Doesn't seem hard to find traxxas connectors:

You'd have to double check the connector size, these connectors are available in several
sizes. They are neither male or female, all the connectors are the same.
[WHOOPS - think I'm wrong there, they may be polarised after all, I'm confusing them
with Durite style connectors]
