Large Scale Airplane And UAV ZTW Backup Capacitor 60F 6V-8.4V 25A

ZTW Backup Capacitor 60F 6V-8.4V 25A High-Capacity Receiver Power Backup for Large RC Helicopter, Scale Airplane and UAV

60 Farad for Extended Backup Time

With more than double the capacitance of the 25F, the 60F provides significantly longer backup runtime — up to 60 seconds or more depending on servo load — giving pilots of large, complex models ample time to autorotate, glide, or execute a controlled descent.

Automatic Power Takeover

The capacitor bank instantly bridges any BEC dropout, battery failure, or wiring fault, maintaining uninterrupted power to the receiver, gyros, and servos so control is never lost at a critical moment.

6V-8.4V for HV 2S Systems

Rated for 6V to 8.4V input (max 9V), matching 2S LiFe/LiHV and 7.4V/8.4V high-voltage BEC setups on 550-800 class helicopters and large-scale airplanes.

25A Servo Current Handling

Delivers up to 25A instantaneous output to cover simultaneous high-torque servo draws on models with multiple large digital servos, such as scale warbirds with retracts and flaps or aerobatic helicopters.

Switch or Throttle Activation

The orange signal wire supports manual switch arming or automatic throttle-signal detection (50-600Hz), giving pilots a choice of fail-safe activation logic.

Built for Large Models

At 60×50×23mm and 60g, the 60F is sized for large airframes where the extra weight is negligible but the extended backup time is essential. The 60-core JR lead handles high servo currents.

Mission-Critical Redundancy

For professional UAVs, aerial photography platforms, and industrial rotorcraft carrying expensive payloads, the 60F provides a substantial power buffer against BEC failure — protecting both the airframe and the equipment it carries.
