I originally started to rebuild my 8294 boom, as I wanted to eliminate the gears on the boom, and streamline the body a bit to give it a more finished look. As I looked at the pix of the 8043 available on the internet, I decided to build the 8043 as I saw it. This is the first time I have constructed a technic from scratch. I have a couple of other construction vehicles that are not available from lego that I want to create. I thought this would be a perfect start as I really cant wait another 5 months for this kit to come out. I will buy this kit for sure, I want to see how they handled issues that I had. Using 6 M-Motors, 3 IR Receivers 2 LI Battery Packs and 3 IR remotes I started with the drive portion of the excavator separately from the body so I could work on it easily and charge batteries with ease which required 2 batteries. I believe the 8043 will come equipt with the drive linkage going through the center like on the 8258 crane truck. That is just enough to make both tracks work independently for directional control. So I believe that the red lever on the 8043 pix switches between rotation and drive. It make the most sense to me. 3 levers to operate the boom with 3 M-Motors are what operates my 8043R - R=red I believe this will be true of the 8043. 1 Lever operates rotation on my 8043R, and the last 2 levers operate movement. I will take a picture of the remote for the 8043R. This Moc took me a while as I had to hunt available parts down through Lego and Bricklink, my new found Gold Mine. My 8043R does not look exactly like the lego, as the fairings on the rear of the Excavator taper on Lego's, mine I kept to a more realistic look. Although, I will try them out to see how they look, and post pix. Also, I started out with the boom first, and had to alter that to really fit the body of the excavator. My boom operates through all movement. I could not get a clutch gear on the twin actuators though, there is too much weight for the clutch gear to handle. I built Lego's version of the boom just to see how it was. It is lighter than mine, and does not allow the bucket to be level when fully retracted. The lego boom does have a farther reach than mine though, but My plan is to lengthen the overall boom just a bit. I found that the boom on the 8294 excavator is close to the same size. The drive section is completely of my own design, as I started to build one like lego's 8043, and trashed it after I thought they were introducing a new part plus I really wanted to get rid of all the gears and look closer like the real thing.. I finally figured out what the part was while helping my son with one of his tecnics. Needless to say, I am anxious to try and mimic lego's bottom half now. Overall this excavator is a very nice model, I can't wait to build lego's version - But in reality I already have it. I hope you enjoy this Moc as much as I do. I have other altered technic kits if anyone is interested in seeing those. If there are any other views you would like to see let me know I will take a couple more pix and post them.
