Hey Mario Get the ST 61 or better yet the ST 75. A guy at our field has a 4*60 with a OS61 which he was happy with till he saw my JOSS STICK 108 with a Tower 75. He said WOW I'm going to GIT me WON of DEM... Bought the TOWER 75 and said it made a whole new plane with the sound and power. I'm in love again (quote)
