connectors, which?

I am headed to my LHS after work today to buy some misc. items for my heli and a few things for the revo project. I have ordered my 1515 1y and will be coupling it to an mgm 16018 that I do not own yet. What is the best method of this connection?

Do the mgm's come with connectors that I will want to match for the motor or do I need to get a full set. If full set 4mm, 5mm?


Thanks.
