yeah, that would work on radios with a proper on off switch wired rather than hard soldered to the pcb. you have to have some way of isolating the diodes from the battery when the radio is off.
LiFe won't last longer than decent LSD AAs, unless you have more mah of liFe than you do of AA, and to do that would require the rather bulky and damn heavy A123 26650 cells - a 3s pack of those (2300mah) would weigh more than half a lb.

And the life packs will last long they have ones like lipos 3s that are only 150Grams and and 2100MAH.

awesome, glad I could help. I just picked up another ex-1 ur, fixing to get the same mod too. Did you have to wire in the 12k resistor on yours as well? I hadn't read where anyone had to do that, wondering if it was just something screwy with my radio. I may leave the ur to where I can more easily swap out modules.

i just solderd the resister in i did not even try it without it so i don't know...I doubt your radio was messed up you probably need it for some reason because if your radio was broke the FM unit would not work correctly also.

I bought a Losi RTR radio thinking that I could use the spektrum board out of it. It looks like it will work since there are only three contacts coming off the board, but the thing is tiny and my soldering Iron and fingers are huge. Has anyone else tried this and what do you think?
The RF board is also attached rather firmly to the main board.

Well, I missed out on a sweet deal on a KO EX1 mars radio. Oh well! 
Then I read on another post that any module base radio can be converted to the Flysky module. Now that changes everything!
I have my JR R-1. It's a module base radio. So I think I've found the correct pins on the radio that I need to hook the FS to.
From left to right looking into the module bay, pin #1 is reading around .75 volts, pin #3 is (+) positive, and pin #4 (-) is negative. Voltage reading on the + and - is the pack voltage of 10 plus volts.
So now I'm waiting on a module. A buddy of mine has one of the GT3 radios he's not using, so he's going to sell it to me. But it'll be next weekend before I can get it.
So far things are looking good.

Well, I am now the proud owner of a JR R-1 with a Flysky GT3 2.4 module. Only thing I had to do was trim the molded raised plastic around the pins in the back of the R-1, and trim about an 8th of an inch off the pins. Plugged & snapped right in. I put the receiver that came in the GT3 in my micro ( i figured it had already been bound), and turned everything on. Works perfectly!
Next race I go to (in two weeks) I'll test it out around other radios to see how it fairs. But I'm not expecting any problems. We'll see.

Another +1 for a great mod.
I had a eurgle module from the gt3, but it's the same stuff. Everything worked great first try, thanks for doing the legwork and making it easy junkman!
For those looking to do this, I used a nibbler tool to trim the board to fit in the KO module slot as well as make room for the connector on the side, easier/cleaner than a dremel.

will this mod work on a KO Propo Eurus Radio?

how can you figure that out? the + - and PPM signals. do you need a voltmeter?
