I run both a P-180 and a Pegasus NL...AMT USA Pegasus is identical size as well.....I use BVM #559 straps for both of them.........no significant difference between the 2 motors...BV does ship those straps with the large bypass option on the UltraBandit to be used either for 180 or Pegasus....I do use the steel shims that BV ships with the straps to fine tune them.....the motor cases are fine tune honed, but BV's straps can be oversized by few thou.....
