Reactor X2


The NEW Reactor X2 has been redesigned to include our most requested feature, direct unregulated voltage to the cyclic servos while maintaining safe, regulated 5.2v power to the receiver, gyro, tail servo and other sensitive equipment.

As the unfailing heart of your helicopter. The Reactor X2 generates noticeable servo power, which provides consistency and agility for both 3D and F3C flight. Providing power to the servos and receiver on dual power bus voltage regulators, the Reactor X2 is one of the first of its kind to provide split power output and servo bus technology to the R/C heli market.

A lot is riding on the power system of any r/c heli, don’t trust anything less than Reactor X2… the old saying is true - you get what you pay for.

New X2 Features

We’ve added what customers wanted to the popular, proven, and high quality ReactorX regulator.

Three selectable voltage settings of the CCPM servo bus (regulated 6.0V, regulated 6.4V, NEW unregulated 8.4V)

Supports over 15 Amps of continuous output for use with any servos on the market.

The preset CCPM voltages are: 6.0V regulated for all standard and digital servos. 6.8V regulated for high voltage type servos and brushless series servos. In addition the new X2 now allows full unregulated Li-Po voltage (8.4V at full charge) to pass directly to the servos for maximum voltage to HV type servos.

Reactor X2 allows pilots to use HV servos on any type of receiver that normally would not allow direct Li-Po power supply. Certain Futaba, JR and other receivers do not permit direct Li-Po input voltage but can now be used with Reactor X2 by passing high voltage directly to the CCPM servos and a safe 5.2V to the receiver.

Dual Power Bus, Dual Regulators

The original Reactor X was the first helicopter voltage regulator system to offer dual regulators with servo power bus connections. The challenge of any power system is to supply current to hard-working servos safely and with the lowest resistance possible. Single battery setups with undersize wires and connectors don’t cut it anymore. Reactor X and the NEW Reactor X2 solves the power supply issue.

CCPM Power Bus - Three heavy current users CCPM / Mech. Mix servos are connected to the dedicated power bus for direct, consistent regulated power straight from the battery pack. A flick of a switch sets this power bus to 6.0V or an ultra powerful 6.8V output or use the included jumper for unregulated 8.4V, Futaba BLS Brushless heli servo series will find the 6.8V setting just as fast as unregulated 7.4V setups, but more consistent feel flight to flight.

Receiver Power Bus - A dedicated noise-free linear regulator provides preset 5.2V power through three redundant leads to your receiver which provides over 5 Amps of current. This voltage is recommended to get the best out of every gyro and tail rotor servo. The steady power supply will eliminate any chance of receiver brown-outs. Signal output from the RX to the CCPM servo bus are carried through the included large gauge connection leads. The receiver is at safe voltage for any 4.8V rated equipment plugged in.

Got Flybarless? Get Reactor X2

If you have a flybarless system, then you absolutely need a Reactor X2. No other regulator keeps sensitive flybarless systems safe like the Reactor X2.

Nothing could be simplier to hook up… just plug the the the Reactor X2 ports RX1, RX2 & RX3 ports into the flybarless sytems Aileron Servo Right, Aileron Servo Left and Elevator ports on the flybarless system, Everything else hooks up exactly the same,

By running a Reactor X2, only 5.2V of regulated power is transmitted to the flybarless system, protecting the electronics from dips and spikes as battery voltage changes in flight, So pick the Reactor X2, when you no longer have flybars.

Quality First

Reactor X2 is not your average “shrink-wrapped” voltage regulator. Enclosed in a custom case, this power system is protected better from the elements and harsh environments of R/C helicopters.With details such as built-in fast charge lead, horizontal connector headers for more compact wiring and preset voltages make this the most user friendly plug-and-play system.

The electronics are professionally designed to be noise free, RF interference free, and contain the highest quality components available. All Reactor X2’s are factory tested and backed by the best warranty in the business. We guarantee it.

Servos, setup and radio equipment only go so far. The last piece of the puzzle lies in the power system. All the equipment needing power from the battery works better, faster and more consistent on Reactor X2.

Whether you prefer “direct li-po” power for the ultimate in speed, torque and peformace while still maintaining safe voltage for receivers, gyros and other equipment the Reactor X2 does it.

And for those that prefer the consistent flight to flight feel of regulated power the Reactor X2 does it too. With the user selectable, 6.0V or 6.8V, the Reactor X2 ensures consistent performance, whether the battery is 100% or 30% charged. The Reactor X2’s 6.8V power setting will match any direct voltage performance, without feeling any voltage dips encountered during high current extreme flight.
