  38. Right, if the circuit is open no current flows to the other cells. Next question
  39. would be, what is the percentage of success of restoring a dead cell, and how long
  40. will it last. ?? If one cell went bad in the first place, wouldn't it be worth by
  41. replacing the cell ??, in which case you may apply my first respons.
  42. On the other hand, when i fly my Schlueter Magic, worth a couple thousand, comes down
  43. because of 20 bucks worth Ni-Cd cells, could realy get me pi.... !!
  44.  
  45. The battery pack is the cheapest thing in our hobby, in order to radio-control just
  46. about anything, and if it's in air it is crucial for your flying thing to be perfect.
  47.  
  48. What i'm trying to emphasis is,  PROTECT YOUR INVESTMENT AND KEEP HAVING FUN,
  49. i've seen quite a few people quiting, because they tryed to save money in the
  50. wrong place.
