Under the following conditions, your FP Aircraft will not fly:
1) Fabric not sealed properly.
2) C.G. out of limits foreward (noseheavy), or aft (tailheavy).
3)
Insufficient thrust from engine/prop combination.

These recommendations are made in an attempt to avoid any more of these incidents.
1)
Be certain the fabric is sealed on your aircraft before the
first test flight. This is accomplished by placing the lips against the fabric and attempting to draw air through the fabric. If air flows easily through fabric by this method, the fabric is not sealed, and the aircraft will not fly pro- perly.
2)
Do not attempt to fly a new aircraft without determining
that the actual balance point is within the prescribed C.G. range.
3)
Do not attempt to fly with an engine/prop combination which
is not producing the necessary thrust. Several engines are available which are capable of flying these aircraft. Before making a choice, the builder must know what the engine weighs and what thrust it will produce. Fisher Flying Products specifically does not recommend the Global engine be installed on our aircraft.
4)
Do not attempt to fly this aircraft with cowling removed,
since the exposed firewall greatly increases frontal area, and thus, drag and stall speed, in addition to disturbing airflow over the fuselage and tail surfaces.
5)
Most important of all - Use Common Sense! ! On initial test
flights, if more than 150-200 ft. of runway is used and the aircraft is not airborne and climbing, abort the take-off and find out why!! Never force this or any aircraft to fly. If more than a slight back pressure on the stick is required to break ground and climb, the aircraft is not going to fly, and attempting to force it to do so is inviting a stall and crash!!

Please address any questions concerning this bulletin to me at Fisher Flying Products, Inc.
