Important:
- The Purrz.75 is not a beginner FPV model. Make sure you are an
ace on a styrofoam airplane model before you fly this fast wing
for the first time.
- The heat resistance of the Purrz.75 is 60°C.
- Make sure all the components are tightly secured inside the
Fuselage (we use velcro tape).
Remember: A bungee start can produce as much as 10 G!
Anything moving around is changing the center of gravity.
- Back in the days they said: "flying means landing safely".
So know your landing strip.
- We recommend for the bungee start a start position of the
elevator of 1 mm to 1,5 mm up. In total make sure you will never
exceed 2,5 mm elevator up (from neutral position) otherwise u
might stall the Purrz.75.
Attach the hook to the Purrz.75 – did you put it in the right hole?
Hold the aircraft firmly at the frame right at the motor mount,
wings parallel to the ground. Then walk away backwards from the
stake approx. 10 meters. Now you are standing approx. 33m away
from the stake. Start in the direction of the wind if there is any. Now you are ready for take off. Hold the tension
(approx. 35 Newton) and swing the aircraft up and down in a big motion (2' up and 2' down) a few times. Let go while in an
upward swing and after release from the hook floor it. Have fun!!! (Check out our starts on www.flypurrz.de).
shorten the bungee kit because this will make it really hard to start.
