I think buying geared motor is worth the extra cost. A lot of us use these like in my Sturmtiger:
http://tncscooters.com/product.php?sku=106115 My personal favorite would be these that I use in the KV-2 and the M113: http://tncscooters.com/product.php?sku=106118 The later is a little harder to mount, but is also smaller. Since they are already geared down, there is no need to further gear them down. I think it was Frank that said that he dropped 9lbs. of weight by eliminating the need for his EV gearbox by replacing them with geared motors. Correct me if I'm wrong. The added cost will be somewhat offset by the fact that if you need to gear a motor down you will have to buy additional sprockets, bearings, shafts, and chains/belts. Plus there is a frustration factor eliminated of having to construct a working gear down gearbox (personally I seem to problems getting holes to line up when I make things like gearboxes). If you look at it that way, it's a no brainer IMHO. Derek T065 SV016 KV-2 on hold On Mon, Jun 14, 2010 at 2:19 AM, Doug Conn <[email protected]> wrote: > Yes, many of use those 12v 18aH batteries.
