Step 5:

Preliminary Pitch-Balance Check

Now is a good time to consider the layout options for your “movable” and discretionary com-

ponents, such as Engine, Servos and Battery. The allowable Pitch C/G range is set by the planes
wing plan and your style of flying. We will temporarily mount these components and consider the
C/G options in this step.

Servo Placement Options:

GSRC has provided the Bampf with the greatest possible flexibility in placing the control servos: 1) The

Rudder servo may be placed in the wing saddle area with a “Pull-Pull” cable , or in fuselage tail with a solid push-
rod; 2) The elevator(s), may be operated with a single or dual servos. The typical sport pilot may choose to
use a single elevator servo and the “U-horn” to connect the two elevator halves; while an aggressive 3D-pilot
may want to omit the U-horn and control each elevator with individual servos. Please refer to the pictures for the
optional servo locations. See page 25 for pull-pull rudder servo location.

Check Pitch C/G Location Options:

You are going to DRY_FIT the entire Bampf together to check the Pitch C/G point. The C/G is placed

depending upon the Pilot’s flying style. The C/G is placed at the 30%-35% MAC point for sport pilots and at the
35-40% MAC point for intermediate and advanced-3D pilots respectively. The Bampf is fully pitch stable over
the entire 25%-38% MAC range. The 30% MAC C/G point is located 9-1/4” behind the front firewall surface.
The 35% MAC is located 10-1/32” behind the front firewall surface. The weight distribution variables, the
builder / pilot, controls are the engine type and weight, receiver & battery type and location, choice of plastic or
aluminum spinner, and the servo type, weight and locations.

Fully assemble (dry-fit) the Bampf by mounting the wing (with aileron servos), belly pan, all tail surfaces

(including the U-horn if using a single elevator servo), engine, tank, cowl, etc. Use masking tape to place the
individual servos & components in the appropriate locations. Do not cut holes in tail covering until your are
completely sure about servo locations.

C/G Location:

You may place the C/G decals on the wing to assist in locating the C/G more consistently. Check the C/G

with all components “installed”. Adjust the component locations to eliminate or minimize the necessity of
adding any additional weight to pitch-balance the Bampf. You may elect to change the rudder servo from the
tail location to the wing saddle location and or change from one to two elevator servos (and Vise-versa). Note,
the bigger engine you use, the more likely you will want to locate all servos on the tail (and vise-versa).

Make a note of the component locations and any additional weighting necessary. Disassemble the Bampf,

but leave the wing mounted to the fuselage for the next step.
