DX3R with lipo
 

Hi, i have modified my DX3R to receive a lipo ( 1S3000) and that work perfectly, i have put voltage alert to 3.3V, and after 1 week of use, it's still at 3.8 V.

I don't have any issue or other problem.

Got Pics of it?

FYI you can use 2s lipo packs in the 3r. Ive got over ten hours on my radio after swapping it out with no adverse signs from the extra voltage.

How does one do this?

I just took the radio apart, pulled the stock batt tray, cut the wires goint to the tray for tower and soldered in a female servo lead. I use a lipo rx pack and 1/8th buggy tire foams to take up the extra space.

/\/\ keep us posted. ten hours huh? Well your that guy who finally did it. You'll always have that, even if she explodes in your face! The world thanks you

Ohh this is slightly misleading or its my fault, because i was thinking you put a regulator on it but infact your running 7.4v with a LVC correct?

I have do the same thing but with a 1S3000 lipo ( 3.7 V ), it's a Tony clark lipo for Gaz ignition motor.

Pics soon .

I did the Lipo convert yesterday on my 3R. I used a 2S Lipo, 7.4v 1500mah, and I have the cutoff set at 4v. I'll see how much time I can get on a full charge. I did notice the radio is a little lighter now too.

I also took the idea of using 1/8 scale buggy foams as spacers.

Interesting mods guys. Just as a heads up this will void your warranty.

This is true. I didn't cut any wires however, I just unsoldered the wires form the battery tray, so in the event I wanted to use 4 AA's I can put it in really quick.

I think my Warranty is over, but I don't know for sure. I know it is on my DX6i !

Cmon Gary. You know you want one! But seriously spektrum knew we were going to want lipos for them. What was their thinking behind choosing to stay non lipo? I will probably lipo mine very soon. Haven't heard anything bad yet

Honestly I don't. My radio works perfectly with NiMH rechargeables. I don't know what their reasoning behind going LiPo was but I know what mine would be. Even with a regulator you could have heat issues. I wouldn't want that inside of my radio honestly. Plus a single-cell LiPo has too low of a voltage output, meaning you would HAVE to use a 2S, and you're right back at the regulator again. Plus the goal was to make this a radio that ran off of 4AA's.

I know my reasoning was to stop having to carry AA's around. I have 8 or so rechargable ones, but they just seem to take for ever to charge, and now my 3R is lighter than it was before, and I don't see how there could be a heat issue, with my Lipo I was using it as a battery to power my SR3100 and JRDS8711 Servo direct, with NO regulator, never got hot. Of course my 2S lipo is the size of a Servo, so it's pretty small.

If you're not regulating the voltage into the receiver and not using a High Voltage servo you're going to shorten the overall life of your servos. You also have to remember that the DX3R's electronics were designed to operate at around 6V Max. You're adding considerable voltage there that could potentially damage and shorten the life of your transmitter. Not trying to be a downer here but there are consequences to what you guys are doing. Why do you think you need an adapter for US electronics in countries that use 220v instead of 110v? Granted that's a bit of an exaggerated example but a valid one.
