour rain break.
At the time it did not seem to make any scence as nothing had changed, but within 15 minutes it was pooring down, and it lasted 2 hours.

The flyoff was actually interesting and quite exciting for us spectators and the standared of flying was very high from all contestants.
Steve even had a middair in the second flyoff, but continued flying and did not claim a refly.
He really deserved the win.
Here is podium pic and the overall scores before the flyoff.

 Great weekend, good company and the'Ladies that do' did us proud. There was such a proliferation {aint that a good word} of superb cakes and pastries, that it is easy to see why Bernie cuts such a fine figure of a man. Well he's not underweight anyway.
