Servos are the direct link between your stick movements and the control surfaces of your aircraft and can vary tremendously in their ability to translate this information accurately. There are many low cost servos available that are really just that – low cost, but their operation can sometimes be lacking. Poor centring and a wide dead band are often indicators and will lead to an aircraft that will never be accurate and respond to your command. We have been extremely careful with our selection of servos, and have ensured that they perform as we would expect. They may not be the very cheapest, but they are pretty competitive.

ParkAero Operating Tips:

When you have received your servo please resist the temptation to twist the servo arm by hand. This is a widely used and acknowledged method of stripping gears instantly. If you wish to test the servo safely out of your aircraft invest in a servo tester. A servo tester is a handy device for testing a servos operating action and most testers can be used for setting the servos centre point prior to installation.

As with all servos, we would recommend that the voltage of the receiver battery is tested prior to switching on. The latest generation of Ni-MH receiver packs can produce far in excess of the stated voltage when first charged. This excess voltage can kill your servo in milliseconds and we would advise that your pack is ‘rested’ before use to allow the peak voltage to subside.

Maximise your servos output torque by the careful use of mechanical advantage. Your servo produces its maximum torque using the shortest arm and closest hole to the centre servo screw. Long arms equal less torque, less holding power and increased transit time. When setting up your model try to avoid using your transmitter’s end point adjustments to reduce travel. If you need to reduce the travel, especially when using the longer arms so often specified on 3D models try to move surfaces pushrod down a hole further on the servo arm towards the centre. This will have the benefit of reducing the travel slightly; increasing the servos torque and transit time plus taking the strain of the servo - give it try.
