LEDs for Night Flying

I can fly my night flyer Slow Stick and UFO to several hundred feet at night and easily see it. The super bright blue LEDs are so bright they light up the ground from very high. The UFO creates a circle of light on the ground.

The super bright LEDs were bought from http://abctronics.com/
LEDs are on this page: http://abctronics.com/abcTronicsPrice_E_LEDs_3mm_and_5mm.htm

I have used these LEDs:

Red 3mm: 2700 millicandles, 20 ma average current, 30 ma max current, forward voltage = 1.95 volts

Blue 5mm: 4500 millicandles, 20 ma average current, 30 ma max current, forward voltage = 3.15 volts

White 5mm: 9000 millicandles, 20 ma average current, 30 ma max current, forward voltage = 3.15 volts

Green 5mm: 10000 millicandles, 20 ma average current, 30 ma max current, forward voltage = 3.10 volts

Take the forward voltage for each LED, the average operating current of 20 ma, and plug them in with your source voltage to the LED calculator here:

That will give you the resistor you need to solder in series with each LED.

I was inspired by this thread at RCGroups for my UFO flying disk:

except I am going to sequence them with a 12c508 pic and a few transistors. I have four sets of LEDs on the UFO; three sets in alternating colors around the circumference, and another set on the three vertical tails. The type of the flashing will be controlled by the gear channel on the radio. One of the PIC inputs will read the PWM signal and set one of several different flashing sequences and flash rates. The pic code will be added here when it has been tested. I have not flashed this to a 12c508 yet, but it is almost the same code I use for my aerial photo digital camera controller,
