I am new to heli's and I bought 2 used MCPx's along with some parts and a handful of batteries. I am trying to figure out what the connector at the end of the battery is called. Some places call them ultra micro's but I have some Flyzone airplanes (Nieuport for example) that the batteries are about 1/2 the size of the MCPX batteries and the connectors at the end apparently are also called ultra micros. The problem is the MCPX connector is slightly larger so I can't use the same charger. Is there a charger out there that I can use with both types of batteries and does each connector go by a different name? Thanks.
