Topic Question Answer
12 My servo is not listed in the user guide. Which mode should I use? First of all please check if your servo is listed on our servo selection table by clicking [here]. The most reliable way of determining the...
90 The servo slightly moves when I switch between heading hold and rate mode, why? All trims are... This is normal functionality designed to allowing the gyro to accommodate rudder trim in rate mode.* Spartan RC products follow the Futaba...
85 Does the new 560Hz frame rate shorten the lifetime of the servos? Before implementing the 560Hz mode Spartan RC has studied the datasheets of the servo controller chips used in all popular 760uSec servos and...
77 I run my gyro and servo at 6V so the servo is faster than the preset value in the configuration... The pre-set values in the configuration software are provided for convenience. You can adjust the servo speed as needed, for example if your run your...
38 Is this servo compatible with my gyro? The ds760 and Quark gyros offer several servo drive modes to accommodate all digital servos on the market. We have included some of the most popular...
23 Using a voltage regulator or step-down. The ds760 and Quark gyros feed power the servo from the black rudder plug. The gyro itself gets powered from the red gain plug. If you want to use a...
19 The servo sometimes moves and sometimes does not. This is the typical symptom when using the wrong servo pulse modulation. Because the 760uS and 1520uS standards partly overlap the servo works in...
18 The servo is not moving. Check that the rudder and gain inputs of the gyro are plugged to the correct receiver outputs. Make sure that the correct servo type has been...
8 Which tail servo do you recommend for use with the Spartan gyros? To get the best performance from your Spartan gyro always use fast tail servos. Futaba S9254, S9256, BLS251 and JR 8900G work very well with our...
7 I plugged my servo to the gyro with the wrong servo type selected. It is damaged? As a general rule 1520uSec/333Hz capable servos will also happily run at 1520uSec/250Hz but not the other way round. In certain cases use of the...
1 Can you please explain what is frame rate and pulse width? The servo position is controlled by an electrical pulse or variable duration which in electronic terms is called pulse width. The pulse repeats at...
80 At what distance should I place the servo ball link? The best practice is to first try the advice in your helicopter's assembly manual. We recommend that you initially place the servo ball link at the...
13 Do the servo endpoints need to be equal? No, and this is why our gyros provide independent endpoint adjustment for each end. You should however try to avoid extreme difference (greater than...
102 The cable of my servo is much thicker than the cable of the Quark. Can I use this servo or the... The five thin wires entering the gyro are control signals and power supply for the gyro electronics only. The servo is not powered through these thin...
122 Will the ds760 or Quark work at all with analog servos? Sorry, neither of these gyros supports analogue servos. Analogue servos can not deliver the performance these gyros are designed for. To avoid...
