RE: sportsman aircraft rules?
4. Model Aircraft Specifications
4.1. Only one (1) engine of the internal combustion type or
electric motor shall be allowed.
a. The MINIMAC classification of aircraft specifies a .61 cid 2-
cycle or a .91 cid 4-cycle displacement limit. All other Scale
Aerobatics Rules will apply.
b. The IMAC classification of aircraft is comprised of models
using engines of any size.
c. MINIMAC and IMAC may be combined or kept separated
in two (2) categories at the option of the Contest Director.
4.2. An effective silencer shall be used in accordance with
AMA and club standards of noise reduction.
4.3. The model shall comply with all AMA Safety Codes.
4.4. There shall be no airborne devices fitted to the aircraft
which place the aircraft under less than total control by the
pilot. These devices will include, but are not limited to, gyros,
automatic pilots and timing devices. Non-airborne aids such as
transmitter based functions are permissible.
4.5. The Builder-of-the-Model (BOM) rule shall not apply.
5. Proof of Scale
5.1. To prove that the model resembles a particular aircraft
some proof of scale is required.
5.2. Proof of scale is the responsibility of the contestant.
5.3. The general outlines of the model shall approximate the
full size outlines of the subject aircraft. Exact scale is not
required. The model shall be judged for likeness at a distance
of approximately 10 feet.
5.4. If the contestant presents no proof of scale material with
the model, and the CD can determine that the aircraft is a
replica of a full-size aircraft, then the contestant will be allowed
to have his/her entry considered.
5.5 A realistic 3 dimensional human pilot and viewable
instrument panel shall be appropriately installed in all Scale
Aerobatic aircraft. (A one (1) percent flight score penalty will be
assessed for non-compliance.)
