Electric Motors

Just Recently Got In The Electric Scene And Need Some Info On Motors. I Have Just Acquired A Very Special Truck And Want To Put The Very Best On It When It Comes To The Motor. Money Is No Object. Just Want The Best. Any Info Will Be Greatly Appreciated.
Thanks
LET ME ADD SOMETHING ELSE TO THIS THREAD. THE TRUCK IS AN EMAXX AND IT IS JUST A ROLLER. I HAVE AN OTB TRANNY AND NEED THE REST. LIKE I SAID I AM VERY NEW TO THIS AS ALL I HAVE EVER HAD IS NITRO.
