I made a charge adapter for my spektrum radio (pics) - RC-Monster Forums

Yea I am in the middle of doing the same thing for my DX3R, but have not found a suitable plug to install on it. I was thinking of doing something very similar with a TRX plug and using it with one of my battery chargers. I already have a 5 cell 6volt nm pack for it. I really need to get off my butt and Get-er-done. Nice work.

The RadioShack 'M' or 'N' plug works (can't remember which); just test fit one. Just be aware that the "sleeve" of the plug into the Radio is the + terminal (usually the sleeve is the - terminal).

Yea thanks BG. I remembered that you made this point in your earlier posting. I think that is why it has taken me so long to get it done, because I am leary of making the connections wrong and frying something in the process. I will get it done soon. Thank you for watching out for us.

I wasn't too sure of the polarity (I had a good assumption) so I made sure I had the polarity right before actually putting the battery "pod" into the remote. That way I couldn't smoke anything.

I dont have a volt meter, so I hooked it up to my hyperion and if the polarity was wrong (which it was) it would read "reverse voltage". All I had to do is switch the two power wires around and it works like a charm.

Yes but are you charging the battery pack in the radio, or are you removing the pack and charging it seperately? That is where the problem is. The charging port is wired reverse from regular hookups. From what I understand the plug that goes into the radio is reversed from the normal plug. Normally the plug is + in the center of the plug, where as this port is - in the center of the plug (only for the Spectrum DX3R radio), which is what we are working with here.

I did what I said above to find to polarity in the jack adapter I made. My spektrum manual actually showed me the polarity of the charge jack in the remote.

(I am charging the batts in the radio, see pic)
