Electric Weight: with or without batteries at US Nationals

[Jim_Woodward at beaerospace.com]

RS - Although I have taken GREAT care with the airframe weight of the 
Impact, I have used a non-exotic equipment list, so I am at 11 lbs, 4.5 oz 
with 6000 mah TP packs (2, 5S,3P).  I did not use aluminum wheel axles, 
nor replace the wheel pants, nor replace the heavy wing tube.  Also, I 
used the Futaba 9152 monster servo for the rudder.  Also, I'm using the 
stock steel prop nut and spinner jam nut.  So, I used very standard 
equipment, and still came close to making the weight.  A quick solution is 
to purchase (if available), the 5300 mah packs, which in itself drops 4-5 
oz I've heard.  Dropping even 5 oz may be possible just with some 
equipment changes.  The airframe really not going to get any lighter, 
except some more trimming of the chin cowl flanges.  I'm happy with the 
build and got close to the weight limit with a very standard equipment 
set.  Also, using the 2 cell Li-ion, 2200 mah battery. 

I've heard that they may change the electric weighing procedures such that 
the battery is removed at this years nats, but looking for confirmation 
before I spend a bunch more cash.

Thanks,
Jim

Hi All, 

Does anyone happen to know what the weighing policy will be for electric 
planes at the nats (with or without batteries)? 

Also - does anyone know the source for aluminum servo screws? 

Thanks, 
Jim W.
