Not sure about the point you are making here?

     Although you do mention a high current and henec a quick drain
     situation with the RC planes. Our use of NiMH batteries is from a
     600mAh pack being drained at around 60mA hence a 0.1C dischareg arte,a
     dn as you say an RC plane may have a discharge of 1C  .... the
     performance of the batteries in these extremely different applications
     will be very different .... I think this is a an example of what Tjart
     was talking about.


     The extremes of applications that batteries are used in, is probably
     one of the biggest reasons that the battery people do have limited
     information since each application is (almost) unique, and so unless
     you actually do try the batteries in the real application it is only
     guesswork as to how long your batteries will survive. Think about the
     braod range of factors that Tjart mentioned, and think about how they
     vary.

Those who fly electric RC planes (I mostly read about them) seldom discuss
NiCd brands, only what size of Sanyos to use. This is a high-current
application, of course.
