Product Description
The Vertex V17R is a compact 17A brushless speed controller developed for lightweight EPP aircraft. It operates as a conventional forward-only ESC for traditional 3D flying and can also provide transmitter-controlled forward and reverse thrust for advanced 4D flight. Factory-programmed BLHeli_S firmware, a powerful 6V / 3A switching BEC, and pre-installed connectors provide responsive motor control with straightforward installation.
V17R ESC Overview
3D / 4D Reversible ESC
Operating Modes
Forward / Reversible
Burst Current
25A / 10 Seconds
Switchable 3D and 4D Operation
Use the V17R as a standard forward-only ESC or configure reverse thrust through a compatible programmable transmitter. No physical reversing switch is required on the ESC. Reversible operation also requires a compatible motor and 4D propeller.

No Low-Voltage Cutoff: The V17R does not provide low-voltage cutoff protection. Use a flight timer and monitor battery voltage to prevent excessive LiPo discharge.
Important Initial Setup: The transmitter’s throttle range must be calibrated before the ESC will arm and operate correctly.
Programming Information: The V17R arrives factory programmed for its intended 3D and 4D operation. An optional USB programming kit is available for experienced users. Custom software, third-party firmware, and unsupported setting changes may affect performance or reliability and are not supported by Twisted Hobbys.
