problem help!

[lewis666]

hi there,

i am having a problem with my cat sx.

yesterday day i bought a reedy 5000mah 40c+ from my local model shop. it fits but with millimetres's to spare. i am having a problem getting the plus bullet connector into the socket.

here are some to pictures to explain







we are confused on what to do. we did think about getting the dremel on the hole and making it oval but would this weaken the top deck?

has anyone had any kind of problem like this and how did they over come this?

many thanks

lewis
