Tim,
If I may, that is a nice response to Lance and I do understand what you are
saying, but a couple of my comments would be that these CB members should
have some time and wisdom relating to the issues at hand. In that vein I
believe most of the time they respond to the membership desires. However,
if they see an issue with which experience has shown them the vote would not
be in the best interest of the sport, that or those
CB members might risk a different vote.
The main reason that CB members are on the board way past their productive
time is apathy, not them, but us, the membership. So if the board is not
any good, it is our fault, not AMA or the system.
We need to force a change going through channels.
Respects,
Mike

Lance, first off let me apologize for ruffling feathers it was not meant as
a slam on those that freely give of their time and effort. I know you guys
want whats best for our sport.
This one CB member I had the run in with was years ago, in fact decades ago.
I didn't take kindly to the rebuff. In fact it made me hopping mad at the
time. It wasn't the subject matter at hand either but the fact he wouldn't
even discuss it as he is required to do.
I applaud the NSRCA for leading the charge in the rules process for our
sport.
My problem is we have 11 guys with votes that count without a recourse to
the general membership, I think this is wrong. What happens if the general
membership wants change XXX but the CB member votes against XXX? There is no
requirement for the CB member to vote the wishes of his district.
The CB is not voted into or out of office but appointed by the DVP. Which
can lead to a almost lifetime appointment.
I don't mind getting my hat handed to me at times, I was on the wrong side
of the subject back then with this CB member, I'm likely to be wrong now.

Well stated....I have seen limiting rules changed in other hobbies of mine
over the years to help make it easier for people to competehave the exact
opposite effect.
I am one of those lower class guys who whould like to see pattern become
less expensive and eliminating a limiting rule IMO is not the way.

Subject: Re: [NSRCA-discussion] weight difference
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.
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.
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.
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.
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.
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).
It's not that we're not listening... 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.
The rule change that is currently on the ballot provides a sizeable variance
for those in the lower classes to help accommodate aging aircraft (which
seem to gain weight magically), repaired used aircraft, and beginning
builders....without changing the goal (and therefore the designers goal) of
maintaining a 5KG weight limit.
Ok...off my soapbox. Sorry for the diatribe.

Lance,
Regarding the CB, I agree with you that those generalities are 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.

I have a 10 lb e-symphony, there are low 10 lb Evo's and both these planes
are super rigid an tough. There are e planes that I'm afraid to touch
because of fragility and they cost more too. Point is, the consumer has
choices and don't need to fly a dangerous airframe. They choose to. Remember
the glow Impacts that lost their tail in a snap but hundreds were sold AFTER
this fact was known on this list?
As a CB guy I don't like being generalized against. I ask for input all the
time. Even call people and tell people where my head is at all the time
without preaching.

In this day and age of instant communication we no longer need a Contest
Board to decide what we do or not. With all due respect to the CB we don't
need you guys anymore, we can poll the membership directly and set the
rules. Far more representative that way.
The only time I ever tried to talk to a CB member about a rules proposal in
person I got the old "I know better than you and I'm going to do what I want
so we don't need to discuss it." He then refused to even talk about
anything at that point. Left a very bad taste I tell you.

The rules proposal to eliminate the weight limit didn't make the first CB
vote. Too bad IMO!

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

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

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

Dave

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

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