I have a Futaba T6EX which I purchased last fall. Although it hasn't always been this bad, it now only functions between 30 & 35 mins. before the beep comes on at 8.6V.
I was using a 2200 mAh NI-MH batt pack from Battery space and just purchased two new packs (2600 mA Ni-MH) from Only batteries. All three packs when charged by my MRC Super Brain 960 AC-DC Peak Charger last only 30 mins. When fully charged, they all read 10.6v on the transmitter readout.
Any solutions/suggestions?
