Thanks to Ed for developing this IBEC. I have been flying one of them for several months now and I have nothing but praise about the unit. I am running a 2300 MAH A123 battery. 7.2 volts off the charger in to my Futaba Fasst receiver and regulated voltage to my ignition. Great product!

I totally agree, I have 4 of them and they are perfect!

Here's the business end of my Great Planes RV-4 with the DLE 20 in place of the Saito 125. I'm expecting to be a few ounces heavier but the plane flew so well with the 125 at about 10 lbs that I can't imagine the extra weight will matter.... and an uptic in power would be welcome. I'd love to be able to do aerobatics with just a bit more authority. Don't want to hover or any foolishness like that (for an RV-4), just fly it scale and have a bit of power to pull out if I get into any trouble at all. This is the just the latest in my move to electric and gas... I hope to see the last of my glow go away in the next year! First prop will be the APC 17x6. Depending on the result I may go dig out a wide blade 17x6 APC I modified from an 18x6W a year or two back for another airplane. If/when we get a warm spell and I get a chance to break it in a bit, I'll take it up for a spin and do some taching and such. The ignition unit is tied to the bottom of the motor box and I'm awaiting a new cowl so I can get rid of the extra holes but it should fly the way it is for now.

Looks good!

Anymore photos of the engine installation?
Folks are often inquiring about choke/throttle linkage setups.

its the 120 size, i kinda figured the 20 would be small for my type of flying. but i had to ask.

I am going to build the GP Extra 300s and install the DLE20 in it. I want to use A123 Battery and have seen several say they are using it with two Diodes. Can you tell me what value diode you are placing in line to reduce the voltage to a safe level. Thanks for any advice.

You did right. If you just wanted to fly scale like, this DLE20cc would be adequete. But for 3-D, it's just not enough on that particular plane.

One thing that might save you a bit of grief on the 1.20 size; beef up the area where the stock L-G mounts.
Wood in that area is barely enough, and one rough landing, you'll be a b****in. Thought I'd let ya know that, hope it helps.

Thanx for the lg tip, never really thought about it.

Yea, what he said. I bought 10 for 90 cents at my local electronics store and then bought a 6" extension, cut about an inch out of the red wire, soldered them in series and then put heat shrink tubing over it. Then all you have to do is connect it between the ignition and battery. It dropped the voltage to about 4.9v under a 500ma load on a 3/4 full A123 battery.

Thanks for the link! Just made an order.

Thanks Jodi and SpinnerRow this information on the Diodes and their installation will help greatly when I get to that point of the build.

You must realize that by doing this, you have no filtering at all on the power leads from the receiver to the CDI, right? The Opto you have may as well not even be there, because you are piping the CDInoise directly past it on the power leads. Luckily, you can often timesget away with this on a 2.4 gHz radio, but you should also be aware that you now have a greaty diminished safety margin in the event that something else goes wrong. For example, suppose the plug cap comes loose, but does not completely detach. The noise now coming back along the wiring has just gone way up.

Also, please be aware that it does not necessarily require 2.4 gHz energy to interefere with a 2.4 gHz receiver. Every spread spectrum receiver has a frequency synthesiser curcuit in it that is fed by a fixed frequency crystal controlled oscillator, most likely one running at 10 mHz. So, if you bring enough RFnoise into close enough proximity to the synthesiser circuitry, bad things may happen. And the fact that you have now effectvely turned your receiver power bus into a broadcast antenna for CDI noise isn't such a good idea. You may get away with this, but you should at least consider going to a separate ignition battery if you don't want to usea device that would filter the power leads. Good luck!

On one of my setups, I'm using an MPi MK3 regulator with one 2600 2-cell Li-Ion battery feeding in it, and from that one line goes to rcv, the other goes to Opt Ign Kill unit. Better, or still not so good? Rcv & ign are seperated by the regulator, but have a common battery/source.

I've been "getting away with it" for at least 2 years on 72 MHz PCM and 2.4 systems. In my experience and opinion IBEC devices are completely unnecessary. Power for my ignitions on all 50cc and smaller planes comes directly from my Rx, on 100cc planes it comes from the power expander.

It sounds like there is still an unfiltered path.

My Feedback: (7)

Wouldn't the same should apply to your product line as well?

I'm using a Opto Ign Kill by 42% Products, with DSP
Noise / Loss of signal Filtering, and OPTO Coupled input/output.
That should be doing the job of isolation.

Sorry if an open discussion of this topicoffends anyone. Facts are pesky things though. If anyone has further questions, please feel free to send a PM.

Good night all!

What is the current draw from the IBEC also can my 2 Li-Ions(2600mah duralites) feed all my servos  and ignition.

Happy Landings

Especially if you want to prove them.
