Note: Throws are measured at the widest part of
the elevators, rudder and ailerons. We recommend
the following control surface throws as a starting
point:
One leading cause of crashes is flying an airplane
with its control throws set differently from those
recommended in the instructions. The Great
Planes AccuThrow
™
lets you quickly and easily
measure actual throws first, so you can make
necessary corrections before you fly. Large, no-slip
rubber feet provide a firm grip on covered surfaces
without denting or marring the finish. Spring
tension holds AccuThrow’s plastic ruler steady by
each control surface. Curved to match control
motions, the ruler provides exact readings in both
standard or metric measurements. GPMR2405.
Make sure the control surfaces move in the proper
direction as illustrated in the following sketch:
Note: This section is VERY important and must
NOT be omitted! A model that is not properly
balanced will be unstable and possibly unflyable.

1. The balance point (C.G.) is located 3-1/2 [89mm]
back from the leading edge of the wing. Balance
your Hobbistar 60 using a Great Planes C.G.
Machine
™
Airplane Balancer (GPMR2400) for the
most accurate results. This is the balance point at
which your model should balance for your first
flights. Do not at any time balance your model
outside the recommended range.
❏
2. With the wing attached to the fuselage, all
parts of the model installed (ready to fly), and an
empty fuel tank, block up the tail as necessary to
level the stab. Lift the model at the desired balance
point, and observe the tail of the aircraft. If the tail
drops, the model is “tail heavy” and you must add
weight* to the nose to balance the model. If the
