RPM there is 0 timing Boost Angle this number is given in degrees per 1000RPM so for each RPM increase of your motor by 1000 the speed control will increase it s dynamic timing by the set value until the set Boost Timing has been reached Higher number means more aggressive timing engagement as higher timing is reached at lower RPM also higher number will usually increase motor temperature Turbo Timing only enabled for stock profiles 6 10 Applies 10 of extra turbo timing when set Boost Ti ming level has been reached you apply full throttle on the radio Important be aware that settings need to match your motor well In case you use a low rpm motor and a high boost value it is possble that the final Boost Timing can not be achieved with a low Boost Angle value and therefore speed might not be as imagined or Turbo Timing might never engage ROV Viode 4 Automatic Brake flash alternativel Remark Brake strength allows you to set a slight braking action when your trigger is in neutral range Special Features further explanations Boost0 Racing the blue MODE LED will flash in neutral trigger position to indisate that entire timing advance ment is disabled for true stock racing as required by certain federations Boost0 is enabled with following Mode2 Mode3 combinations Mode 2 6 7 8 9 or 10 Mode 3 0 Linear BEC a powerful linear 6V 3A output has been inte
