= What pitch is useful for my helicopter? = <!--T:6-->
In general you can say "the smaller the helicopter, the more pitch you have to set". But it also depends on how much motor power you helicopter has, the type of rotorblades you use and finally in what you expect to do with the helicopter. So beginner or scale pilots will not need as much pitch as a 3D aerobatics pilot or high speed flyer. Anyhow, as already mentioned above set the pitch range in MICROBEAST PLUS so that it roughly fits to your helicopter mechanics and its capabilities.<br />

= Measuring pitch without pitch gauge=
If your helicopter is too small for attaching a digital pitch gauge or simply in case you haven't got one you can use a little trick to measure the pitch anyway. You can calculate the angle from the distance the rotor blades move from zero position. Actually this is not as accurate as measuring the pitch with a digital pitch gauge, but it's better than nothing. All you need for this is a ruler and and a good eye. First you need to know the length of the rotorblades from the bolt hole to the outer edge. Usually this matches the specified rotor blade length of the manufacturer. Then you align the rotorhead with the longitudinal axis of the helicopter and fold both rotorblades to one side (as this will put heavy load on the servos it is not recommended use this method on large helicopters with heavy blades!). Now hold your ruler to the blades and mark the zero position. Then when you add positive or negative pitch you can measure the distance between the outer edge of one blade to the other. This distance can be transfered into degrees of blade pitch using the mathematical formula of sinus. Or the other way round you can calculate how far you rotorblades must move away from each other in order to get a specific blade pitch.<br />
