Dec 27 2015, Aquila and Aquila Grande Tail Feathers

1,073 total views, 2 views today

I have built a few of the Aquilas and Aquila Grandes, and in my observations there are some differences. The fuselage length appears to be the same however there are subtle differences where the wings and horizontal stabs meet the fuselage.

I have original Airtronics “blue ” Plans for the Aquila and copied plans for the Aquila Grande.

The copied Aquila Grande plans may not be accurate as I have seen errors in plans that where either copied thru a roll type scanner / printer and or printed from electronically transferred or created  PDF files.

Tail Feathers

  • horizontal tail different shape and size

Wings

  • profile different
  • wingspan different

  • wing rod diameter larger on AG

Rudder

AG stab on bottom, root chord is longer then that of Aquila stab on top. Center to center distance is same for the 3/32″ pins

P1180124

Aquila stab on top at tip, the LE and TE sweeps are different, and the AG stab is longer

P1180121
