It seems to me that about a year ago, I read in one of the magazines
that French model aviation was regulated by their version of the
F.A.A. The 11 lb. weight limit may just somehow have become a part of
their Federal Regulations. I can see how, if what I understood is
true, that there could have been a migration of the rule that carried
over into every modeling activity, including international
participation. Anybody have any more information? Bill Glaze<br>

<pre wrap="">Also important to realize that the Model Aircraft definition in FAI was intended *primarily* for record-setting attempts. Since precision aerobatics are not record-setting (at least not supposed to be ;-)), it would seem just another example of an un-needed rule/guideline.
One of the areas of concern I have had for a long time is the rationale behind KEEPING certain rules on the books, long after they have served their purpose, or the game has changed around them.
This may be just another reason to focus on AMA pattern rules, and get THOSE right for the purposes intended. I think someone (John P.?) posted a "minimum weight" requirement?
Seems like that would be pretty effective and would let lesser builders compete legally. Unneeded weight has never been anything other than a hindrance, has it??

Now that you mention it, the 5kg limit for record attempts is the takeoff weight. The model that Maynard Hill flew across the Atlantic had to weigh under 5kg when it was launched, if I am not mistaken. Over half the weight was fuel.
So, now the question is why does FAI pattern specify the weight without fuel? Hmmm...
BTW, I think Maynard Hill also holds the altitude record, or did at one time, something like 27k feet. I also believe it had a heater for the radio compartment.

In 2003 I had the opportunity to go to the Nats. One day, I visited the AMA museum. When I was there I had the chance to talk with the curator. He gave me a great tour. During the tour he got a phone call from a modeler in Colorado claiming that he broke the altitude for world record using a model airplane. It was not good day for him since the curator told him that he was short for several thousand feet. In the conversation they talk about the weight of the model. When they finished I ask him what is the weight requirement for breaking records. He responded " For model airplanes the maximum weight is 5 kgs or 11 lbs. Anything over 11 lbs can not be use to set records using model airplanes". I think this is the simple reason why the maximum weight is 11lbs to be considered a model airplane.
I think this is the single reason why we have the 5Kgs = 11 lbs limit. This is International rule for model airplanes. Therefore, it could be very difficult to change the weight limits.
