The cockpit was offset to make room for the "coal hole" described by Simon, in which the radar operator/general dogsbody was incarcerated to operate the electronics. Rather him than me. The Sea Vixen had a pretty lousy accident record and I wouldn't have enjoyed being stuck down there with no real view of the outside world.

The theory was that with early CRT throwing the operator into the coal hole (with no widow) he would be able to see the display better

Anyway, regarding 'democracy' as it existed in 1914, it's important to keep a couple of things in mind about the British system. Firstly, until 1902 the Prime Minister was a member of the House of Lords and it was that body which had control - not the elected Commons. This continued until 1909 when the veto powers of the Lords were restricted (but not abolished) so they still had a fair bit of clout. In effect this meant that any suffrage had a very limited degree of control of Parliament (if any).

Regarding Belgium: while there was a treaty, the use of that was cynical (remember the British Government castigated Belgium over the treatment by their king of the Congo) and was merely an excuse as Germany was expanding its Empire and with the growth of its navy and manufacturing output was becoming a threat to Britain in the commercial sphere.

It is also worth remembering that King George V's mother (Queen Alexandra) was Danish and hated the Germans (they had taken over the German speaking province of Holstein which had, until then, been part of Denmark)

France was smarting over the 'loss' of Alsace and Lorraine (and everyone overlooked the fact that both of those 'French' territories were, in the main, German speaking provinces that had been annexed by France). One interesting point regarding Alsace/Lorraine is that, under the Treaty of Versailles, all German provinces were to have a plebiscite as to whether or not they remained part of Germany. France refused point-blank to implement that.

No doubt a lot will disagree with my assessment, but some facts have been overlooked (by all sides)

A couple of points

During the 19th century Prime Ministers existed in both houses - Peel, Gladstone and Disreali were in the commons

From 1902 Prime Ministers have been exclusively from the commons (Balfour Cambell Bannerman, Asquith, Lloyd George etc)

Secondly the House of Lords veto was removed in the Parliament Act of 1911 (though they could delay a bill and still can)

Alsace was incorporated into France in the 1640's and was siezed by Prussia after the war of 1870 - and as a result of that over 100,000 alsatians left their homes rather than be ruled by Prussia - When French Troops reoccupied it in 1918 they were cheered and welcomed.

The treaty with Belgium was convieniant of course, whilst we will never know for sure, the prospect of a German Navy based in the Belgian ports was something Britain could never tolerate and made war inevitable once Belgium was attacked

You continue to claim Germany as a paragon of democracy lets delve into that a little deeper beyond the facade of universal suffrage shall we.....

Bismark united Germany, but it was by no means a union of equals Prussia was by far the most powerful and played a highly dominant role in legislation, whilst Bismark also introduced universal suffrage (for males) the voting system was very different from a standard democracy - Prussia adopted a differential voting system where there was a "three class voting system" where voters were segregated by tax payable, which translates into a first class vote being 5% of the population but wielding around 70% of the voting power, virtually guarenteing the perpetuation of the ruling elite also voting was done orally and in public - so very open to employer influence - This placed the Prussian Junkers class in an unassailable position of privelidge and power - Due to the lack of boundary reforms during industrialistion the urban areas were grossly underrepresented so much so that in one election in Essen, Alfred Krupp was the only first class voter and effectively controlled the constituency.

Hardly a paragon of Democracy

Now lets look at the structure of the Union of German State - The Kaiser appointed the chancellor and between them were in total control of all the significant areas of Government - the Army, foreign policy and crucially could disband the Reichstag without its consent - leaving the Reichstag with basically domestic policy

In addition legislation from the Reichstag required the consent of the Bundesrat - a chamber of appointed representative from each of the original members of the German confederation, a legislature heavily biased in favour of Prussia due to the numbers of members sent - of course there were predominantly from the Junkers class all loyal to the emperor and even if the Reichstag did pass a bill that was not in line with the Kaisers wishes it would inevitably fail in the Bundesrat

So all in all Imperial Germany had a facade of Democracy but real power was highly concentrated in the Kaiser - hardly the paragon of democracy when you get past the superficial layer of state function

Add into the mix a Kaiser who was weak and under the influence of senior Army generals and you effectively have a Autocratic Monarchy controlled by a military elite - Not the paragon of democracy you like to think it was

You can always find differences between different systems, in these cases Democracies.

My contention would be that the UK was not a democracy at all, over 40% of men and approaching 100% of women did not have a vote. That the prime minister decided to declare war, that the issue was discussed with the then King.

I could go on with this type of argument seeking out differences.

Yet at the end of the day WW1 was not a fight for Democracy, in any form. As has been highlighted by others a consequence to a large extent of mutual support agreements, seeking to get even from perceived slights.

Again as alluded to by some, it is the decline in both the Austo-Hungarian and Ottoman Empires, that Serbia is seeking to exploit for its own gain, by Serbian Ggovernment officials, arming, training and targeting a foreign state to cause unrest that is the catalyst. In principle this is no longer disputed that it was officially sanctioned assassination.

In essence this was a dispute that really should have remained local, with good sense and less reckless actions by both sides. The assassination would be a foot note in history.

Indeed it was not particularly a war for democracy, in 1914 it could be argued that none of the major states were democratic as we define it today

The Second Reich was a "Authoritarian Monarchy" not a democracy as the Monarch was not constrained by an elected body, but a system where all significant decisions were made by the monarch and.or his appointed chancellor and those decisions were not challengable in the riechstag

The situation in the UK was that of a constitutional monarchy, the monarch was not empowered to initiate any decisions, that power lay with the elected government, while it is true that there is no need for a government to ask parliament before declaring war non the less the government is subject to a vote of no confidence and removal from office should it loose that vote

So in 1914 we had a partial electorate in germany voting for a body with severely limited powers, against a more restricted electorate voting for a body with absolute power in the UK - Neither true democracies (and could not be until universal suffrage - including women - were introduced) but on the political IV scales used to measure levels of democracy Germany was far lower on the scale than the UK

That is both my opinion and that of every academic study including German ones, across the world for the last 100 years - you can put forwards all the tangental objections you wish but yours will be a voice in the wilderness, I will leave you with the suggestion that you read of the machinations of Theobald von Bethmann Hollweg the German Chancellor particularly during the "August Crisis"

Helos - 1500mm Rotor Diam and 0.60cu/10cc or 1500W Electric

Whilst I am not sure why the helicopter power limits could not be the same as the fixed wing power limits, do you not already have a size and power limit for rotor craft?

Partially noise as the motor and blade noise combine + the fact that Helos tend to stay close to the ground

Not a bad idea but perhaps simplify it to Helos and MR restricted to 200yds from Pilot?

Manually, I suppose it's a subjective issue as to what is 200yds - opinions may vary depending on whether it's the flyer or the Safety Officer....teeth 2

With the geofencing, it's determined electronically and the pilot will be over-ridden. However, either way it depends on the integrity of the pilot, either by observation or by setting the correct parameter. I use the Pixhawk FC and you'll need a laptop at the field to check the flight parameters that have been set.

I'd certainly not want to fly mine in manual mode much further than 200yds - orientation's awful without wings and a tail!teeth 2

Pete

As not all MR have geo fencing we cant really make a club rule that is dependent on it - yes 200yds is subjective but at least it reminds people that they should not stray too far away

One of my points is that WW1 was not in any real sense about demoracy, either defending the concept or bringing the concept to others. The idea that the German government was totally ineffectual, The following is a cut and paste.

The Reichstag (German: [ˈʁaɪçstaːk], Diet of the Realm[1] or Imperial Diet) was the Parliament of Germany from 1871 to 1918. Legislation was shared between the Reichstag and the Bundesrat, which was the Imperial Council of the reigning princes of the German States.

The Reichstag had no formal right to appoint or dismiss governments, but by contemporary standards it was considered a highly modern and progressive parliament. All German men over 25 years of age were eligible to vote, and members of the Reichstag were elected by general, universal and secret suffrage. Members were elected in single-member constituencies by majority vote. If no candidate received a majority of the votes, a runoff election took place. In 1871, the Reichstag consisted of 382 members, but from 1874 it was enlarged to 397 members.[2]

The term of office was initially set at three years, and in 1888 this was extended to five years. The Reichstag was opened once a year by the Emperor. In order to dissolve parliament, the approval of the Imperial Council and the emperor were required. Members of parliament enjoyed legal immunity and indemnity.

There are some structural similarities with our own parliament with respect to the house of Lords (until recently).

Edited By Erfolg on 04/08/2017 12:04:03

All correct but it ignores the powers of the Reich Chancellor who was appointed by the Emperor - Imperial decrees only needed to signature of the Reich Chancellor to become law - Imperial edicts were not subject to ratification bt the Reichstag - reducing the parliament to little more than a talking shop with the powers of a local council

What is missed out is that Russia supports Serbia. Then France declares it support for Russia. Many other bits of the puzzle are glossed over by both approaches.

In recent years, and some shared experiences at nation level, have engendered a view that State Sponsored Terrorism is not acceptable by a state, and any other state that supports such a regime. No doubt this view will change with time. Today the actions of Serbia would be roundly condemned by all, and any other states that choose to go to their support. The problem is that all the military pull out the plans that they have developed with time, for various circumstances. Even today, one of my cousins was employed as a mathematician, working on the probable outcomes of various plans and responses to them.

The fact that Germans all had a vote, does demonstrate that from a democratic perspective, that the qualification requirements were less onerous than the UK. Over 40% of males prior to 1918 did not qualify to vote. You have to spin the facts a long way, to argue that Germany was less democratic than the UK, at that time.

For me the tragedy of WW1 was that to many did not pause long enough to consider where they were probably heading. It seems very similar to the position of North Korea, a reckless leader, that is intent on provocation. Who could easily obtain a reaction that could have far reaching consequences. To many egos were at stake, in all countries.

What WW1, 2, Korean and many other wars should teach us, they rarely go completely as the error range would suggest and many lives will be ruined and the financial costs are significant.

Firstly "State Sponsored Terror" - Serbia was split between moderates and nationalists who wanted a "greater serbia" at the expense of the (crumbling) Austro Hungarian Empire - The assignation was not a justifiable cause for war (a close analogy would have been the UK declaring war on the Republic of Ireland after the assignation of Lord Mountbatten) - even the Austrians knew the ultimatum sent to Serbia (after checking with Berlin for support) was unacceptably humiliating to Serbia and designed to be so to create opportunity for a "short war with Serbia" - Surprising Serbia agreed to almost all of Vienna's demand bar one (That Austria took over the on-going enquiry into the investigation) - Vienna rejected the offer, Britain made an offer to mediate between the two but the offer was ignored by Berlin and Vienna and ignored offers by Britain to mediate, The German Chancellor Bethmann Hollweg tried to restrain Austria but after the Kaisers comment "Halt in Belgrade" Austria declared war 2 days later - Russia announced mobilisation, Germany declares war on France and Russia.....

Whilst there was no formal treaty between Russia and Serbia however there was a very public and open bilateral agreement between the two states dating back to the 1870s,

As for suffrage it only has value if the body you are electing had any power, electing a parliament that can do nothing in terms of legislation is not a democracy, in Germany in 1914 the executive held all power and was appointed by the patronage of the Kaiser and was neither responsible to or controlled by any elected body - so to class German in 1914 as a democracy is highly misleading, when the executive was almost exclusively selected from a small group of military families who exerted extraordinary influence over the Kaiser to such an extent that it was effectively a military junta

For MR's with GPS, it's easy enough to geofence the MR to a set radius from take-off point, say 200-300m. If the MR reaches that limit, RTH should activate.

A simple requirement for flying from a club site, perhaps?

LOS is a legal requirement anyway - so we dont need to club rule to that effect

We allow 6 models in the air at the same time so we dont really need to specify a time limit (though if that does become an issue we would address it then)
