The smart choice for those who want more.

Everything that has to do with your landing gear, controlled by one device only. The SmartBox allows full control over your retracts and gear doors. If you want it all, this is your choice.

Compatible with ER-30, ER-40, ER-50 retracts (eVo, Classic & NG); brakes and servo motors / linear actuators for gear doors.

  • INTUITIVE  COLOR TOUCH SCREEN: Setting up your landing gear has never been easier. Navigate through comprehensive and colorful menus with the touchscreen to configure and adjust your system to suit your needs.
  • GYRO ASSIST & SPECIAL BRAKING:  Set up the integrated gyro to assist on takeoff and then straight braking on landing, as well as optionally use the different ABS settings.
  • GEAR SEQUENCER: Our powerful sequencer allows you to set up the retract and door sequence with full control over all aspects. The timings for door opening and closing can be adjusted individually for each of the 8 protected door outputs, adding 50 sequencer steps; your imagination is the limit!
  • COMPATIBILITY GUARANTEED:  Electronics evolve, and so do working voltages. And that is why the SmartBox has two battery inputs. If your door servos need a voltage different from your retract, you can use a second battery just for them.
  • ALWAYS UP TO DATE:  With the Electron Retracts desktop App, you can easily update your controller with the latest firmware and newest features.


FAQ SMARTBOX

RETRACTS
  • Can I use a 2S battery with ER-50 NG retracts?

ER-50 NG retracts are rated for 3S LiPo voltage. Therefore, the battery that you have to connect to the retract unit controller should be a 3S battery.

With a 2S battery, the ER-50 NG retracts will work, but the speed and torque of the retraction will be reduced. Depending on the length and weight of the strut and the wheel, and other factors, the performance of the retract with a 2S battery could be enough to operate properly.

  • What retracts can be upgraded to a square thread SPINDLE?

All retracts purchased from January 2013. The serial number must start with 13, 14, 15, 16, etc (the first two digits indicate the manufacturing year)

  • Can I REVERSE the retract trunion, or change the RETRACTION ANGLE?

This is possible only in the “reversible version” of our retracts, released from January 2015 onwards. The indicative “reversible” is engraved next to the serial number.

  • What battery can I use with my retracts?

Electron suggests using a single small battery for retracts and brakes, and don't share the receiver or engine battery.

500-900 mAh will be enough for at least 25 flights, so with a very small battery, you will have enough power for a full flying day.

Wheels & Brakes

The BRAKES don't have enough POWER to stop my plane in the desired distance

Voltage increase: The last software for ER-30 and ER-40 allows for an increase in the voltage up to 13V (not for ER-50). With 3S LiPo, it is possible to increase the brake torque a little. Old control units can be updated with the new software: (contact us). Is possible to test the controller with a 3S LiPo to know if this controller accepts 13V. If not, the retracts simply will not run; nothing should burn. The ER-50 is limited to 10V for security, so only mechanical adjustments are possible.

Great Little Book
Format: Paperback
The title of this book purports to explain to us how sanctification works in the life of a believer. Most people, in American culture at least, will look at this title and expect something of a "how-to" book, filled with bullet points and flowcharts and methods. But Powlison surprises readers by not pinpointing one way of sanctification or one method of growth in holiness but providing instead a broad range of ways God works to grow us into Christlikeness. Powlison is at his best here: succinct, personal, practical and powerful. This book is written as a counter to the "one way of sanctification" teaching we sometimes hear today. For example, some teach all we need to do to be sanctified is to focus on the gospel, rehearse it to ourselves, remember it. Others teach that sanctification comes through spiritual disciplines. But Powlison says there are a variety of ways God changes us and we need them all at different times. Powlison's teaching about Truth Unbalanced and Rebalanced in chapter 3 is worth the price of the book alone. God blessed me through this book. Thank you David Powlison for sharing God's sanctifying work in your life with us.

Well Written
Format: Paperback
A personal account of the author’s suffering paired with other important experiences and Biblical truths. Theologically sound and a quick read. It was not what I was looking for but it was well written, nonetheless.

Wonderful Little Book
Format: Paperback
I actually really love this book. It's short and to the point which takes away a little bit of the theological clutter that you can find in a text book which does limit its content. However, the few points it addresses, lovingly points out incredible truth that we need to hear when helping others, and provides stories which demonstrates his point. The most important passage, in my opinion is, "Ministry 'unbalances' truth for the sake of relevance; theology 'rebalances' truth for the sake of comprehensiveness." (pg.33) Sometimes we want to help people with phrases like, "the lord gives and the lord takes away" or "rejoice always" which is a true fact but could be a dagger in the heart of someone who just lost a wife/husband/child and is breaking down. Either of those statements could calm someone with grief but could also cause anger and bitterness. Some truth can provide immense hope to those in need, but not all truths will help each person the same way and they might respond poorly in a situation of pain. We do a disservice when we assume that all people need the same answers in the same way.

Solid and Helpful but left me wishing for a little more
Format: Paperback
I loved the first 8 chapters - the last three fizzled out for me. It makes me wonder if even the first eight chapters could've been abridged and the whole thing reduced to a pithy booklet. That being said, the first eight chapters contain some excellent material that I will be incorporating not only into my own life, but into my toolbox of material to use in helping others. The best material for me was in: > Ch. 6, "What Changes You?" - He has a simple, practical grid of the basic "Five Factors of Sanctification." - Foundationally, God changes you. - Secondly, The Word of Truth changes you. - Third, Wise People change you. - Fourth, Suffering and Struggling changes you. - Finally, You change. "Constructive change occurs through the interplay of these five factors: God, Scripture, other People, Life Circumstances, and the Human Heart." "Foolishness either overcomplicates or oversimplifies." > Ch. 2, "Is there One Key to Sanctification?" This is his great critique of the idea that there's a master-key to the Christian life, some fool-proof, secret principle that changes everything for everyone. We tend to think that the thing that revolutionizes everything for me, must be "the key" for everyone. But we're too complex and the Word and life is too diverse for there to be one master key solution. "Theological fads and fashions come and go" - but part of the counsel of God was never intended to give us the benefits of "the whole counsel of God." New days come and new challenges arise, and we have to keep on pressing on. Our variety of needs and the varieties of helps necessarily defy "reductionism." There is no single key. "Progressive sanctification is about how we live in between God's laying the cornerstone and setting the capstone." > Ch. 3, "Truth Unbalanced and Rebalancing" - If I might reword David's principle, slightly, In ministry, we over-emphasize one aspect of truth for the sake of application. In David's words, "Ministry unbalances truth for the sake of relevance; theology rebalances truth for the sake of comprehensiveness." We can only say one thing at a time and a person, practically, can only work on one thing at a time. So we make much of a single thing, and then always try to bring it back into alignment with the whole of life and the whole counsel of God. "You do not build a house with only one tool in your toolbox when God gives you a truckload of tools. But you use your tools one at a time, the right tool for the right job." "In the long run, a single truth harped on will disappoint even its devotees." > 5. "We Are Sanctified By Remembering Our Justification." Throughout the book, David Powlison has been coming back to the concrete, recent example of a sanctification key, advocated by many: Remember the past grace of justification; Repreach the gospel to yourself every day; Realize that you are accepted by God because of the merits of Christ, not your own. In this chapter he highlights that this is certainly one of the tools in our toolbox - sometimes this is the very thing we need for progress in sanctification. But it is but one part of a larger whole. A greater point to always have in mind is that God is for us: He was, is, still is, and always will be for us. Don't just look to past grace, but also to present grace and future grace, as well as many other useful motivations. David's personal testimonies in chapters 7 and 8 are rich. He weaves in the interplay of the five agents of change. Very good. "There is a reason that 'Don't be afraid" (in all its variants) is the most common command in all of Scripture." There is also a beautiful section in the last chapter describing the contrast between the peace of the believer exemplified in a text like Psalm 23, and the "anti-psalm" emptiness of the unbeliever whose life ends at the end of the valley of the shadow of death. Very good, but a bit disappointing to me. Powlison is true physician of the soul. When he speaks I want to listen. I would recommend Kevin DeYoung's, "The Hole in Our Holiness: Filling the Gap between Gospel Passion and the Pursuit of Godliness" as an additional and very satisfying book on this subject.
