Wow! Thats a really good idea!

I should fit one of those on my 2L Turbo Cordia Cage! This thing is a rocket!

using an electric door locker from a cage is the right track.hinge the top of the plate and use a small cable to pull the plate up and use a coil spring to help return the plate down.use removable pins on the cable for w.o.f purposes and a three way rocker switch.i beleive if earth is using the middle pin then two power wires for in and out on the switch would go on either out side pins on the three way rocker switch.simple really and only took me two mins to work out.....

next please....take two asprin and ring me later.........

I thought such an honourable and educational thread was worth bumping back to the top.

My idea-get a wof holder and have it mounted on the plate on a radio control type servo that turns the tag 90 degrees that covers a centre letter or is out of the way.

OR

have the plate hinged from the top and a big nut in the centre of the plate. Behind the plate have a electro magnet holding the plate down via the steel nut. Now when the plate hinges up, have a second electro magnet that catches the nut when its in the up postion. Have a switch that puts power to the normal position magnet or the hidden position magnet. If your on a mission, turn the hidden plate magnet on, wind will push the plate up and its locked and hidden. Once you go below warp speed, you turn the lower magnet on, lower speed and your carefully weighted plate at below 90 kmph drops back into place. PRESTO!

just hing the plate at the bottom and have a catch to release it you aint gonna want to put it up till your well hidden anyway

Gotta love resurrecting dead posts... Anyway, my thought on the matter, since I'm mid-way through wiring up a guys rally car, you could use one of the stepper motors that cars use to control the flaps inside the aircon system, it has two poles, apply voltage one way, it whirs along to one position, reverse them, and they go the opposite direction, the motor has a rod that it swings in a 90 degree arc, with plenty of geared torque to fight wind resitance.

i know of one person on a NC30 whos WOF normally sits horizontal just above the plate, but the constant V vibes have shaken it down to coever the centre two letters where the extra friction of the raised letters has stopped loosening anymore!

I think Ixion or someone here suggested going to a car wreckers and picking up the assembly from cars that have pop-up lights then customising the brackets to suit.

Yeah, was me. Little solenoidy shafty thing. Like on Honda Prelude headlamps. Goes back n forth, heaps of grunt to tilt a plate, just wire it up with a two way switch. Bit of piano hinge along the top of the plate, and connect the tilt solenoid to the bottom of the plate, angled back (bit of #8 wire would do the job OK, leave enough flex to accomdate the arc )

a unit for popup headlights would be huge for a bike and add so much weight.. go down to a radio control model shop, and look for a small servo. Mount it in the boot, then with wire/cable and some creativity, mount it to the plate so that it folds up. easy, fairly cheap, clean and light
