I have just purchased a gas airplane with the DLE 30 all set up to fly RTF... The opto kill switch is not marked with a brand name... I can not get the red light to come on that indicates power to the EI.... This is a brand new and never flown or run setup... My main question is: As I am using the #6 slot on my receiver for the opto connection What should I do next with the transmitter to activate the Opto/EI... get the red light to glow? Futaba 9C transmitter... This airplane has two batteries... one for Ignition and one for the airplane... two switches....

This is from memory but if I recall, go to Paramaters menu and AUX CHANNEL and set the channel its hooked up to to the switch you want.

Then make sure the kill switch has power.

You can also use the monitor screen and flip switches till you see what is moving the bar for the channel the opto kill is plugged into.

If it is the non branded hobbyking switch it needs a 6 volt ignition battery for the switch to work, which is less than ideal for some ignitions.

It does look just like the one in the picture.... and I am using a 4.8 volt 2400 battery..........

also you can use any old spare servo to check the channel etc. should just flip from one extreme to another.

i´m really happy with my rcexl opto isolator switches... they are on ebay i think and really cheap.. plus as dle ignition is rcexl, well it just lets you know you are using a pre-tested setup.

Thanks to all that answered and the suggestions... I will check out the options and get this bird in the sky....

Very good advice..... I did use a servo in the #5 and #6 Slot on my receiver and found quickly the switch to activate my opto kill switch... Every thing seems to be working and the red light turns on and off from switch 8 on my Futaba 9C.... next will check the spark itself and should be ready to fly...

Thanks ceecrb1 for your suggestion... Richard
