XPS X24 Integrated Flight Control System

INFORMATION UPDATED: 12/07/2018

To order this product, click here: http://www.xtremepowersystems.net/pr...?prod=XPS-X24D

We demo'd the X24 Channel Expander at the AMA show early this month. Many people have been asking about it, so I wanted to start a thread for information about it and so people could ask questions.

What does it do?

In short, everything! This device acts as a power expander (providing high current for your servos), replaces your switch system with a high current version, replaces your ignition battery (or BEC) with one built-in, replaces your match boxes, and can use up to 4 serial based receivers (SBUS, XBUS, etc.)... and more!


Some key features:
  • Dual 100A power inputs, controlled via a "soft" switch.
  • Programmable BEC with dual outputs for ignition systems, LED lighting, etc.
  • 4 receiver inputs, supporting 11 different serial protocols (XPS Xtreme, Spektrum, SBUS, SBUS2, XBUS Mode A, XBUS Mode B, Graupner SUMD, JETI UDI12, JETI UDI16, JETI ExBus, and Multiplex SLRX).
  • 4 Spektrum satellite inputs with a dedicated power supply for them.
  • 24 output ports, each individually programmable for the channel assignment, end points, neutral point, subtrim, reversing, and failsafe positions.
  • All 24 output ports have current sensing capability, meaning that you can see the current being drawn while manually matching channels.
  • AutoMatch (tm) - you setup a master servo and a slave servo, press a button, and the entire surface is matched for you electronically by building a 1536 point match curve, with 16x oversampling and 65536 step resolution! Don't settle for a handful of match points that other products give you!
  • 16 individual 3 stage sequencers (for gear doors, making pilots wave, or whatever you can dream up!)
  • Double-buffered servo outputs. Besides the normal current isolation, there is a buffer IC used to isolate the servo bus from the CPU. This offers protection for the CPU against a high voltage spike (like accidentally plugging in your 6S lipo instead of your 2S Lipo!) This also offers protection for the entire system in the event that a single servo shorts out.
  • Signal boosting. The output signal is not the normal 3.3v like all 2.4GHz receivers. Instead, the signal voltage is boosted to 5v and follows the input voltage when lower than 5v. This eliminates issues with certain servos that want to 'tick' when using a lipo for power and a 3.3v signal input. JR's retract servo also is one that requires a 5v signal.
  • Auxillary power input. Fully isolated 3rd power input. So, you could have both of the main power inputs fail and the 3rd input would still fly your plane.
  • OLED screen
  • Measures voltage and current 1000 times per second to show you REALLY what is going on.
  • Data logging of voltage, receiver packet loss, and more!
  • ..and much more!

The Pro version will be out later, and will include a complete flight stabilization system (3 axis gyro, 3 axis accelerometer, 3 axis magnetometer, and barometric pressure sensor). Units without this feature can be upgraded by us if you choose to do so at some point.

The manual for this product is available from our website:

there are lots of cool little details. like, the soft switch isn't just pin-flag capable, but to protect against a faulty switch you can tell it to only turn on or off by cycling the switch twice... the OLED screen is on a plug, so with a four-wire lead you can have it mounted remotely where you can see it, and read it without taking the canopy off, etc... remote status LED that will tell you more than whether the system has power or not... the matching doesn't have a limitation, you can match 11 sets of two servos, or one set of 22 servos.

it's going to be the power-expander to beat

where do I send my money?
this would go into my big compy 3.31 that's currently setup with dual recs and dual Smart fly's

Looks like a great product. Curious about how many amps can be supplied to all of the servos at one time and to each servo individually, continuous and spike or peak load.

Also, is it compatible with all popular high torque and high voltage servo brands? It seams like the new Futaba 7018 may be having problems with the MKS and newer Hitec servos. There may be an issue with excess voltage being fed back to receiver when control surface load is released with some servos. Do you have any concerns with X 24 compatability?

the X24 has 100amps per power circuit, two per input... so it's rated to 200amps continuous. Compare to other popular products for giant scale that max out at 30amps or whatever. You can have all your servos at their stall current and the X24 wont care.

The voltage is set by whatever you feed it (for HV, wire in some 2S lipos, for regular servos connect up LiFE, etc). X24 is not regulating the servo output; less things to go wrong, but also so people can go with direct-to-battery setups that can handle larger spikes and power demands.

I'll have to let Jim comment on handling voltage feedback from newer servos...

Wow, great capabilities! Looks like I've got some reading to do to catch up on Sbus and one of these expanders--any links to some reading materials for "Sbus for Dummies"?


My VERY basic understanding: Futaba Sbus rx single wire to this expander. Multiple servos matching/endpoints/reversing thru X24--say, 3 ailerons per wing, 2 elev per half, etc. Do you just use a standard dual ail/dual elev TX setup, or do you have to have multiple channels programmed/slaved in the TX? Sorry for asking here--just trying to catch up

your understanding already is pretty much all you need; SBus is just a serial "all information on one wire" protocol that devices like the X10/X24 make practical use of (X10 being XPS's first power expander which was crazy good even as it is).

And yes, with servo matching done in the X24, would be very easy to fly a 50%er with a simple 6 channel radio. Matching is done by setting up just one channel/servo as the master, and then the X24 will figure out the other servos as slaves. Means more setup can be done in the plane, which makes transmitter setup easier, transfer/copying models, buddy-box setups, etc.

Thanks for the reply! I was hoping it was that simple; I've stayed away from the Futaba Sbus stuff so far due to needing their servos and/or their Sbus adaptors, but this system looks sweet!

yup, that, and the Nano receiver (which are currently XtremeLink, but will have DMSS support soon)...

...but also any other receiver that can output a serial data stream; (all the futaba SBus receivers, the Spektrum and JR satellites, Jeti receivers, FrSky SBus receivers, etc etc). Works with so much gear it's kind of nutty.
