I am not sure how Bobby, got away with spending just $100.00 for everything. Just my 12 volt battery, fuel pump, and power panel cost that much. Prices on some stuff have come down recently such as on the tach. Mine cost $70.00 a few years ago and now a new H9 tach is listed at $37.00! I wouldn't worry about a prop balancer. I have never needed one and only once seen a prop that was a problem on another plane. By the time the pilot got through trying to balance it, it was ruined. If the grass is growing good and high, then it will build up on one side and need to be scraped off. This is the only time that I have run into a vibration problem. Have fun, Fast! :
