I understand what your saying 100%. I stopped running my 8711 on the lipo because I was starting to use mech braking on my 1/8 scale electrics, so I didn't want the added weight and complexity of 2 servos, a battery, PT and so on.

I know there are downsides to running a Lipo in the 3R, but if I happen to dump the transmitter, then it will give me a reason to get the 3S. But ya can't tell me there isn't any excitment in pushing the limits :-)

These radios are such a small draw heat is not an issue, and about the voltage fresh good AAs will be well over 6 volts. If your really worried about the extra voltage hurting something just use a 5 cell flat RX pack.
The reason we want to use other types of batts is because we allready have them and they are rechargable.
No one can argue a 1700mah pack is going to last longer and be cheaper in the long run than AAs.

I doubt horizon would warentee my radio anyways, The wheel isnt stock, the trigger has been melted and good lord like every hobby product ive ever owned I took It apart.

LOL Hi-voltage servos, All Good servos run fine on 2s lipo

OK its been over a month since the last post, anyone had any problems with this yet im def interested in trying

This is a bad statement, because the AC Frequency is different.

Radio's are DC voltage, i do agree, overvolting a radio doesn't sound smart to me. specially by this much.

are li-po's still working out ?

I will I run 2600 NiMH AA's in my radio (not a DX3R), and unless the lipo math on mAh applies here, 2600>1700... As for cheaper, 4 of the AA's I use came free with my charger

Now, I will say it would be more convenient to hook the pack up to my charger at the track in a pinch rather than borrow or buy AA's...

Who cares how long it last..i wana know if anyones had there radio melt in there hands yet. Has anyone had any problems doin this yet???

Wow this thread is dead. Anyways JGruber sold all of his racing gear a month and a half ago but his DX3R with lipo was going strong. I am too not one to fix whats not broken but am for sure curious. I am using NIMH rechargeable batteries and yes they are a little heavier however I see no reason to go with a lipo battery for weight reduction with the DX3's being so light as it is.

hey i have a middle of the road solution. i run the Enerdizer lithuim aa's and i love them and they last for ever in my radio just switched to an 3r. i know these will pull over 12 hours in a m11. and that is 8 of them.

I'm looking for some feedback on what people were doing late 2010. my dx3r has been running on 4 NiMH bats successfully for some time and Im wondering if it is worth the mod. It literally takes 5 min to charge these batteries and it last for 6 hours. To me this seems more than ideal. I labled them to rotate the charging position in case they are giving a false charged signal to my charger(charging one or two of the batteries leaving the others untouched). I'm not really sure if this makes a difference with NiMH. Input and "mochary" is taken well, to a certain extent.

I've used everything from the cheap NIMHs from Harbor Freight to premium Sanyo Eneloop AA batteries. Oddly enough, the Harbor Freight Nimhs lasted longer, and charge cycled more often than before rolling over dead than anything else. With them being so cheap, never saw a need to go LiPo with the TX.

I have been running over 8v in my DX3R for more then two years with zero issues.
I did it originally to gain radio range which it did very well. The comment made about the radio only being able to handle 6v is completely untrue there is not one component in the radio directly related to the input voltsge rated for less then 15v and the radio could never generate enough amp draw to even warm up a lipo.

As with any lips use cation should always been used but in this case as far as I have been concerned the higher voltage has only benefitted and saved me from buying a futaba.

LIFE batteries are more stable than LIPO and a better candidate for a TX than LIPO IMO.
Also @ 3.3v per cell a 2s LIFE is closer to 6v than LIPO

a switching regulator would not cause heat problems, and they don't interfere with cheap chinese radio so I would be very disappointed if they interfered with a Spektrum.

Got to say I agree with you on the using NiMHs though, people see the mods we used to to back in the day with AM/FM radios and think "boy, that's a good idea" not knowing enough to know that the old radios really benefitted from such a mod, whereas it's counterproductive in all modern 2.4ghz TXs as most run on a combination of 5 and 3.3v, which has to be got by regulation. Because radio manufacturers are cheap, the regulators in such radios are invariably cheap linear items - rather than the vastly superior, but slightly more expensive switching regulators - which struggle with no heatsinks and in a sealed case to dissipate the unwanted energy even with alkalines and fully charged NiMHs, never mind a lipo. This is probably not so much of an issue with the 4 cell radios but 4 cell makes it even more unnecessary to run a lipo.

LiFe is a good idea due to its lower voltages, but LiFe's power:weight/bulk ratio is quite poor. There's just no need for a Li of any kind.

I’ve always wondered about the higher voltage providing more range with a 2.4GHz transmitter. I don’t know for sure about the 4 cell jobs like a DX3R, but I do know the 8 cell DX series use a regulator. And since they are all based on chips, I suspect, but again don’t know for sure, they all are regulated to standard chip voltages as you mention. Really doubt if they are using custom chips, it’s not like 2.4GHz components weren’t already readily available.

Which would seem to preclude any possible range increase from a higher voltage battery much past 5 volts, perhaps 5 plus any associated regulator drop out.

If so this can fairly easily be accomplished in a DX3R by adding a 5th nimh battery, as there are 2 additional spots under the cover past the standard 4 spots. Or 4 AA lithiums with no mods as some do. With little risk of killing the batts (nimh only obviously) by accidentally leaving the radio on, or having a lipo puff damage the radio.
