TEST FLYING THE MODEL
There is nothing exeptional on test ying this model, but never try to test y with the motor switched off!
1. Check the CG position, the control surfaces throws and the function of the motor. Because of the higher wing loading it is a good idea to ask a colleague
to launch the model for you.
2. Switch the motor on and launch the model with a powerful swing, approximately 40 degrees up, always against the wind.
3. Once in level ight, trim the model according to your requirements.
4. Because of the higher wing loading, always mind the minimum speed during the landing maneuvres.
The kit is not suitable for the beginners, an experience and continous attention are required for successful ying!
Have a lot of fun and many happy landings with the Cheetah kit!
