LED FLASH??
 
Has anyone used an LED for the main gun flash on a Tamiya?If so, you have a link to how to wire this up?

Just make sure you dont try too use the MFU flash curcuit. It is a very high voltage . I know guys do it but I dont know what they are using for power. The stock micro switch can still be used to trigger it.

I assume you mean the micro switch on the recoil unit. That would make sense. I suppose you would need a higher voltage LED as well? Most of the ones I have run off of very low voltage. Maybe 1.5-2v.

Hi Joe the tamiya unit will fry a led ...maybe do it like panther said with the recoil unit make a jumper and power a led off it see what voltage it is ... you can get higher voltage leds or you can use a diod in reverse to lower the voltage or a resistor.

You can directly wire a 5mm LED in parallel with the gun recoil . There's no need to add a series resistor as the voltage is just right. The only drawback is the flash is longer than usual.

Thanks Gerry. Ah, so it would not be that same split second as the high intensity unit does?

Yes.

Yup, what they said. i know there is a way to do it but forgot the diode part.
