The Optipower Ultra-Guard is a simplistic back up solution for all types of model aircraft which operate off of any kind of receiver power; including BEC's and separate RX Batteries. Each aircraft costs hundreds if not thousands of dollars, and over time at any given point, solder connections can deteriorate, and electronics can fail. A failure of the receiver power surely would destroy any model, and leave the pilot with an upset short day at the flying field. 

Consider the Ultra-Guard an insurance policy for each of your models. Ultra-Guard is always there at the ready in the event of a voltage drop or even complete failure for your model! When plugged into any open port of the receiver, or flybarless gyro for helicopters, the Ultra-Guard is consistently monitoring input voltage, and as soon as the input voltage dips 0.5V below the original starting voltage, the Ultra-Guard is there for rescue! In a matter of milliseconds, the model is running off the backup 430mAh LiPo battery pack (at 0.5V less than input voltage), and has the ability to warn you with an external LED (optional; not required for use).

Features at a Glance:
  • A simplistic insurance policy for all model aircraft
  • Wide input voltage: 4.6V - 8.4V
  • 2s 430mAh charges each flight
  • Universal JR connectors utilized
  • JST-XH Balance connection used for LiPo & Main Board
  • LED system status
  • Storage charge function
  • 5A continuous current
  • 10A peak current
  • Vibration proof flexi board design
  • Assembled in Europe

The "Mega-Guard" includes every safety device included in one package! Which includes:
  • (1) Ultra-Guard
  • (1) Remote LED Module
  • (1) BEC Guard
The included BEC guard is an excellent choice for any model which is powered not only with a BEC, but as well as a LiPo batter. The BEC Guard serves as a filter and protection against back EMF current generated from servos, as well as over voltage protection sent back to the servos, receiver, and/or flybarless gyros.

Optipower Ultra-Guard "Mega Guard" Back Up Solution Mega Combo
I have been using this product for years. Cheap insurance against in-flight BEC failure. On a large 700 size heli, the cost and weight is worth the peace of mind. Works as advertised; never any issues.
