ZTW A-ZTW40A 40 Amp S-BEC ESC

The ZTW 40 Amp speed controller features a switching battery eliminating circuit (SBEC)  allowing not only a higher operating Voltage, but the ability to operate over 4 servos reliably from the speed controllers BEC circuit. The ZTW 40 Amp controller would be the ideal ESC for E-flites Park 480 motor and the associated aircraft designed for this motor such as the E-flite Extra 260 3D 480 and Sukhoi SU-26M 480. We strongly recommend this controller for the Telink/GB Yak or the RC Factory Yak/Flash especially when digital servos are utilised. The ZTW 40 Amp controller would also be a low cost alternative to the popular Hacker X-40 SB Pro that is recommended for the SebArt range of aircraft using the Hacker A30-14L such as the SebArt Katana S30, Angel S or Shark. This controller is ideal for many other aircraft and helicopter applications that are operating four or more servos/gyro and require a really good controller with a SBEC circuit.

General features:

�  Extremely high rpm ability that can support virtually all the current brushless motors in the market
�  Super smooth and accurate linear acceleration
�  Safe start function
�  Protection from losing remote control signal
�  Over temperature protection automatically reduces power output at 110℃, until controller temperature recovers to below 110℃
�  Robust BEC circuits ability of driving servo, surpass all ESC in current market
�  Suitable for all types of brushless motors
�  Extensive programming functions

Programmable functions:

�  Brake setting
�  Battery type （Li-Po or Ni-MH/NiCad）
�  Cut-off voltage setting
�  Restore factory setting
�  Motor timing
�  Acceleration on start up (hard, soft, very soft)
�  Helicopter mode (for Helicopter models)
�   Motor direction (clockwise/counter clockwise)
�  Operation frequency
�  Low voltage cut-off type (slow down or shutdown immediately)

All ZTW speed controllers are supplied without an on/off switch. I feel this is a positive move and firstly eliminates the risk of accidently leaving the drive battery connected leading to irreversible damage to your Li-Po battery and secondly removes the need to fasten the switch securely to prevent accidental switch off.

All ZTW speed controllers feature the same programming. Programming can be accessed using either your transmitters stick or with the optional programme card that we would strongly recommend.

ZTW controllers are supplied without connectors but feature pre-tinned wires for easy soldering.

All controllers are supplied
