Eflite 90mm Viper TrueFire and BlueFire LED Afterburner

Regular price $39.99

Prior to ordering please read the note below on setting up the BNF plane with the Smart Throttle feature of the Avian ESC and Spektrum receivers. If you want have telemetry, reverse thrust and use the TrueFire or BlueFire afterburners you will need to purchase a new receiver with additional channels. 



TrueFire - Random flickering from 30% to 50% throttle to simulate the afterburner lighting/turning on. From 50% throttle to 100% throttle the afterburner gets brighter with full brightness at 100% throttle. 

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 - adjust the throttle position where the main Orange LED turns on. For BlueFire units the throttle position where the Blue LED starts to flicker can be adjusted. The ability to turn on and off the flickering affect is also provided. 

Setup details 

The BNF version has a Smart Throttle feature that allows for telemetry data to be sent from the ESC to the receiver (RX). This connection is not a traditional pulse width modulated (PWM) signal. It is a serial connection in order to provide the telemetry data to the receiver. Please read our notes here on the Smart Throttle configuration. 


Information on the system:

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.

Fantastic product... Fantastic delivery

This is about my eighth purchase from 5280RC. Their products are always on target and their delivery is always perfection.

Outstanding support !

The Eflight 90 Viper is somewhat unique in that the the throttle cable is serial versus the normal PWM .To get it to work, you need to do a few things differently. Since the AR631TA is only six channels, I went with the two RX method and added a AR620 as a second RX.

Frankly, dummie me struggled with the connections until I threw in the towel and contacted Larry. After couple of iterations, Larry was able to help me to get it to work properly and still have the reverse thrust and telemetry features of the esc. Can't say enough about Larry's support. He was determined in helping me get it right.

This is my fourth AB from 5280. I've tried a few of the other brands out there and though they all work fine, it's the high level of service and support from 5280 that keeps me coming back for more.

Freaking WICKED!!!!

\So, when this first hit the market I'm not gonna lie, I said "$85 Pfft is too much for a afterburner". But boy was I wrong! This little contraption is freaking neat. The way that it starts up blue with about 30% throttle, flickers and starts the amber. I'm super impressed. I want one for every jet I've got. Really easy install. Mind you do have to swap the throttle and aileron channels, but its worth it. 5 stars all the way. Now I need to paint the inside of my fuselage so there's no bleed through of light. Ladies and Gentlemen, get yourself one of these. You wont regret it!
