The tutorial looks very instructive but I must admit to being a little frustrated and wishing I had done a some research before investing all this cash into these things. The hulls are off 2 of my 3 the tanks and I am left staring at small circuit boards with a bunch of soldered wires leading from everywhere wondering if I am expected to resolder them all back on the new boards. At this point I am considering hiring someone to do the repairs. Even though I would like to learn how to do this I just don't have the time or patience for it. If there is anyone close to the North Carolina area that would like to give this repair a whirl send me an email. I am very grateful for the information I have received from all the members who have tried to help but I'm ready for FireDog. A well placed M-80 might be fun right now.
