Have about 25 flights on my dle20 with one 2300ma nimh powering remote kill,ignition and tack out of 2.4 futaba no problems,bout 60 flights on other 120 planes same setup.

I have hundreds of flights with 1 battery, 1 switch, Opto-Kill plugged into the Rx multiple planes andRxs,both 72 MhzPCM and 2.4 Ghz systems,not so much as a glitch.

What type of battery are you using?

2600 mah LiFePO4, (A123)

Some people are just lucky,I can build a ignition system that will eat up any 2.4 or PCM system.I have done it just for testing.
BCCHI

Exactly, and which was why I asked the questions I did in such a pattern.

NOT the best salesmanship IMO.

"eat up"????

Hey Jody, do you regulate the voltage? with what? TKS!

No, I splice one 1N4007 diode into the + lead of the Opto-Kill output.

Actually, I put one in the positive and one into the negative on mine. It helps with any kickback voltage from the ignition. For those that don't remember, this is a drawing I posted a while back but I made some changes to the way I hooked it up. This is exactly how I have mine.

Here's a few more shots of the engine installed in my RV-4. I used a simple ball and linkage going forward for choke. I'm not thrilled with it but think it will work. Fuel tubing in the way to see some of this clearly but hopefully you can piece it together from the multiple views.

Spinner and or Jody,

Could one or both give a detailed discription of your single battery, single switch set up.

Thanks

I thought I just did that three posts up. I hooked the 42% up as per their instructions and stuck my diode harness between the ignition and 42% opto kill.

Battery into switch
Switch into Rx
Opto-Kill switch leg into LG channel (5)
Opto-Kill input into any Rx spare channel port
Opto-kill output to ignition with one 1N4007 diode spliced into the + lead

Thesingle switch turns on both the Rx and ignition at the same time. This method provides 1 manual and 3 remote means of shutting down the engine.

1) Turn off power switch on plane, shuts off everything.
2) Turn off ignition power with programmed switch on Tx.
3) Programmed throttle kill shuts off engine...NEVER leave home without it.
4) Turn off Tx, Opto-Kill turns off ignition with loss of signal and throttle kill activated as a programmed failsafe.

You could add a 5th if you install a choke servo, if you use 4 cellNicador Nimhbatteries for the Rx you don't need any diodes but I don't recommend 4 cell power suppliesfor anything but ignitionsor small glow powered planes.

I use the 42% Products Opto-Kill.

Per the 42% instructions, the sequence is battery, switch, Opto kill. From the Opto kill it goes to ignition and RX. Now, how are you powering the RX with that same battery and single switch? Does the battery have two power leads? Does the switch have 2 input / output leads? Or are you simple using the 42% Opto as you power source to the RX? Not trying to be a smart @$$, just trying to piece the puzzle together. And yes your drawing was good, but it didnt solve the mystery for me.

Thanks

Jody,

Opto kill power input from RX, was what I was missing in the sequence. For some reason I thought the Opto kill had to be powered by the battery directly through the on/off switch.

Thanks

You asked for a detailed description of a single battery, single switch system, my post is very simple to understand, it is exactly the way the instructions state, batt, switch, power buss. You may first need to understand the products themselves by using them the way their instructions state.</p>

Jody,

Isent you a PM requesting this very same information, thanks a million.

Mine has two leads or I guess you could use a servo Y harness to split it.

If you use the second lead from a battery or Y-harness the onlybattery lead to power the ignitionyou will need to add a second switch for the ignition.

Jody and Spinner,

Thanks for the info guys. I got it figured out now.

Jody,

Would it not be OK to install the y-harness AFTERthe switch? Iwas thinking about this becaused Iam using a 7 channel receiver (1xThrottle, 2xAilerons, 2xElevators, 1xRudder) and only have the GEAR channel as spare.

Thanks

Dale

For others lurking, they're using A123 batteries.

Setups for LiPo or Li-Ion would be slightly different.

Not true, if using a dedicated power lead for the ignition off of the same receiver A123 battery and an optical ignition kill switch like so many of my customers......you don't need a second switch (but have the option to use that second switch if you wish) By switching your ignition on and off thorough the opto isolated kill switch the ignition power is shut off when switched or radio shut down. No extra power draw during the time the plane is sitting waiting to go out again...I have let them sit with no battery draw.

I am using an A123-1100 for some 70+ flights on my Slide-58 profile with this exact setup. I am using an A123-2300 on my 50cc Suhkoi profile with this exact setup... Also run ignition off of one of my A123-2300 same way in the 40% plane.

Thats all right Jodi, but if failsafe is not set to Ign. off on 2.4 receivers with signal loss Transmitter to receiver ign power stays on.
I needed to mention that here.
I supplie from A123 direct to syssa kill, signal only from receiver (single wire) works, no issues
