Precision Aerobatics Quantum 70A programmable ESC with Switching BEC


$40 (OBO) Going down $5 a day till it sells

New In Box, never used, just doing a little spring cleaning.

From Manufacturer:
PA Quantum Pro line feature outstanding quality backed by equally outstanding service since 2003.
The Quantum Pro range has developed over the years and has proven to be reliable and efficient.

The PA Quantum Pro line has a powerful switching voltage regulator chip which supports the high torque micro servos in the most demanding load-conditions imposed during aggressive 3D aerobatics, providing bulletproof reliability. In this form of flying the servos actuating oversized control surfaces and may stall momentarily under extreme aerodynamic loads. These loads may cause most low and medium power BECs to overheat and shutdown resulting in catastrophic loss of control. The Quantum Pro ESCís high power SBEC has been specifically designed for extreme aerobatics and therefore has the capability to support the higher momentary peak loads to eliminate the possibility of unwanted shutdowns. This high power SBEC is also capable of supporting continuous simultaneous multiple servo operations typically found in CCPM equipped hardcore 3D E-helicopters. The higher and stable SBEC voltage also reduces the possibility of receiver brownouts that occasionally occur on some 2.4GHz receivers in instances where conventional linear BECs are subjected to high servo loads causing the BEC voltage to drop below the voltage threshold required by the 2.4GHz receiver.


Features:
  • Extremely low internal resistance
  • Super smooth and accurate throttle linearity
  • Safety thermal over-load protection
  • Supports high RPM motors
  • Powerful and reliable switching BEC (Battery Eliminator Circuit)
  • New large high efficiency designed heat sink
  • Safety automatic throttle shut down in signal lose situation
  • Power arming protection (prevents the motor from accidentally running when switched ON)
  • NEW advanced programming software
  • Our ESC allows you to program all functions to fit your specific needs, which makes it very
    efficient and user friendly:

1. User programmable brake setting (we recommend using brake only for folding props applications)
2. User programmable battery type (LiPo or NiCd/NiMh)
3. User programmable low voltage cutoff setting
4. User programmable factory default setup restore
5. User programmable switching frequency
6. User programmable Low Voltage Cutoff type - LVC (power reduction or immediate shutdown)
7. User programmable timing settings (to enhance ESC efficiency and smoothness)
8. User programmable soft acceleration start ups (for delicate gearbox and helicopter applications)
9. User programmable motor rotation (clockwisecounterclockwise)
10. User programmable governor mode (for helicopter applications)
