Default 3500 mAh 7.2 Volt Ni-Cd vs Ni-MH

Are these batteries (3500 mAh, 7.2 Volt Ni-Cd vs Ni-MH) interchangeable for an old R/C motor requiring 7.2 volts that ran on Ni-Cd? I am assuming the connectors are the same. I realize the Ni-MH doesn't 'slow down' like the Ni-Cd but what else is different? Weight? What about heat?

Their performance will be comparable if the "C" rating is similar. They must be capable of the discharge currents your motor will demand. Frankly, unless there was some reason why it wasn't practical, I'd probably just change to two cell LiPo or LiFe power. Both would be in the same voltage range and battery costs would be less than Nixx. You would need a Lixx capable charger.
