This Afterburner LED Light system (E631) is for Freewing single exhaust INRUNNER 80mm EDF jets and SOME Freewing 90mm EDF jets only. It also fits the new 90mm 6S Eurofighter with the 3668-1960Kv motor. If you would like to use an Afterburner LED Light system for non-Freewing EDF jets or other 90mm Freewing EDF jets, use the Freewing Universal Afterburner Tail Flame LED set for 80/90mm EDF Jets (E632) by clicking here.
Note: Please ensure that your Freewing model has an INRUNNER motor and that it has the 2 mounting screw holes on the back of the motor. All 80mm jets sold in the last 3 years use the 3658-1920kV inrunner motor and this Afterburner kit IS compatible with SOME of the 3658-1920Kv inrunners for 80mm EDF jets (see picture and note2 below). Some 3658-1920Kv motors do not have the required screw holes on the back of the motor so it is best to check before ordering. If you do not have the required motor screw holes, use the E632 Afterburner kit.
Note2: This E631 Afterburner is compatible with SOME 90mm Freewing inrunner motors including the popular 3672-1900Kv motor in most 90mm Freewing jets. Freewing updated the 3672-1900Kv motor to add screw holes for the Afterburner kit and has been gradually phasing in the new version of the motor during 2022 and 2023. Please check the back of your motor for 2 threaded screw holes. If the screw holes are not there, we recommend the Freewing Universal Afterburner kit SKU: E632 for most 90mm jets.
Note3: Does not work with the Spektrum Smart Avian ESC.
