User manual CASTLE CREATIONS CASTLE LINK

[. . . ] As a result, Castle must offer the following modes to accommodate the different transmitters in use. Auto calibrating is primarily for gliders; Airplane Fixed Endpoint is for most fixed wing power planes. Governor mode(s) (Low and High) is for collective pitch helicopters when you want a fixed head-speed throughout the collective range. Helicopter Fixed Endpoint is for fixed pitch helicopters and collective pitch helicopters when a manually set throttle and pitch curve is used on the transmitter. Issue Date 5/18/2006 Page 1 SETTING EXPLANATION Airplane: Auto Calibrating: (Airplanes). [. . . ] When this throttle mode is selected, the Phoenix will automatically maintain your helicopter's head-speed at an RPM that is determined by the throttle signal. Once you determine the throttle % that gives the head speed you want, your throttle curve should be programmed to be "flat" at that percentage setting (all throttle points set to that throttle %). The following settings must be made in your transmitter's program; typically one three position switch is used to toggle between the settings: 1. Phoenix must see a zero or bottom throttle setting to arm, so set one flight mode or switch to provide that signal. Then set up a second flight mode or switch setting that will be your "throttle up" switch. Determine the necessary throttle % for your desired head-speed. Start with a flat curve in low governor and measure the head-speed. Move the throttle % up or down to reach your desired head-speed. If you cannot get a fast enough head-speed in low gov, then switch to high gov. When you find the throttle % that produces your desired head-speed, set all the throttle points to that % and the Phoenix will maintain that constant head-speed as long as your transmitter is sending that throttle percentage. It is not advisable to change throttle speed with the transmitter while in governor mode, with the obvious exception of on and off. · Governor Mode general notes: 1. When using Heli Governor Mode, allow the Phoenix governor to control the spool up of your heli. Trying to control spool up by gradually increasing the throttle can lead to abrupt power changes. It is best to use a switch for startup that goes from zero throttle directly to your required throttle setting when flipped. The Phoenix governor will take it from there. When using Governor Mode always set `Throttle Response' to Low. Governor Auto Rotation with Bail-Out Mode (Idle/flight mode) You want to keep the ESC from resetting and going to governed spool up by not going to OFF throttle. Set idle 3 to a low flat throttle curve that keeps the motor running slowly. Now drop the throttle curve down slowly until the motor stops running. Bring the throttle % back up a few points until it begins running again. That setting will be your minimum throttle % to keep the ESC from resetting by going to `Off Throttle. ' Your motor will throttle down to your lowest speed setting that will not affect the autorotation, while preventing the ESC from resetting and going to governor controlled slow spool up.
