<DIV><FONT face=Arial size=2>Don't forget this option only addresses AMA
flown completion. FAI still has to follow the current rule. While I
don't agree with any supposed rationale to increase the weight limit because of
electric or whatever the current flavor, I have seen to many bad effects after
this kind of thinking to the negative for the growth of the sport. If some
are willing to chose to use electric as their propulsion then do the
work and open the wallet as many have done or stay with glow as many
have. Some out of necessity because we have no other option.

got the following from John Fuqua. He is going to submit a proposal to
increase the weight limit for electric-powered airplanes to 11.5 lbs.
I suggested to him that he "float" his rationale by the NSRCA Discussion
List, to get some feedback. Here is his response.

<DIV><FONT face=Arial size=2>Now that I am flying electrics I have come to
realize the penalty that electric planes have when being built that gas
planes to not have. That building penalty is significant under the
current rules. Electrics must be built lighter, to include paranoid
attention to everything used - wood, paint, fittings, etc., - all to make
weight. Much more of a concern than gas planes. Also I
remember many instances at the NATs when we were weighing airplanes, when
the contestant was doing all he could do to meet weight with a gas plane
to include cleaning the fuel residue inside and out. A lot of
gas planes were weighing in at 10lb 11oz, 10lb 11.9 oz, even one that was
only a few grams under 5 kilos. Then they get to add a minimum
of 16 to 20 ozs of weight by fueling up (and there is no limit to fuel
capacity). Takeoff weights are 12 lbs or more. This
situation seems bizarre and illogical when you put some thought into
it. Electrics have a finite weight and gas planes are open ended at
Takeoff. Even though the 2005 NSRCA survey did not support an
electric weight increase it occurred to me that the survey did not offer
any logic or rationale as to why some increase would be justified or
not. I have attempted below to come up with a reasonable compromise
on electric weight allowance. I believe the rationale supports an
increase but it would be nice to have NSRCA membership look at it to find
the fatal flaw in the rationale before it gets submitted. The two
paras below are taken from the proposed change. Lets put it
out and see what the discussion list comes up with.</FONT></DIV>

alleged shortcomings of the present rules. State intent for future
reference.</FONT></B> </DIV>
<DIV><FONT face=Arial size=2>Today’s 2 meter RC Aerobatics fuel powered
aircraft typically use fuel tanks with a 20 fluid ounce capacity. A
20 fluid ounce Crank Tank containing 25% Cool Power Pro Pattern fuel was
tested. The fuel weighed 17.3 ounces. Allowing for variation
in tank sizes and fuel type a conservative weight of 16 ounces of fuel on
average seems appropriate. This means that an allowable takeoff
weight for fuel powered aircraft is at least 12 pounds.
Assuming that all fuel is consumed during the flight, the average weight
for the aircraft is 11.5 pounds. By restricting electric powered
aircraft to the takeoff weight of unfueled aircraft an unfair weight
penalty is being arbitrarily imposed against the electric model. By
allowing electric aircraft an AVERAGE flying weight of the fuel powered
aircraft, flying weight equity is
restored.</FONT></DIV></BLOCKQUOTE></DIV><BR></DIV>_______________________________________________<BR>NSRCA-discussion
