I have my Tera ready for the gears, but now I need to determine how I am going to get them in. I have the "stock" RC5.13 gears. I have heard that these wont fit without some work.

I am just wondering what people have done. Machine the gears down? Grind them down? How much? Grind the housing/cover a bit?

Call tera and ask them how much to take off the edge of the ring gear then take it to a machine shop.
