Paolon

thank you all for your suggestions! I will probably order a second XL motor, and remake it from the scratch. Paolo

thank you all for your welcoming! I'll try to embed the video here - not sure it works, I can see it when editing the post, but not in the preview. That's strange. Anyway, I put the extra track link to be able to put the 4 motors in line, like that... I don't know how to make it different (using 4 motors, to give it a little power). But, I think I will order an XL motor, and with the two of them I will rethink it, and it will be much stiff and compact.

good morning to everyone,my name is Paolo and I'm always been fascinated from Lego Technic. I've had many when I was a kid, then I stopped pursuing the "being adult" thing... but last year, when I went into a toy shop to buy a present for my 8 years old nephew, I felt in love with the set 8043 - a RC lego model, that was my fantasy when I was a kid! And, possessing once the 8851 (I think I lost all the bricks), it was something I couldn't resist! Then, I bought some others - 8049 (to see how was the "new" pneumatic), 8258 (a lot of pieces... and a fantastic XL motor), and recently the Unimog - wonderful set, still built.I would like to get more into MOCs, I see there are some incredible engineer in the forum - my compliments to everyone.Personally, I am still switching from the very old way of building (the old, technic bricks), to the new one, which I find very complicated sometimes, but much more durable and stiff. So, the goal is the a Compact track loader like this http://www.directind...2578-51445.html and here you can see a first video of the "basic" structure: 4 M motors... I heightened the motors from the ground, and that was the most complicated task, and now I will proceed thinking and making the rest... but probably, I want to make it with two XL motors, it's much easier to "block" them in the construction, while the M are always moving around when some torque is required. I am not sure if I can ask this in the forum... I'm from Italy, where should I buy another XL motor? Another think. I see a loto of models that doesn't use standard battery pack... If I want to make a big car moving, let's say with two XL motors and a couple of M motors, what should I do? are there some "MOC" battery pack, maybe with LiOn technology? Is it worth to buy the rechargeable batery pack from Lego? I am not sure it is easy to fit in the models... it seems an old concept to me. What do you think? many thanks for any help, you are a great forum and very, very great LEGO builders! Paolo sorry, and very not expert on posting on forums! :-)
