PN 36IN

This Afterburner is for the inrunner motor version (motor PN 3658-1920kV) - latest version.

Options

Select-A-Fire 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. 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.

Good pillows; wear a mask when fluffing and airing out
Color: Memory Pillow, Size: Standard
Searched everywhere for comfortable pillows, finally found this set. Perfect density and firmness, very comfortable. Downside is that they were covered in some type of white powder which dispersed as I was fluffing them up. Fiberglass, maybe? I recommend customers fluff and air them outside before use, and wear a mask. Pillows had an industrial smell, which dissipated after 20 minutes in the fresh air.

They are using different/cheaper shredded foam then they were 1 year ago
Color: Memory Pillow, Size: Standard, Color: Memory Pillow, Size: Standard
The shredded foam used last year was really nice and soft and even firm to a point where your head is supported perfectly while you sleep. now the 2 extra pillows I received this weekend have completely different shredded foam which seems to be cheaper. Also when you unzip the pillow cover and get to the part where you can unzip the other cover where the foam is no longer is there. so they are using cheaper shredded foam and a cheaper cover to where the foam is and you can no longer unzip the second cover to see the foam. but I can easily tell that they are using different and cheaper foam which isn't true memory foam. their new blend is too fluffy and the pillows are floppy and too soft. the old ones i bought 1 year ago are heavy pillows that are true memory foam which your head molds into perfectly and are amazing. these new ones they are making aren't worth it. In one picture you can see the cover with different colored cheap foam and the other picture with the green and white thick premium quality shredded memory foam. The other pictures show how the old ones are thick and firm and moldable for you head and the other 2 are floppy because they use cheaper shredded foam. They need to use the shredded foam they used last year! it was really good! Now they are not true memory foam pillows anymore due to changing from premium shredded foam to cheap shredded foam.
