NIMH fly/ nofly VOLTS
NIMH cells have a shallow discharge curve at low current draws. If charged properly this means that they'll show a steady 1.2v-1.3v per cell for a good long time, then whoof! the current drops.
I had a 1600 mAh pack in my old transmitter, and it displayed this tendency. 10.1v for hours and hours, then a rapid drop to 8.8v (at which point the TX BATT alarm would go off.)
Your best bet - peak the pack, then time a couple of flights. Discharge the pack and record the amount of mAh remaining, and you'll know how much juice your radio setup is consuming per flight, and will have a better idea of when to recharge.
