How Can i Fix My Reciever?

[brushlessboy16]

Hey guys. i was Driving my raze late yester day and my Antenna holder broke loose from the chassis and the tube and wire got sucked up into my outrunner and drivetrain

well now lets say that my antenna wire is in three peices.

Ther is a short stub coming out of the receiver itself that i should be able to solder to.
Will soldering to the antenna wire hurt anything?
am i better off soldering a whole new wire onto the Rx?
I popped open the reciever and there is this white almost rubber-ish insulation on where the wire needs to go.... is it safe to remove?
