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.

Great shirts have to iron first
Size: XX-Large Tall, Color: Black
They feel great the material, they’re thin, the style looks good, the length to and below my waist is good. For the cost they’re good shirts and they’re definitely loose fitting, however they shove them in a tight bag so if you plan on wearing this straight away from delivery day make sure you have an iron ready every single collar and I ordered over 7 shirts comes folded over. Took a star away for the fact they don’t pack them how you would find a higher price shirt packed and typically wear ready.

Simple and nice.
Size: 4X-Large, Color: Dark Grey
Nice shirt. Light weight. It’s true to size and skin friendly because it is cotton.

Perfect!
Size: Large, Color: Beige
Cool, comfortable, with a little stretch. Comes out of the dryer wrinkle free (be sure to hang it up right after you take it out of the dryer) price was reasonable. I measured my husband's neck and it fit exactly as it should. Good length to the back of it too, which is sometimes a problem for my husband. Do not see any quality issues. Not excessively thin or too thick. Really, I can't think of any way to improve on this shirt.

Nice shirt, but sizing isn’t ideal for big and tall builds
Size: XX-Large Tall, Color: Black
The shirt itself is decent quality and looks good, but the fit wasn’t great for me. If you’re a big and tall guy, this may not be the best option. The material has some stretch and feels comfortable, but the overall cut runs smaller and doesn’t offer much room in the shoulders or torso. It works better for slimmer or more standard builds. If the sizing works for you, it’s a nice-looking shirt. Just be aware that it’s not very forgiving in the fit if you need extra room.
