First tip, it's easier for us to build on 1/6th scale because almost all the hard work has been done for us. Most know what works and what doesn't. If you blaze out into a different direction, you are going to have to buy and test a lot of things yourself. Your motors depend of your tank weight. Make your build modular so you can switch something out easily if it doesn't work. >-- drive shafts, coupling, connecting wheels. > basicly i have no idea how to do that. i know what i would need to >do in theory, but how exactly do you connect > another longer shaft on that small shaft of a dc motor ? (its too >small to drill thru or anything) ? Most of the time the motor has a shaft that you connect either a pulley or sprocket to. You then use belt or chain to attach that to either a second belt or pulley, or sometimes directly to the main axle shafts. how do > i connect non-powered wheels (the middle ones) so they can turn on >the saft, Bearings and lock collars and how to connect the > powered wheels so they cant turn on the shaft ? Usually you use set screws, keyed shaft or you have to fabricate something to mate the shaft to the wheel (I think the Cromwell, Tiger or Comet has a good pic of this) all little things >like this, basicly some building manuals, tutorials, > books, anythings with pictures would come in handy. Read every tank build on the website, that is a bible of building. Also look at the tanks that are old and still going. Cromwell, Comet, Tiger, Hetzer, SU-100, Bad Kitty, and a few more I am forgetting. Anyone (almost) can build a website tank that never goes to a battle (me for instance), but those tanks I mentioned are punished and still run every battle. They are a guide to what works well. Also anything Frank says is gospel. -- You are currently subscribed to the "R/C Tank Combat" group.
