Not pattern exactly, but..... was Re: Technology and Paticipation

One of my fellow club members, Georgio Azallin, is working on about 20  
Electric World records of various types, and altitude is one of them. I saw his  
"real time" telemetry data on his computer just yesterday. Direct dowload from  
his model to the lap top. At this altitude, he has to fly the model via video  
and he has a set of goggles he uses for that purpose. Cool as h..l. I can't 
say  how high his went, but it was pretty high. 
 
Geo said his model went into a spin at a height of..... (I can't say),  and 
it lost about 1 mile of altitude before re-gaining control.  After the final 
altitude was reached, and he stopped the motor, it took 45  minutes to get it 
back down. 
 
His takoff weight limit is indeed 5 kg, by FAI regs.

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.
