Ok, well I correctly assumed the official data was correct while you decided not to get the EZ* MkII based on what some bloke on the internet said.

There's probably a lesson for you to learn from this little episode.

Obviously someone didn't have time to check out and understand my buildlog otherwise it would become instantly obvious for that person that MY EasyStar was NOT made "by the book" so it's weight could and WILL deviate from what's stated in the manual. I admit that almost 1200g is a bit suspicious and needs to be corrected but still it's AUW of a custom made plane not stock one. If manual says that AUW stock made plane is around 700g then that's what you'll get if you follow instructions and use recommended equipment so I see no reason to argue here. I already tried to explain it to "eckace1" but it seems that some people didn't notice that explanation too.

I like real world figures from people who own them. Besides we went on the asumption his scales were accurate.

That made me laugh out loud. I know EXACTLY what you mean! Once we drive them out of the showroom, the real numbers show up.

Is the EZ2 significantly quieter with its recommended power setup than the "common" EZ1 6"x4" 2200kv configuration? I realise the question is somewhat subjective, but what I'd like to understand is whether the EZ2 can be flown in places where noise might be a concern for EZ1 owners.

Thanks for all input.

Of course I had a look at the components you used. Your motor is approx. 40g heavier than stock, your battery is approx. 100g heavier, and your ESC and servos may add additional 60g. The only real unknown is your wooden fuselage spar (most people would have used a light CRP tube here).

Whatever you do: Try to keep your model as light as possible. It is always easier to add some ballast than to add lightness.

Yep, running a bigger prop with higher pitch at much lower rpm makes the drive system much quieter and the sound frequency is a lot less "annoying".

Didn't have one so I put wood. You forgot about longer wing spar

I did to my EZ*II exactly same mods as to my previous EZ*I as they helped me a lot and I took into account that extra weight. Only difference is that I put wooden spar into tail section - in EZ*I I had carbon tube and it had some nasty effects on my RC comparing to my friend's EZ without carbon there.

No I didn't, but as a carbon spar is usually lighter than the stock glass fibre spar, any difference in weight should be negligible.

In what way would a slightly longer wing spar "help you a lot"?

A carbon tube in the fuse (or the wing) should not have any nasty affects on your RC, unless you route the antenna inside the tube. Most likely your friend used different components (RC system, ESC, motor etc.)
