If at some point in the future you can get one of these, http://www3.towerhobbies.com/cgi-bin...&I=LXD712&P=ML , it is a good investment. If the prop you are balancing is to long, this balancer allows a configuration where the prop hangs outside the two supports. Then just place the balancer at the edge of a table/work bench and you can balance much longer props.
