IMPORTANT: Using an incorrect controller type will damage your Electron retracts and void the warranty. It is the customer's responsibility to ensure the correct retract controller type is selected. Please contact Electron at:  [email protected] and provide your retract serial number to ensure you select the correct type.  

 

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.

The best!
UPDATE: 08/05/2025 - This is still one of my dog's 2 fav training/play toys. A couple of notes: 1. This is not a chew toy. If your pup is chewing up the rope, that's on you. That being said, you can get 100' of the poly cord rope at Home Depot for like $4.98. You can make nearly 100 ropes out of 100'. How hard is it to replace the rope????? 2. My pup is a now 15 month old Malinois. His original balls, purchase in September 2024 are still in everyday, multiple times per day, play. I did get careless and leave one where he got it and chew the rope. Easily replaced. Nothing to fret over. Yes, that was on me! 3.The foam ball is virtually indestructible! Replace the rope! 4. I noticed the price for the yellow large went from $12 each to $24. THIS will cause me to go elsewhere if they doubled in price. I LOVE these balls but not that much. I noticed they have a new yellow ball that has a strap vs. a rope. I might try that if I need one, but I have 6 of these balls, 2 never used yet, 2 that are virtually new looking, and 2 that have been in play since september 2024. I don't think I'll be buying more any time soon, but if I do need more, I hope they haven't gone up to $24 each. One of my top, go-to training tools. Quality is great other than the shrink wrap around the string joint. It's junk but not essential. Great tug and fetch toy. Essential to teaching a good "out" command (2 are recommended for this).

Best dog ball
This is our go to dog toy for our German shepherd. its great for training in sports as well as outings at the beach, considering it floats! Never had him destroy one, so its extremely durable. I like that its a bright color so its easier to locate when i accidently let go of the rope too late and end up whipping it 20 ft into the woods. Easy to clean, all around just a great toy. Also love the large size as having a dog accidently lodge a ball into its throat is a real fear of mine, I do not have to worry about that with this toy. I should also mention the rope is a must, as touching a slobbery ball isn't the greatest feeling in the world and it puts your hands out of harms way. I will forever order these.

Great ball, bad rope
Size: Medium, Number of Items: 1, Size: Medium, Number of Items: 1
My dog and I love the starmark ball on a rope tug toys. While this is one of the best tug toys we have found, I am continually disappointed with the quality of the rope. The plastic sleeve comes off the first day, and after that the stitching begins to weaken until the rope ends come apart and the rope slides out of the ball. Is there a way to improve this design so that this toy lasts longer? My dog is not left alone with the toy, it is only used as an interactive tug toy as a training reward. I am updating my review now several months later. I reinforced the rope with a paracord braid and the toy now lasts a very long time. My dog and I play with this toy everyday on our morning hike. He is a large German Shepherd with high ball drive. He carries this ball in his mouth several miles on our morning hike. We play fetch in the fields near our home and in the lake beyond the fields with this toy every day. This toy is his reward in obedience training and we play a lot of tug with it every day. Reinforcing the handle has made a huge difference as the toy lasts and lasts now with the improved rope. Great ball, we will always have a collection of them at our house!

Great for training and play!

My German shepherd love this toy! Great to take on walks with you as light weight and can fit in your pocket. Stands up to the toughest of play. Great as reward toy for training in place of treats! We always have one on hand at home or out and about!

Great for big dogs
Size: Medium, Number of Items: 1
Our pup is now 15 months old (nearly 110 lb and still growing). We got this ball when he was 3 or 4 months old. GOODS - - Our pup fetches with extreme drive, and the rope helps him quickly snatch the ball off the ground (versus a tennis ball, in which we are worried he will go head over heels at times) - Our pup also loves to play fetch in the water, and this ball floats great and again, the rope gives another point to bite onto - The yellow color is easy to see, even in grass - Our pup typically fetches the ball, and leaves the rope mostly out of his mouth. So, throwing the ball doesn't result in saliva-covered hands - It's pretty easy to throw the ball 50', and possible to throw it 100' - It doesn't roll/bounce, so if you are for example playing fetch on your front lawn and are concerned with a tennis ball rolling into the street, this one alleviates that issue - Our pup is spoiled and has several balls. This is absolutely his go to ball. We have woken up in the morning before to see him standing next to the bed with the ball in his mouth, asking us to get up and play. BADS - - Occasionally when he goes to fetch it, he will step on the rope as he tries to pull up on the ball. - We have gotten this ball stuck in trees multiple times. In fact, there is one stuck on the roof of our church from playing fetch on the lawn there. :-/ Not a fault of the ball, but if you start whipping it around like nunchucks, it might not go where you want. - The near max you can through this ball is 100'. And since it doesn't roll/bounce, throw distance is throttled. We often play fetch in a local baseball field, and have no issue wearing him out with this ball. However, if you are planning on throwing a ball the distance of half a football field, you might want to consider something else. SIZE - - We purchased both the medium and the large. Even though our pup is huge and can fit a soccer ball in his mouth, he still prefers the medium. It's easier for him to get in his mouth and breath while running back. The medium is the size of an orange, whereas the large is the size of a grapefruit. DURABILITY - - We have gone through about 4 of these balls, BUT this is because we lost 3 of them. We believe he dropped one out of the car window while we were driving, one is on the roof of our church, and I forget about the other one. On the first one we had, the stitching behind the black tape was down to a few threads after about 5 months. Given duration we use these balls (every day) and the joy he gets from them, I feel the durability is good for the price. - We do play tug with the ball at times, and no issues there Enjoy!
