color:#1F497D'>IMO, the weight limit restriction has driven up the cost of
aircraft and made construction more difficult for even an accomplished
builder. It also creates a potentially unsafe vessel because of trying to
make weight. What is wrong with being innovative? The weight rule
is obsolete and restrictive. The planes are becoming cookie-cutter,
boring, expensive look alikes that have minute differences. My voice is
to make the change. Seems like in all endeavors those that are the
loudest are the ones saying NO CHANGE!!!. <o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I actually feel that you’re making my point in a
way. When we were restricted by engine displacement the size and weight
were not in contention as a limiting factor (though they were, just that
without more power, they didn’t come into play).<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>The argument at the time of removing the engine displacement was
EXACTLY the one being made today (only internationally instead of just
domestically). Which was that engine displacement rule was increasing
costs because engine manufacturers were trying to get the last 1% of power out
of the existing displacement. Thus the $300 OS Hanno Special which was an
outrageous price for a .61 engine. YS was doing the same on the 4 stroke
side (another dubious rule change to provide equity between 4 stroke and 2 stroke
power plants). <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>So the goal was to allow any engine…thus letting the
“average” guy fly a cheaper, but larger displacement engine.
Did that work? Is anyone successfully running the ST 2300?? Or did
we just get bigger planes that require bigger engines…up until we hit the
size/weight limit and now we get back to expensive Engines with more expensive
CDI units?<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>What I don’t understand is that people don’t think
the planes can get any bigger because of the 2m rule. My Arch Nemesis was
a FULL 2m airplane in 1997… at 9lbs. We didn’t think
they could get any bigger then either. <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>All of that said, Contrary to Tim’s experience, I do try
hard to listen to members of my district. ALL of them…NOT just the vocal
ones that post prolifically on RCU or this list. And there are far more
in favor of maintaining the weight rule than eliminating it, or substantially
raising it. MOST…and I do mean MOST, really don’t
care. “tell me the rules, and I’ll play by them”.
That group, and it’s by far the largest group, wants consistency year to
year to year. That saves them the most money as they get a much longer
lifespan from their investment.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>The challenge here is that rules of this nature, limiting rules,
be it in Pattern, Sailing, Stock car, whatever, are NOT in place to restrict
the average guy, they’re in place to restrict the innovator. The
guys that push the limit.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>In our sport, the “average” guy is stuck pushing the
limit because he’s trying to copy and follow the innovators. We all
want the triple volumetric 2 meter bird because that’s what
Chip/Andrew/Quique and company have pushed the boundary’s too. A
prophecy still makes weight with nooooo problem. <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>So the problem is simple. IF the rules change, it clearly
will help the average guy for a year or two. But then the innovators will
once again push the limits (they wouldn’t BE limits if no one was
pushing) and we would see new designs that the average guy can’t easily
keep within the rules.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Bipes have not really caught on because they’re too
difficult to make weight with. Only the very best builders with very few
limits on funding for all the best and lightest equipment have made them
work. Add a pound and that will very likely change…to where all the
top guys can make them work, which will then push the average guy to try and
make them work. At the end of the day, all it adds is cost as we
obsolete a whole generation of viable aircraft to the dumpster. <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>All one needs to do for confirmation on that is to review the
evolution of aircraft that occurred when we removed the LAST
limiter…engine displacement. Prior to that, weight was only a
secondary limiter because displacement restricted how big of a plane you could
carry around. Once removed, we had 10 years of growing aircraft and
growing engines. All costing more, NOT just because the new stuff was
more expensive…that’s just natural inflation and evolution, but
because the lifespan of a model was shorter. Designs changed
SIGNIFICANTLY every year.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Finally, we’re back to a semi stable development cycle
which has aircraft like the Integral enjoying a 5-6 year run and is still
considered competitive even in FAI (I believe that’s what Pete Collinson
flew in the finals this year). <o:p></o:p></span></p>

We’re simply trying to avoid mistakes from the past and make as sure as
we can that the rule changes won’t have disastrous unintended
consequences. <o:p></o:p></span></p>

anal comments. Most of the guys are giving freely of their time and we
are lucky to have them. On the weight issue, the 11 pounds is a bit restricting.
When that rule was made, planes had a 60 inch span, were 48 inches long and
weighed 7 lbs. now they are volumetrically double or triple so the wing
loading is the same or lighter. Needs to go up at least a pound or two.<o:p></o:p></span></p>

I'm concerned that these new electric only planes that are designed to make<br>
weight won't hold up to the normal wear and tear of an average intermediate<br>
or advanced pilot or flying off of a rough grass runway. Is this a
valid<br>
concern? I think so but maybe I'm over reacting. That is why I'm
in favor<br>
of eliminating the weight limit altogether. The proposal to slightly
raise<br>
the weight limit won't allow someone to fly an electric Focus II for<br>
example.<br>

I've been following this with interest. E-power is looking better all the<br>
time and I probably will make the change. I like to build prefer a wood<br>
airplane. About how much total weight is in a suitable E-power system or<br>
empty airframe ready for radio etc? Any numbers readily available would be<br>
helpful in understanding the distribution of weight.<br>

And to recall.....that is the Spark with custom wings and stabs, which saves<br>
substantial weight? There are very few unmodified kits available that
are<br>
RTF electric at 10.25. There are some airframe examples for which glow
/<br>
electric are similar weight, but that is not the norm - not yet anyway - my<br>
opinion.<br>
<br>
My electric Bravo was 10 lbs even at the 2009 NATs (only 4 oz more than the<br>
Vivat I flew in 2005) and I would be scared of the structure if it were any<br>
lighter. Of course it could be lighter still IF I went from 5000 to
4350<br>
lipos (~6 oz) and ditched the dual RX batts and Vregs (~2 oz) and used<br>
lighter ESC and wiring (~ 2 oz).<br>
<br>
Point being....even tho 10 lb electrics are possible, and becoming more<br>
common, it is still pretty easy to build electrics at 11+ lbs without<br>
careful planning and attention to detail. I think it will become a<br>
non-issue soon enough.....even in Europe and Asia electrics are coming on<br>
strong.....so the glow kits will become increasingly scarce.<br>

I would argue that you can't "disregard" the airframe given that an
all<br>
electric airframe is much lighter.<br>
<br>
My answer to the question? There is almost no
difference. I'm flying a<br>
full 2M plane that weighs 10lbs 4oz with light batteries, 10lbs, 8oz with<br>
very heavy batteries. My two Black Magics with glow weighed
10lbs 6oz and<br>
10lbs 8oz RTF minus CDI (add approx 4oz for that).<br>
<br>
I believe we're just now seeing full electric designs that are optimized for<br>
weight and are coming in light. Prior to that, many of the
designs still<br>
had unnecessary structure as a legacy from Glow. I'm pretty sure that<br>
evolution is not complete yet either.<br>

Tough question. Will you insist on using 30C lipos, when 20C lipos<br>
are much lighter? Do you plan on using a particular motor? Motor<br>
weights vary substantially. Some ESCs are a lot heavier than others.<br>
<br>
My guess would be that the weight difference between a complete<br>
electric-power system and a complete glow-power system, disregarding<br>
the airplane, would be 10-16 ounces.<br>
