Got a crawler in trade need help.

[reno911]

So I ended up trading some stuff for a nice axial crawler. It has a bunch of stuff done to it and I need some help since I am a foreigner when it comes to crawlers. This thing is pretty damn good at crawling the original owner states it won four of the five comps it has been in.

Do I need a three point switch for my third channel for a dig or is a two point suitable? I want to use my dx3-s on it, which has a two point, the dx3-r that it came with has a three point and it acts weird when moving the dig in and out. Probably user error.

Oh anyone here using a TCS tube chassis for an axial? I was curious which would be recommended, the edge or the eclipse. I really like the look of the eclipse.

Also I want to make it a hybrid, similar to the march edition of RC Drivers rock racer. It currently has a novak crwaler esc and 18.5t motor, can I change the rotor in the motor to make it go?

Pictures help I know I will get some up tomorrow morning.
