That's all there is, sort of:
You will probably have to take a screw driver and gently, gently, lift the noise suppressor which is soldered between the terminals. You know, those little orange things?
Then just slide the nylon tie through one hole and back through the other.
I just selected a standard drill bit that is just a little wider than the tie wrap. I also put a piece of masking tape on the bit to mark the maximum depth I want the bit to go into the plane. This way I don't accidentally go too deep and damage the motor.
Don't press hard, the plastic is soft and the bit, if it is sharp, should go in easily.
I guess you could also just cut two slits on each side, but I think it would be hard to thread the tie through the slits.
Enjoy the bird, it is a great first plane.
