Setup Endpoints for Castle ESC and AR7200BX

Tom Hintz - 08/12/2014

Overview

Here is a procedure that will work to setup yourCastle ICE ESC with your Spektrum AR7200BX receiver, without using a separate power supply. This procedure was done with a DX7 radio, so make adjustments where needed for your radio. This procedure does not care if your equipment is brand new or well used, previously calibrated or not. It will work. This assumes you are running the Castle ICE in governor mode. You may or may not use Auto Rotate feature, that’s up to you. You may or may not like the Fail Safe feature, but it matters not. It is there, so you must deal with it. Follow this procedure step by step, and it will work every time.

Before you start remove your main and rotor blades

Steps

• Set Throttle Curve for ST-1 to (70,INH,70,INH,70)
• Set Throttle Curve for ST-2 to (100,INH,100,INH,100)
• Set Flight Mode to Norm
• Set Throttle Curve for Norm to linear (0,INH,50,INH,100)
• Adjust Travel Adjust for Throttle to H=0, L=0
• Battery unplugged
• Radio off
• Put Bind plug in Bind slot on AR7200BX
• Plug battery in
• Hold down Bind button on back of DX7
• Continue to hold down Bind button while turning on Radio
• Continue to hold down Bind button until flashing light on AR7200BX (or on satellite) turns solid (this light is down by the servo plugs)
• When light is solid, Bind is done
• Remove Bind plug
• Unplug battery
• Radio off
• Radio on
• Plug battery in
• Move throttle stick to High (full throttle, all the way up)
• Raise Travel Adjust H until the motor beeps
• Raise Travel Adjust H two more clicks
• Move throttle stick to Low (zero throttle, all the way down)
• Raise Travel Adjust L until the motor beeps
• Raise Travel Adjust L two more clicks
• ICE ESC is now calibrated for throttle
• Set Throttle Curve for Norm to (0,INH,0,INH,0)
• Flight Mode is still in Norm
• Unplug Battery
• Radio off
• Put Bind plug in Bind slot on AR7200BX
• Plug battery in
• Hold down Bind button on back of DX7
• Continue to hold down Bind button while turning on Radio
• Continue to hold down Bind button until flashing light on AR7200BX (or on satellite) turns solid (this light is down by the servo plugs)
• When light is solid, Bind is done
• Remove Bind plug
• Unplug battery
• Radio off
• Radio on
• If you are NOT using Auto Rotate feature, set Throttle Curve for Norm to (30,INH,30,INH,30)
• If you are NOT using Auto Rotate feature, set your Throttle Hold to 0
• If you are NOT using Auto Rotate, you are done

Everything after this step is only needed if you are using Auto Rotate feature

• Throttle Curve for Norm should still be set to (0,INH,0,INH,0)
• Flight Mode still in Norm
• Throttle Hold is OFF
• Set Throttle Hold to 0
• Plug in Battery
• Wait for ICE to initialize
• Throttle Hold ON
• Raise Throttle Hold setting until the heli starts to spool up
• Lower Throttle Hold setting until the heli stops
• Unplug Battery
• Radio off
• Put Bind plug in Bind slot on AR7200BX
• Plug battery in
• Flight Mode still in Norm
• Throttle Hold OFF
• Hold down Bind button on back of DX7
• Continue to hold down Bind button while turning on Radio, after turning on radio, immediately switch on Throttle Hold
• Continue to hold down Bind button until flashing light on AR7200BX (or on satellite) turns solid (this light is down by the servo plugs)
• This bind with Throttle Hold ensures that if you have a signal loss the AR7200BX will output your Throttle Hold setting and not your Low Throttle setting. That way when the signal comes back, the ICE will quickly spool up to speed again.
• When light is solid, Bind is done
• Remove Bind plug
• You’re are done
