ParkAero were the first and original company in the UK to bring you the ZTW range of brushless speed controllers. In this time many flyers have now come to trust and depend on ZTW controllers for their latest projects. ZTW reliability and superb throttle response has won many friends. Added to the controllers operation is the price that can be described as extremely attractive. Gone are the days when you have to pay a fortune for the best latest technology.

All ZTW controllers offer a smooth and instant throttle response. The ZTW range is not just for aircraft as all controllers can be used in electric helicopter with a slow start and governor mode available if required. All controllers feature quality build and full programmability. The ZTW speed controller range offer the same extensive programming features on every version. This encompasses battery type, governor mode, very soft/soft and instant start, brake on/off, timing, motor direction/rotation, voltage cut-off 2.8/3.0/3.2V and soft/stop cut-off. All programming can be accomplished via your radio transmitters throttle stick by listening for the customary bleeps. Available separately but certainly not essential is the optional program card that can make reprogramming a far simpler operation. Remember, one card can be used on the entire range so there’s no need to purchase a separate card per controller. All ZTW controllers are Li-Po ready out the packet and most users will not find a need to program the esc before use.

BEC/Switching BEC (SBEC)

All the ZTW controllers feature a ‘Battery Eliminating Circuit’ (BEC) that is able to supply current to your receiver to operate the receiver and servos instead of a traditional separate receiver battery. Speed controller BEC circuits fall into two distinct types – the most widely used is a linear BEC that is used by most esc manufacturers. Due to the limitation of the linear type of circuit a new more advanced type of BEC circuit has been introduced into some of the more sophisticated controllers called a switching BEC or SBEC as it’s more widely known. Linear BEC circuits feature on all the 6, 12, 20, 30 Amp ZTW controllers. A linear BEC will drop the input voltage of the controller and supply current to the receiver. This process generates heat through the BEC circuit and limits the amount of servos that can be safely operated via the BEC circuit. Generally the higher the input voltage to the controller the less servos can be used. A switching BEC is a far more advanced circuit that is capable of supplying a higher current and constant voltage to your receiver and servos regardless of the input voltage to the controller. This makes servo numbers less critical and the risk of ‘brownout’ due to voltage drop-offs with 2.4GHz equipment far less likely. Obviously all controllers have a maximum voltage limit and this must be adhered too. All ZTW SBEC controllers can deliver 5.5 Volts and up to 4 Amps peak through the BEC circuit.

ZTW controllers are supplied without connectors to allow the user greater flexibility. Why pay for pre-fitted connectors if there not the type you use? ZTW are NOT fitted with an on/off switch and requires the flyer to connect and disconnect the flight battery before and after use – a good discipline.  

SPEKTRUM/JR - DSM2 2.4GHz Users

Spektrum/JR - DSM2 user may require a different process that stated in the manual to set-up their controller initially. If you have purchased a ZTW controller from us and are unable to set-up your controller please contact us for further information

Futaba/Hitec Users

Please remember to reverse the throttle channel from ‘Normal’ to ‘Reverse’ on your transmitter before attempting to operate your new ESC. Generally this is Channel 3 but can vary on the more sophisticated Futaba transmitters that allow the user to alter the channel assignments.
