[NSRCA-discussion] Airplane Weight

[John Fuqua]

Totally disagree.    When you have absolute knowledge that the scales are
accurate and rules say the scale can read 5050 then the actual limit is not
5000 but 5050.

The "inconsistencies" are the inconsistencies between the pilots weighing
equipment at home and the weighing equipment used at the contest.  

 

So, if you count on your equipment being "dead accurate" and come with a
5050g airplane knowing it's 5050g, and the scales at the venue are off on
the slightly heavy side, you will, in fact, be too heavy.  This, in fact,
happened to Joseph at the last worlds, he knew he was heavy with that set of
batteries, and the scale caught him.

 

The LIMIT is 5000g, the tolerance is there in case your scales or the
venue's scales are a little bit off.  The limit is not 5050g.

Typo in second paragraph.  Should have been 5000gm, not 50000gm.  Sorry.

maximum weight of 50000gm, or 50gm.

calibration weights).  That meant we knew exactly what the airplanes
weighed.

but the weighing equipment is in error by 25 grams.  So the scales would
measure the contestant's airplane at 5075gm.  Remember that the 15 allowance
is for "possible inconsistencies in measuring equipment".  The contestant's
airplane is "too heavy".
