speed gains
 

well the original plan was to report the before and after speed .the problem was with the trs drives everytime boost started coming in and i hit around 76.4 on gps thats when the drive let go.now im still putting the ten hours on for break in but ive hit 79.6 with more throttle to go and i do think that my 1990 fountain will like 5 blades.im not going to jump into the props right now because my plan is to build the hp,s to 540 cu in this winter.but as of now the upgrade was well worth it.,wes
