I have the Prolink electric PST Reaction ARF set in my kit built Reaction. I've got about 75 flights on it and am very happy with the gear. They are not a drop replacement if the plane is already built. Besides having to modify the nose gear mounting, as mentioned, you'll have to relocate the main wheel wells. The main struts are about an inch longer than the Robart wire struts. Also you should have done the mains first. That way you can adjust the height of the nose gear horizontal mount to give the plane the proper attitude.
Attached are a couple of pictures that show what I needed to do when building my kit.
