Try the CH-UN180 from http://www.batteryspace.com/
Multi-Current Universal Smart Charger for 9.6V - 18V NiMH Battery Packs CH-UN180 1 $30.95
Component: Temperature sensor ( 70 C, BEC Male plug ) for Smart NiMH Charger with cable / Connector 1 $3.99
I would also purchase at least one spare Thermister as well.
I use this setup on my FB-78 and it is a nice solution.
They also have a lot of info on their website on NiMH battery charging. Best method is a thermister controlled negative delta T which is what the CH-UN180 is. It will work for mulyiple style of packs and is sufficient to charge the 11 cells in the FB-78.
