landing flight light

could anybody help me plz in flash circuit board.
i want the flash on when the glider start to fly and off when its landing on the ground

Are you talking about a disposable camera flash? If so, you won't be able to get it to stay on permanantly - it is only rated for a very low duty cycle (breif pulses). You'd be best off using a super bright LED.

thanks andrew for ur reply
the aircraft will fly 8 meters so i need that circuit to flash on when it starts to fly and when its landing on ground it switched off

Flash, or stay constantly on? In either case, using LEDs is probably the best bet.

saam

yea flash
can you show me the circuit

You'd want a 555 timer set up in astable mode, using a transistor to control the LEDs.
