Is anyone able to tell me what the Black heat shrink smaller device is. I know the one in the clear is the "Light Controller" but unsure as to what the black one is. They both came in the same package in my FB Jets kit. Also if someone can tell me what voltage the Light Controller system runs on, that would be great.

What jet? Does it have an afterburner?

F-15. I have yet to unwrap the Turkey feathers. But that could be it. I will check.

Probably it. My FB F100 and FB T33 had the same controller for afterburner.

GULDUKAT Thanks. What voltage is the system? 7.4V?

Yes - I just used my RX battery. Never used a separate battery. 2S LIPO

thanks
