[NSRCA-discussion] Inspection & Weighing

Mon Aug 3 16:11:09 AKDT 2009

You must have had a different guy. My guy was ALWAYS in a hurry and
generally upset when I popped the canopy to unplug the battery. He did
finally learn to say "battery" though and I learned to nod my head in the
affirmative in response. He still didn't like it though.

Verne, there is an easy way that Dave and I took care of it. Dave put the
plane down outside the tent (aimed away from everyone towards the runway),
standing over the tail and did not move until I arrived. I then had the
official watch me as I pulled open the canopy and unplugged the battery,
then put the canopy back on. Then I spun the prop and stuck my finger in
there... he usually laughed and nodded. I think everyone knows not to get
around a prop when the battery is plugged in. At least I hope so. 

But having the fully enclosed tent was great. It was closed off to the high
winds and it didn't matter what battery you weighed with during processing.
I always weigh with my heaviest battery during processing so that I know I'm
safe with the lighter one's. This month it wont be a problem as I will be
running all the same batteries with short leads.

In Argentina, there was a tent set up solely for that purpose right off the
runway. The scale had a sheet of what appeared to be drywall sitting on it
so the plane was weighed sitting on its wheels (as opposed to a belly pan
crushing stand). The only downside was having to try and explain in English
to the Spanish speaking official why it was necessary to unplug the motor
batteries before being weighed for safety's sake.

Where do they weigh at a worlds event? Outside in the wind?

Just curious. 

Thx!

Better be prepared to weigh 4 or 5 sets of batteries with each competitor as
well as airplanes.  

That's the thing with glow.  Only dry weight counts.  You can load as much
fuel as you wish to any weight!  Electric stuck at a fixed max T.O. Weight.

I don't see an issue with this... we will put a sticker on all items
including all packs that a competitor will use.  If a competitor really
wants to cheat then they will do it... nothing we can do will stop that.
I'm also hoping that random inspections will keep people honest and the fear
that if you do fail then you will be disqualified.

    I have some concern that the proposals put forward will really work.
If the plane is inspected at check-in then there is too much opportunity to
change things. In particular, batteries, which are a normally removable
item, can be changed to decrease on increase the weight. Do we "sticker" the
battery pack? This means the plane must be disassembled for inspection and
that only that battery pack can be used. At present fuel tanks can also be
under/over filled to adjust ballast for windy conditions.

    If this is a serious problem, perhaps there are other solutions. 

    Planes could be placed in an impound/inspection area immediately
before a flight and fully fueled. The inspection could happen here and
shouldn't delay the flow of the contest.

    Another possibility is to adopt a "standard" weight for a battery
pack, then weigh electric planes empty. The "standard" could change as
technology changes.

    As John Pavlick will tell you, all major race winners undergo a
teardown and inspection.
