Dave Patrick 60' span Ultimate
i have ran the following motors:
1st satio 180 great
2nd RCS 1.4 decent
3rd OS-160 great
the RCS doesn't have enough power to reallly enjoy the plane 250-300 feet of verticle then it runs out. 8 oz on 12-15 minutes flights of gas so that part was always great. Mine weighted 12 3/4 with the 1.4.
