Da Rock,
The aircraft is a C2A Greyhound 1/8th scale "true to scale"
Full scale areas are as follows:
Tail= 165.13 sq ft
Wing= 700 sq ft
Flap volume (total)= 34.23%
Aileron volume (total) 12.1%
Root chord airfoil 63A216
Tip cord airfoil 63A414
Vertical stab (outboard) 63A212
Vertical stab (inboard) 63A212
Horizontal stab 64A412 (inverted)
Dihedral (centerline to tip, 65% cord) 2deg 30'
Aspect ratio 9.29

My concern stems from other models that I have built & I did not get it right & the tail dragged, in doing so I had to change the thrustline

Thank you everone for your thoughts and advise

Regards
Dave
