Frequently Asked Questions

Will this fit my RC jet?

Our Universal Burners are designed to fit Inrunner Motors. Will fit most Inrunner motor on the market. E-flite, FMS, Freewing, etc. Some trim of foam might be needed for single motor jet with dual exhausts. Like the FMS Rafale. See a list of campatiable Jets here.

How do I install the burner?

You can check out our instruction page here. Videos included.

Why my burners won't light up?

Each burner unit needs to be calibrated just like and ESC. Please follow the Calibration instruction here.

Plug in the receiver/jet prior to plug in the balance lead of the burner. Double-check if the throttle trim is zeroed.

Will my burner work with Smart ESC and Thrust reverse?

The answer is yes & no.

Yes, you can use our Universal Afterburner with a Smart ESC (Avian Smart ESC e.g.).
However, when connecting the unit and a Smart ESC together on the same channel via a Y-harness, you'll have to calibrate the unit on a separate channel first. This is because signals from a Smart ESC will not allow for proper calibration of the burner unit. When you finish calibrating it, you can connect both of them into a Y-harness for normal operation. Additionally, ensure that you connect the ESC to the battery first, then the balance lead afterward, otherwise calibration may be required because of the serial data coming from the smart ESC.

Unfortunately, when plugged into a Y-harness, current version of Universal AfterBurner does not support thrust reverse.

A simple solution is to connect the unit to a separate unused channel and mix the throttle channel to the channel being used for it. This would solve all the problems above.
