Thread: Size Limitations for Multirotors

I think Dave, some consideration has to be given to an MR having a " buzz saw " at each corner

But the guidelines of a planned flight, backed up with a spotter, and in line of sight

Go someway to limit the MRs flight to a safe margin

And has been said, 7kg, 1.60, 22cc, and a 60/1500w rotor are more easily quantifiable

I watch with interest, as you boffs will surely sort this meaningful quandary out.

Spotters are only mandated with FPV and not restricted to MRs

For me the question really is, should France have rushed to support a regime, that had engaged in State Sponsored Terrorism. I am making an assumption that not only was Austria aware that the assassination was directed by Serbia by the training and support of the assassins.

In my opinion, a balanced approach would have been to leave Serbia and Austria to sort out the issues between them. At that point i would have assumed that the Austrians would have won. The opportunity to apply pressure on the Austrians, could have lead to an agreement where the Austrians left Serbia etc for guarantees of future conduct. I know that this scenario is similar to the Prussians withdrawing from France.

I think that Mat Hastings must be deliberately not recognising what passed for Democracy at the time.

At the outbreak of WW1 most working men did not have a vote, if they did not own property, in the UK. All British men acquired this right in 1918, some women also got a vote (owned property aged +30).. It was not until 1928 when the qualification to vote was equalised with men. At the beginning of WW1, the monarchy still was very influential in the UK. No NHS existed in the UK or any other form pensions etc, for ordinary workers.

So how different was Germany (as that is where most attention seems to fall). The German men got to vote in 1867 (in the Northern Federation). By 1871 all of what we knew as Germany had the vote. Taking health services and pensions etc, Bismark started these in Germany from 1871. Yes the Kaiser had a lot of influence, although it appears not as unique for the period as it now seems when looked at in isolation.

I personally could not hazard a guess what the outcome to the protagonists would have been if Germany etc had won. Although the treaty of Versailles had many of the seeds that almost made a WW2 inevitable. The French never stopped pushing eastwards, the frequent demands for more reparations ensured that tensions remained and increased etc.

It is in the last area where lessons were learned after the end of WW2, where the USA reigned in the most excessive demands of some. It is probably the USA that has endeavoured to maintain world piece, that has been the most important aspect of our live times.

France did not support a "sponsor of state terror" at all -

  • August 2nd Germany Invades Luxembourg
  • 6am August 2nd German troops violate the French border at Joncherry
  • August 3rd Germany declares war on France
  • August 4th Germany invades Belgium
  • August 4th Britain declares war on Germany

Male suffrage in the UK, the "Representation of the People Act" 1884 extended the vote to all males paying rent of over £10 per year or owning property valued at over £10 bring the voting population to 5.5 million

Whilst there was indeed universal suffrage in Germany from 1871 the value of the vote was far lower that the vote in the UK because the effective government in Germany was not under the control of the parliament but appointed by and responsible to the crown

XK50, it was paid for by a UK government fund, financed by the fines levied on the banks for their (more than usual) dishonest and unethical activities.

If you are referring to the Commonwealth Wargraves Commission, you are totally wrong it has been paid for jointly by six commonwealth nations since its inception in 1917 on a pro-rata basis - and having visited and been humbled by the wonderful way those resting places are maintained

Thread: Traplet statement

Perhaps we should hold off the rejoycing for a while, at least until we understand the full meaning of the phrase "they have acquired the rights to sell many of the products and services previously offered by Traplet"

Traplet had many different portfolios in differing hobbies and crafts - as "many" does not mean "all" we are not yet out of the woods as t were

At the time Great Britain, her Allies principally the French, her Dominions and her Empire had been at war with Germany for nearly three years.


There is no right answer.

To embroider the post above.... Keep in mind the reason we were in the war was to regain Belgian independence, as Germany was occupying large portions of it and after the halting of their early war advances (first battle of the Marne) they basically fell back a little to the best positions available (the higher ground) and settled down to static warfare to concentrate their efforts in the East - leaving the western allies a choice of accepting German occupation or attacking them - the Germans mounted only limited offensives in the west for the reminder of the war until 1918 with the Micheal Offensive when they tried to knock Britain out of the war before the main body of the US Army was operational in France - so the western allies had no political choice but to attack - the issue was how to break the overpowering advantage that prepared positions and machine guns and indirect artillery fire gave to the defence - that took time

31/07/2017 21:23:13

Please dont misunderstand my posts - my family lost two in the first war, one in Palestine buried in what is now the Gaza Strip, and one in Devils Wood in the middle phase of the Somme Offensive (he was 17 and already survived Gallipoli having lied about his age)

But I ask myself if we had not gone to war in 1914 what would have been the result? The answers I always come back to seems to point out that it was for a reason we fought

31/07/2017 21:13:10

One of the problems associated with WW1 is the lack of clarity of "why we fought" - unlike WW2 where the horrors were all too apparent they were much more subtle in WW1 - the historians of the 50s and 60s (which formed the basis for what we commonly hold as the popular view) voiced opinions and analysis against the background of WW2, but as many many records came into the public area under the 60 year rule - a great deal of re-evaluation has been done with the benefit of these insights

Max Hastings wrote quite a compelling piece on it **LINK**

31/07/2017 20:57:33

Without the intention of starting an argument or offending anyone's feelings

It was a war that had to be fought, just as much as the second the historians of the 1960's who portrayed it as a "pointless war" have a lot to answer for I am afraid

Does anyone know whats happened to the plans store? has it gone for good?

The will be under the control of the official receiver as the plans form an asset of the company - if the receiver cant sell the company as a going concern they will end up being sold to raise money for the creditors as will any other assets of the company

Really depends on what you are building as the weights of the various coverings vary hugely

Just to let you all know that several people have contacted me, in the background, offering help with getting parts and plans sorted. The loan of a cowl to copy etc. It is very kind of you all and just shows what we are made of. If Traplet doesn't come through for us we will find a way, never fear.



Take care Danny, that kindness and good will might well constitute copyright infringement.......

Nice find Colin

Maybe a bit boring but I actually like the yellow trainer scheme with the polished cowel.


Nice colour scheme but one draw back with yellow - it attracts insects like hell

Dont need permission , the fields are abandoned land which use to get used for motorbikes etc , the ash parks are also never used and have a length totalling roughly 3/4 mile long by about a 1/4 mile wide ,the grass parks are regularly empty as well ... i feel i have plenty of room for a sports cub id imagine. Also no cars are visible and houses are a fair distance away. Im sorry but not everyone needs to join a club to be able to find an area to fly in. I have sent both hamilton and clyde view (shotts) clubs emails but im not holding my breath as shotts is a heli club and the members seem to be the older generation , preferably if i was to join a club it would have members around my age.

a) There is no such thing as "abandoned land" someone owns it....

b) If its surrounded by trees be aware that wind conditions/directions can be very different above and below the treeline - can catch you out when you are taking off and climbing out with litter energy spare

c) Be aware of the legal requirements that are mandated under CAP658 **LINK**

d) Whilst its not a legal requirement (yet) think carefully about the consequences of flying without 3rd party insurance (its cheap enough £29) via someone like the Scottish Aeromodellers Association as either a club member or as a independent country member **LINK**

RAF museum in North London is well worth a visit, easy access from the M25.

While visiting the Peak District the Manchester museum of Science and Technology is worth a visit. Lots of Avro stuff there (local company) And if you take the wife, Coronation Street is just round the corner.

I think the Old Corrie set was demolished earlier this year - it was open for a couple of years after the film set was rebuilt in Media City - I dont think you can do a visit the new set

The Shuttleworth Collection @ Old Warden are having a flying day on the 3rd Sept **LINK**

If you want to do a photo shoot of a particular aircraft its probably best to contact them directly and ask (the worst you will get in "No"!)

The Imperial War Museum at Duxford is well worth a visit **LINK**
