From 50% throttle to 100% throttle the afterburner gets brighter with full brightness at 100% throttle. Select-A-Fire adds the ability to adjust the throttle position where the main Orange LED turns on. The ability to turn on and off the flickering effect is also provided.

Select-A-Fire BlueFire - Random blue led ring flickering from 30% throttle to 50% throttle. Center afterburner led is not on during this portion. From 50% throttle to 100% throttle the center afterburner led gets brighter with full brightness at 100% throttle. The blue led ring is on at a lower intensity during this portion. Select-A-Fire adds the ability to adjust the throttle position where the Blue LED starts to flicker. The ability to turn on and off the flickering effect is also provided. 

LED afterburner with flickering effect on startup and increased brightness during the throttle sweep. Afterburner comes on at 30% throttle. No additional radio (TX) programming is required to achieve the realistic afterburner effect. This is a plug and play system. 

Includes a 3D printed motor mount, 20" extension wiring from controller to LED, connection to a 6S battery balance port and receiver. We can offer a 4S version if desired. Just let us know. 

An integrated Y cable is provided with the controller to split the throttle signal from the receiver (RX) and provide it to the afterburner controller and the ESC. 

The controller itself weighs 18g.

The dimension listed is for the outside diameter of the motor. The unit can be attached to the motor using a zip tie, Gorilla tape or FoamTac glue. See photos for more information. 

Installation instructions:

1) Remove the motor per the manual instructions. 

2) Attach the afterburner LED unit to the rear of the motor using FoamTac Glue. Tighten zip tie and add Gorilla tape if desired. Leave the FoamTac to set for 24 hours and then you can remove the zip tie if desired.  

3) Route the LED wire to the battery compartment.

4) Connect the LED wire to the TrueFire LED controller.

5) Connect the ESC lead to the Y splitter. One end goes to the receiver throttle port and one to the TrueFire LED controller Throttle connection. 

6) Connect the TrueFire LED controller Battery connector to the balance lead of the battery. 

7) Power on the plane and the transmitter. Make sure your plane is secure prior to adding throttle input. Give it throttle and enjoy the TrueFire! It gets really good around 30% throttle input.

Fun, interactive toy!
So much fun! Bought this for my lab. She wasn't sure what to think of it at first but seems to love it now! I like that it's rechargeable too.

Overall, I highly recommend it!”
Great toy! My dog loves it 🐶 The ball moves on its own and keeps him entertained for a long time. It’s perfect when I’m busy or not at home. Good quality and fun, but maybe not the best for very aggressive chewers.

Puppy loves it but the battery is awful
Color: Blue
Our puppy loves playing with this ball, it does what it says and keeps her occupied for the entire 10-15 minutes the battery lasts. I have to charge it several times a day, though the light never flashes red when the battery is low, it just doesn't work anymore. It also makes a beeping sound when she's playing with it that is super annoying, which sucks because the ball itself isn't super noisy even in the hardwood floors. I wouldn't purchase this again, and we'll probably have to toss it out within a week or two, I really don't see this thing lasting very long. Without the movement, it isn't a ball we would let her play with because she is a strong chewer and the material doesn't seem chew proof at all. I'm only giving it 2 stars because she really does love playing with it, but the battery life and beeping sound are atrocious.
