[NSRCA-discussion] Electric/Glow Pros and Cons

[Bob Richards]

Dave,
   
  Thanks for the info.
   
  I've been flying some foamies with my son, and had a cheap set of 3s lipos that I have probably used for 40-50 cycles. I had them propped so that I was at the rated limit (10c) when in a hover. They now will only fly about 4 minutes hovering, (used to be about 8) but they will fly a really long time at paritial throttle. When I cycle them at a very low current, I get the rated capacity out of them. It seems to me that these packs diminish in the ability to deliver high current (higher internal impedance?). Perhaps that is the same thing you have seen with your high-powered packs.

  My understanding is that the packs still charge/discharge/balance ok, but power output diminishes before the sequence is complete – I suspect if the capacity of the packs were checked, the mah rating would be decreased compared to new.

    Dave,

     

    How much had the packs degraded? After 100 flights? 200 flights? Any idea?

      Closer to 220 accumulated from spring of 2005 to spring of 2006, at which time they were shifted to sport use.  In any case, I'm not aware of many packs going 200+ flights for pattern use.
