Remember, if the aircraft pitches up and stalls, trim the elevator control to add more down elevator. If the aircraft dives, trim the
elevator control to add more up elevator. Upon landing, make final adjustments to the flight control linkages until the correct flight
test results are obtained with the trims set at neutral.
ADDING EXPONENTIAL OR DUAL RATES
Although neither function is required to fly the RAZOR successfully, extensive flight testing by FMA engineers has determined that
handling characteristics can be dramatically improved with the addition of exponential or dual rates on the aileron and/or elevator
controls. Begin with 50% exponential and increase or decrease to match your tastes. If you do not have this capability, try setting
up dual rates. Use low rates (elevon throws of 3/8” each direction, up and down) for the initial flights during trim-out and then move
to high rates (1/2” or 3/4” throws) once you are familiar with the flight characteristics of the airplane.
FLIGHT CHARACTERISTICS
Overall, you will find the RAZOR to be a satisfying and enjoyable airplane to fly. The slope, park, and 400 Class models are extremely
docile and easy to manage. They can fly very slowly and do not readily approach stall speeds. The 600 Class models are designed
for high speed! They require a higher skill level and because of the weight, they should be maintained at an airspeed significantly
higher than 400 Class, especially in turns. As with any flying wing design, the one inherent trait to watch out for is tip stalling. If you
have successfully completed the instructions relating to limiting this phenomenon in STEPS 50 and 55, you will be pleased with the
600 Class slow speed flight characteristics and stall recovery, but please realize that because of the weight of this aircraft, tip stalls
cannot be completely eliminated. With either class of RAZOR, if you should ever push the aircraft to the point of stall, the tendency is
for it to stall at the tip and then begin to spiral. Should this happen, pull back on throttle, allow your control sticks to neutralize, and
let the airplane recover itself. At the bottom of one complete spiral, add throttle slowly, gently pull back on the stick and regain level
flight. Finally, on a 600 Class model, when the battery runs down and the motor shuts off, release elevator control, level out the
plane and maintain your airspeed on approach!
STORAGE INSTRUCTIONS
Never store your airplane inside of your car on a hot summer day. This could cause the structural tape to shrink and thereby create a
warp in the wings. If wing warpage or bowing should occur, remove the structural tape from the wings and install new tape as per
the instructions provided in this manual. Never attempt to fly the airplane with warped or bowed wings! Also be aware that during
extreme cold conditions the adhesive tape used in assembly may lose some of its bonding strength.
CONVERTING AIRPLANE MODELS
If you purchased the slope soar model of the RAZOR, and later wish to convert it over to a 400 Class model, purchase a 400 motor
pack and a 7 cell 600AE battery. Follow the instructions in this manual for installation. If you purchased the 600 Class “Endurance”
model and later wish to upgrade to a “Performance” model, purchase the “Performance” 600 motor, a male and a female Deans Ultra
pigtail. Install the motor and connectors as per the MOTOR PACK diagram on page 10.
In addition to the following spare parts list available by calling direct or through your local hobby dealer, FMA Direct stocks a full line
of receivers, servos, batteries, speed controllers, chargers, etc. For fast charging RAZOR battery power packs, FMA recommends
charger models FC300 “MINIPULSE” or FC600 “VERSAPULSE”.
