Flying again!
Well Known Member
I am going to replace the battery my -10 came with with a much lighter Shorai LFX36L3. Current battery (Odyssey 1200) is fine but limits me due to aft CG with 4 people and luggage. Example: currently with my family on board and 80 pounds of baggage I am the aft CG limit when I reach 30 pounds of fuel remaining.
Preliminary calculations show a 33.5 pound saving swapping out the battery! I measured from the rear seat to the battery and came up with an arm of 196.94 but do not know if this is correct.
Anyway, with weight savings and my estimated moment arm I have no aft CG issue. With my family and 100 pounds of luggage I can go to zero fuel remaining and still be within the CG range. With just me and full fuel my CG is at the forward CG but not an issue but I may swap batteries if I am only flying with 1 or 2 passengers and wanted the moment arm so I can account for the change.
I will weigh the -10 next month after the condition inspection since a couple of other things are being installed and I want a new measured W&B.
