I am learning on an Estarter with the 400 motor and 1060 prop and using 2c1500 lipo for power. After 15 flights and 11 landings I happened to look through the instruction manual and they suggest the EP7035 prop for 7.2-8.4v. Anyone have any thoughts on what that would do. Also, have a Formosa on order and 9070 spare props. What would a 9070 prop do? Thanks alot for any input. Larry
