MODE PROGRAMMING
Power Profiles: the SPX Zero is not designed as a „highpower“ stock speed-control but for true stock racing
withequalspeeds.Neverthelessit‘sversatileformanyracingclasses,motorsandpersonaldriverpreferences!
Dependingonthestatusofthecar(start,acceleration,fullspeed)thesoftwarecalculatestheperfectmotormanagement.
Higher profiles mean more overall power and aggressive response.
Profiles 1-3aremeantformildmodifiedmotorsand4+5aremildstockprofiles, asknownfromprovenSphere

The great„Boost 0“ mode,for truestockracingwith equal power can easilyberecognisedwhentheredLED
flashes in neutral position in normal operation to indicate that entire timing advancement is disabled!
AutoCell System:LRP’sexclusiveandsmartAutoCellSystemensuresthatLiPobatteriescanbeusedsafely
without accidentially deep-discharging of the cells. The motor function will be shut-off and the SET LED will flash
if the system recognises very low battery voltage.
Internal-Temp-Check System: the SPX Zeroallowsyoutoread-outthemaximuminternaltemperaturethat
thespeedoreached.Tostoreittothememory,brieflyapplybrakesaftertherunbeforeyouturntheswitchoff.You
canconvienentlyread-outthetemperaturebackinthepitssinceitremainsstoreduntilyouturnitonthenexttime
regularly (which will reset the memory). This new feature allows you to accurately check if all is running well or if
you‘reclosetoshutdownalready.
How to read-out the temperature:
 Switch at „OFF“ position.
 Keep MODE button pressed while you turn switch to „ON“ (then release button)
 SETLEDwillstarttoflashred(MODELEDisoff),nowcountthenumberofflashes.
Basics:
•Thermalshutdownofthespeedowouldoccurat5flashes.
•Thehigherthenumberofflashes,thecoolerthespeedoran(e.g.thebetteritis!)
•Everyflashequalsto~8°Ctemperaturedecrease
Example:
 you count 10 flashes after the run
 10 - 5 = 5 (e.g. 5 flashes „away“ from shutdown)
 5x8°C=40°C(e.g.youare40°Cawayfromthermalshutdownandthereforesafe!)
Brake: superlinear feeling with a strong pushbrake and 6 fine steps for almost infinite adjustments of autobrake!
Team advise: Agoodstartingpointforthebrakesettingonyourradiois80%forallclasses.Makesureyoudothe
radio-setupwithallsettingsontheradioon100%!
Changing Mode settings without the transmitter: At race events you usually do not have access to your
transmitter,butnevermindsinceyoucansimplydisconnectthereceiverleadfromthereceiverandchangethe
MODE settings as described at „Mode Programming“.
Works-Default-Settings: All LRP speed-controls come factory-adjusted (defaults are grey-shaded above).
Ifyouloosetrackofthe modes,you canrestoretheworks default settings.With thetransmitterswitchedon,
hold the SET button pressed while you switch on the speed-control. This returns the unit to the LRP works default
settings.
Pure Brushless Forward/Brake Design: uncompromising and outstanding performance for top level com-
petition was the target for the SPX Zero! Therefore the LRP engineering team developed a pure forward/brake
brushless speed-control. There is no reverse function and no brushed operation.
Power Capacitor: Neverrunwithoutapower-capacitor!Itoffersincreasedpunchandadditionalprotection,
Multi-Protection System: Theperfectprotectionagainstshort-circuits (motor), overload andoverheating.
Ifyourspeed-controlfacesoverload,themotorfunctionwillbeshut-offforprotectionandtheSETLEDwillflash,
althoughthesteeringfunctionismaintained.Letthespeed-controlcooldownforafewminutes.Ifyouexperience
frequentshutdowns,checkforthefollowing:
•Correctgearratio(refertomotormanualforgearingrecommendations)
•Powerprofilesettingtoohigh(highervaluewillheatupmotorandspeed-controlexcessively)
•Motoristoostrongormotorisdamaged.

The SPX Zero features 4modes whichenableyoutoadjustit100%toYOURspecialrequirements. Thefactory
settings are shown in grey colour.
MODE.1 (AutoCell System): werecommendusing value2forracingpurposeswithcellsother then 2S/7.4V
LiPo,whichdisablesthecut-offfunctioncompletely.

Cut-Off
Caution:themostcommonreasonfor„unexpected“shutdownisusingthewrongvalueinthismode!
MODE.2 (Power Profiles): this mode contains the new „Boost 0“ which is meant for true stock racing with
brushless motors and no added speed-control timing and which is indicated by the flashing red LED in normal
driving mode (when throttle is in neutral).
Additionally the SPX Zero incorporates further profiles so you can adjust the feel to your likes. Either you run On-
RoadorOffRoad,onslipperyorhigh-tractionsurfaces,wehaveincorporatedaprofileforyou!Highervaluemeans
more aggressive throttle response.
MODE.3 (Initial Brake): Allows you to set a certain level of „hand-brake-effect“.
MODE.4 (Automatic Brake): called auto- or drag-brake. This function allows you to set a slight braking action
which is applied in the neutral range.
