I stopped into the local hobby shop who carriers a lot of crawler stuff and mentioned I was getting ready to build a berg and kamikaze setup and he mentioned to be prepared to have to take the bergs apart to debur. He had a set of bullies that belonged to another guy who worked there and said the way they were built was a lot better. I'm still learning about setups on these crawler but will most likely be ordering the bully comp crawler. Waiting to hear back about a few things before pulling the trigger. Have a ax10 pretty much stock, going to change a few things before ordering a tube chassis for it and waiting on jpcustoms pimp cane for my clod setup.
the bergs need nothing done to them except tightening and lock tighting the internal screws, other than that they are ready to go right out of the box. the only real reason the bullies are more is because the are rc4wd's so they are automatically priced to high lol.
