Equipment
To compete, you must fly the SIG
Four Star 40 (either kit or ARF) with no modifications or additions.
The controlling document for modification control will be the kit plans. Pilot
figures are allowed but optional.
A minimum of 2.75” wheels (as specified in the
plans) shall be used (larger wheels are acceptable given field conditions.)
These can be rubber, plastic or foam. No speed wheels (hub and O-ring) are
allowed. Wheel pants are NOT allowed.
The Thunder
Tiger 40 Pro with the stock muffler will be used for power. No muffler or
engine modifications are allowed. The engine will be installed (upright) as
per the plans.
Only the APC 9 X 6 (#APC-45) propellers will be used. No
modifications will be made to this prop other than balancing. Balancing
shall not alter the airfoil of the propeller.
Each airplane must have a 2”
spinner. Either plastic or aluminum is allowed.
The hosting club will supply fuel. Fuel will
contain 15% nitro-methane and can be of any manufacture.
Minimum aircraft weight will be 4.75 lbs (dry weight). This insures
that no hidden major structural modifications have been made.
