Default Power Expanders

Looking for any history on these good or bad. A friend uses one with great success. But we are a small club and wanted to get more input.

Thanks in advance, David

In general or that one?

Most of the time, unless you have a fairly large and complicated setup, you're fixing a problem that doesn't really exist.

I found this one on Mile High RC. My reasons for thinking I need one: It would eliminate the need for 2 Y harness on the ailes. Would give me battery redundancy on the RX and ignition. Would give me a built in kill switch. Would allow me to run a different voltage to the servos and RX.

That's my thought process anyway. It's less than $100 to do all the above, David

Dave it really depends on the use and what radio you're flying.

Most planes, it solves a problem you don't have an adds expense and unnecessary complexity.

For example I have complex warbirds with a Spektrum Power Safe rx and 2 batteries. 9 servos, electric gear and the ignition.

A more complex large A-10 uses one of the Power Box systems with integrated gyro, redundant batteries and fail safe switches.

For an average 60cc aerobat you're wasting money

Thanks Andy. I'm still contemplating. I use a 10C Futaba and a 8ch RX. It's not the latest and greatest up to date radio. But it's hard to justify an upgrade on it. It has given me zero problems and I can program it in my sleep. As much as I appreciate you point of view I am however leaning toward one of these. I like the idea of redundancy on RX and ignition with only 2 batteries. The 50cc Extra I am replaceing was lost due to a switch failure on the ignition at a low ALT. This unit would have saved that plane.
Thanks, David

I use one of those, the black one, in my 100 cc slick 540. I bought it from Mile Hight RC. It works great, I run dual 3 cell 2200 lipos on it. You will love it! Just my 2 cents worth.

Thanks for the reply Vetagator. I did buy the red one from Mile High RC. Bought 2 LiFe packs to go with it from Redwing RC to go with it. Shop time is limited or it would be in already :-)
