Smack that hoe!

In the garden dept, no less!

The picture is not of myself, Yes I'm big guy but I thought the picture of the T-shirt was funny ?
Who are you to tell me what's cool and isn't anyway, you have a kermit with a kalashnikov,what the hell is that ?
I changed my avatar just for you and you can smooch the right cheek.

I'm hearing you Brian, I had the regulator laying around and thought I'd play it safe with Traxxas TX.

a 2100mah fit into my m11. it even has a alarm when it hits 9 volts!!!!

So, to do this on the DX3S, I should get a BEC. I've never actually owned or used one. Do you program it via a PC or card?? What Voltage do I set it at since my radio uses 4AA's? 4.8? yep, I'm a ri-tard. Also, I can use whatever MAH I want... as long as it fits inside right? And 2s? 3s?

I'm using the little blue BEC here; http://www.castlecreations.com/products/ccbec.html

I think mines set at 4.8-5.0, programable via the PC just like the ESC's.

And I'm currently using 3s 20C 800mah packs and they last about 6hrs non stop. I carry a spare lipo in the case just in case, they were 6.00- 7.00 a peice at HC.
I would look for somthing with higher MAH, I will next time I need new packs.
You can easily make more in the battery compartment via a Dremel but still be able to reinstall the 4cell AA tray if needed.

To honest w/you, this mod is not for everyone. If you only use your TX say a few hours a week I'd stick with the AA Duracells and save yourself the work and hassle.

The biggest issues about using lipos in a 4-cell transmitter are 1) the use of a BEC or any regulator will not let you know when the the lipo is at LVC, and 2) a BEC can fail, sending full input voltage to your radio.

Personally, for 4 cell radios, just get some low self-discharge NiMH cells. They are the next best thing compared to lipo without the shortcoming.

Thanks for reminding me Brian, I have some low self discharge NiMH from HC I have yet to try. If they work well in my other TX I might change everything back in my Pimp TX.
