FB Drone twin boom...this is a scaled down version of my 4" PVC twin boom with a 60" vs a 72" wingspan. All up weight is 5lbs vs 12lbs using two paralleled 3 cell 3600 40c and a 2826/05 900kv motor vs two in-series 3 cell 3600 40c and a 4120/05 760kv motor. I like this bird and would recommend it for intermediate builder/pilots. I must also suggest installing a gyro on the roll control to stabilize for windy conditions.
Airframe specs here:
Wingspan- 60"
Wing cord-11" including 2" control surface
Nose to tail TE - 48"
Horizontal stab- 25"x7.75" total including 2"control surface
Vertical stab- 9"x9.5" total including 2" control surface
Fuse O.D.- 26.5"L x 4.25"W x 2.5"H
CofG- 3" aft of leading edge
Tail section distance from main wing- 15" from main wing TE to LE of horizontal stab
Span between aluminum arrow shaft booms - 14"
Boom length- 28.5" and braced underneath with stiff foamboard
Motor height from bottom of fuse- 7" to centerline or as needed to clear the ground + 1"
Motor- 2826/05 760kv
Prop- 13/7 APC nitro style
Motor thrust angle- point the motor shaft to just .5" forward of the main wing LE, which is approximately 15 degrees angle to the vertical motor back-plate. Adjust this angle (motor nose down) toward the CG so as to get no thrust effect on pitch with throttle up.
Batteries- 2- 3cell 3600/40c Turnigy
ESC- unknown...but at least 60a
