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. 

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 value for solar watch
Color: Black/Orange
Nice watch! It is plastic like but it is solar. No indiglo button only a little luminous on the hands so you don't want to wear it in tje dark and expect to check the time. 45mm case is good size for my wrist and the band works good also, Not too long not too short. Overall a good watch with no problems

Do not buy
Color: Green/Black
Do not buy. When I received the watch it did not work and the battery was dead. I bought a new battery and it killed that one as well after about a month.

Inexpensive doesn’t mean cheap.
Color: Black/Orange
After 10 months, zero complaints. Well, I got rid of the horrible NATO strap 🙄. That’s a personal preference. Easy to swap out to whatever you like. Keeps accurate time meaning it’s the same time. I’m not micro analyzing it and the seconds gained/lost. It has a confident look and feel and makes you feel good when wearing it. Sure it’s not high priced but it’s not cheap. Very comfortable, light and not unincumbered. If this is what you’re looking at, you’d be satisfied. Great looking, durable and simple watch. Full confidence.

Budget Seiko Prospex this is not
Color: Black/Orange
Bought this as a cheap work watch, but I guess all the budget went into the solar technology. No date adjust feature, gotta crank the crown over and over to adjust the date. (Also no screw-down crown, but that's expected at this price) Fake diver bezel. Lol why? Cringe as heck. Should of just put a compass bezel on there instead tbh. Cheap plastic crystal, scratches and mars just by looking at it. Okay NATO strap. Falls apart quickly, but it's easily replaceable with a better quality one. Decent lume on the hands, but none on the hour markers even though it looks like there is. Looks cool.
