Dear Guy,
Personally, I don't understand the spirit of the AA rules if we accept expensive powerfull heavy jet on one side and light propeller plane on the other?! (like Robert Herzog told you as well) I don't understand either why biplane, triplane, etc. shoud be keept away from a competition which mix prop plane, helicopter and jet... Keep it affordable: A 3m plane is expensive! But to travel with is even more expensive and difficult. (some wellknown and sponsorized pilots keep their plane on the other side of the Atlantique for the next event due to that reason!)
That's why we need limits.
Keep it natural:
The 8kg limit  from Donatas is a very good start.
A usual 8kg biplane is around 1.8m and a 8kg monoplane around 2.2m
(fuel, smoke, battery, etc included?...)
As told before, this allows cheaper gas engines.
If somebody can build a 2.5m biplane at that weight: congratulations, that's just well done! The spectators will see a different kind of flight: "Great isn't it!" Keep it free: About the noise: throttle is a proportional control. You can really enhance a flight on music with the noise of your plane (engine, but prop or even the whistling of the plane :-)
If nobody can hear the music, I don't think the points will be good.
Why a pilot could not make the engine/prop screaming during some hard rock or classical fortissimo!? Just my 2cents Best regards,
Benoit

    Dear all,

    As most of you know, the amendment proposals that were not
    discussed during the last CIAM Plenary will be presented again at
    the next meeting.

    One of these proposals may need further discussion. It concerns
    the deletion of the weight limit for F6A airplanes. It has been
    pointed to me that the amended rule (2 m maximum wingspan, no
    weight limit) woudl open the way to multiplane monsters (think
    about a 2-metres, 15 kg, DA-150-powered Ultimate. This would
    obvioulsy negate the spirit of the present AA rules.

    One of the options I was offered was to further limit the wingspan
    for biplanes, as it is done with some freestyle classes. However,
    thinking about it and noting the fact that biplaned have
    completely disappeared from the competition circuit for years., I
    tend to think that the most adequate solution would be to limit AA
    competitions to monoplanes.

    Your input, please.

Guy R.
Thanks for your input, Benoit. I globally agree with you. In favor of the limited size, the only valuable argument was the cost of transportation. If we can settle on a 8 kg limit, because a significant number of pilots are likely to have such models ready for the competition, OK for me. In the past, the limit to 5 kg and 2 m was clearly keeping too many people away from participating. And the most motivated ones did build a model on purpose, remember ? ;-)
