hey mike nice to meet you , a mate of mine has always done it. i actually need to myself. first go and buy a propeller balancer , there very cheap. put your wheel on , spin a few times till you keep finding the heavy spot and glue something on there till its balanced. hey presto you are now are certified tyre balancer. rc car action ran an article about it a year or so saying that an unbalanced wheel can rob 3 to 4 mphr. i have seen this method used and it works great.
