Simple delta

Today my brand new simple delta had her maiden in the moonlight with her lights on. It was kinda hard to trim her because she wanted to dive and it felt more complicated to trim in the dark. After I got her trimmed out she flew beautiful, loops, inverted loops and fast rolls. When the battery started to feel weaker I took her inn for a high alpha or what its called landing. I stopped the motor when she was about 20 cm above ground and let the nose fall into the snow. I got some snow in to the receiver or esc in the front, so I couldn't fly more than that battery. She is now standing in the hall, drying up

My setup
Motor: Turnigy C2230 1780KV
ESC: 10A brushless
Servos: HXT500
prop: EP70x35

I've got 20 leds on my SD for night flying. I can switch them on and off with the TX gear channel. They are driven from the RX by a modified servo circuit.

Pulled the motor and mount off today. Gave full throttle with 3s and 7x6 apc prop. The motor just flew off! The glue is curing right now. I guess -12C is to cold for my foamies.

How did you modify the servo circuit to turn the LED on and off?
Do you have link to doing it or did you figure it out yourself?

I have a link that explains how to do it http://www.helifreak.com/showthread.php?t=271481

One thing that I've done on some of mine that differs from that guide is that I've used the potentiometer that is in the servo in stead of using resistors.

Quick and simple way to do it:
1. take the servo apart
2. replace the motor with a LED
3. connect the circuit to the rx
4. turn the tx and rx on
5. set the switch you want to light the LED to on
6. is it on?
----a. yes, try switching it off. Should be working now
----b. no, try all positions on the potentiometer
----c. tried all potentiometer position and still not working. Shut everything down, turn the led around and goto step 3.

Hope it all makes sense
