Hi all. I saw that there was a recent thread related to HV IBEC capabilities. This is just to confirm that Tech-Aero Designs LLC is now offering the Ultra IBEC HV for use with higher voltage ignition modules, with a choice of 5.9V, 6.3V, 7.3V and 8V output to the ignition via jumper selection.

Please note that nearly all present day ignition modules will work reliably at the 5.9V setting, however we are continuing to offer the original Ultra IBEC with its jumper selectable range of 5V, 5.3V, 6.1V and 6.6V to assure that everyone is able to configure their ignition system the way they prefer.

Please also note that the HV version is the same design as you've been using for years, it just has a change in the value of one resistor component that causes the output voltage range to shift to the new higher range, and there is no price increase.

Thank you!

What voltage setting do you use for a single DLE ignition?

Why are there so many different voltage settings?

And....do you use the standard or high voltage version for the DLE?

Awesome ��

This isn't a DLE issue but applies to pretty much any engine that uses the RCexl ignition. These ignitions have been produced for different voltages and I have (4) different ignitions here that came with different DLE engines over the last 10 years. Their working voltage printed on the ignition box includes the following ranges: 4.8 - 6 volts, 4.8 - 8.4 volts, 6 - 12 volts and 4.8 - 14 volts. These are pretty much in the order they were produced.

I'd set the voltage from the Tech Aero with in the range of voltages printed on the particular ignition I was working with. Any ignition labeled with a high voltage of 8.4 volts or more will tolerate full Lipo voltage so you could use the highest setting on the Tech Aero. There are multiple voltages available from the Tech Aero so you have a choice of voltages to work with the particular ignition you have. Stay within the range of voltages on the ignition box and you should be good to go. One exception, the older 4.8 - 6 volt ignition always seemed to work best with at least 6 volts and would sometimes kick back or misfire at 4.8 volts.

Use either the HV or regular Tech Aero IBEC depending on which input and output voltage range best suits your needs.

Appreciate the info. I will have to take the cowl off to verify but believe it is the 4.8 to 8.4 version. If that is the case, what voltage should it get set to? It sounds like I would need the HV edition IBEC then.

Also....can you use different ignitions on the same engine without changing anything else?

Lastly.....why would you need to operate it at 12 or 14 volts? That seems really high!

If you have the 4.8 to 8.4 V version, you could set the IBEC to any voltage in that range ..... but many would probably opt for a voltage between the middle and the higher end of that range as some ignitions are known to misfire or kick back at the lower voltages. That may or may not be the case here and only experimenting could yield an answer. I really wouldn't worry about it much unless you experience a problem. With that ignition, either of the Tech Aero models would work just fine.

There is a trend towards higher voltages and perhaps the higher voltage ranges on the ignitions reflects that trend ..... I don't know. The next wave of servos coming on the market also reflect higher voltage operation so maybe Rcexl just wanted to get a jump on the market with higher voltage compatibility for their ignitions. I don't worry about the high end of the voltage range but do worry about the low end. I stiff prefer LiFe batteries and their voltage is on the low end of many of the newer ignitions which could be a problem for me and many others who have the same preference.

of many DLE and DA engines, I have never changed the IBEC voltage from the default setting.

I run my DLE 55RA at the 6.6 volt setting. Works fine.

Truckracer, FGNewbie and Judge - thanks guys for the info.

How do you program these? I have travel set to -150 on one end and 150 on the other. Tried 0 at one end. get light no mater what setting i use.

Instructions supplied or via website are pretty strait forward -
Are you on a switch or slider or dial ?

You may want to plug it into a servo tester if you have one, just to see the light turns on and off properly. I typically use -100/+100% but it typically turns on and off with less than 100%.

Look carefully at the photos in the instruction manual to make 100% certain that the end plugged in to the receiver is the receiver input lead, and not the battery input lead. It's possible the leads were mislabeled, although I've not personally seen that.

You can put it on a slider, a knob, or a switch. Travel at 100% in both directions. There’s nothing to program. On the unit but possibly in your transmitter. If using spektrum the monitor will tell you whether a signal is being sent.

Yeah they're all straight forward and can use any open channel. No programming whatsoever on the device itself.

Depending on your system/transmitter, and/or mixes, make sure you're plugging into an open channel and not one that's mixed with something else. If there's any programming involved it will be in your transmitter. The device should work with travels set at +/- 100.
