The difference between the 260 and 300 are engine horse power.. the 260 has a shorter cockpit area, and thus a shorter
canopy. The 260 is a shoulder wing location where the 300's wing is positioned lower. You'll eventually will hear about a 330,
which is a 300 with 30 more horsepowers. They were built by Walter Extra, a German designer in Germany, and introduced
into aerobatic competitions by Patti Wagstaff, who won many National and International competitions.
