RE: Faster charger for the DX7
I’m looking for a cheaper wall charger right now. But one day I’d like to get something like that. It's just the funds are a little depleted after buying the Radio.

After forming the pack in my DX-7 I charge it using a Sirius Pro Charger Plus fast field charger.

And Scriptt, if you plan to stay in the hobby for any length of time, get yourself an adjustable rate charger. And watch the polarity when charging Spektrum/JR Tx's, negative is on the center post.

RE: Faster charger for the DX7
G'day Mate,
I charged mine, & have not charged it for 4 weeks, & I have flown for 6 hours 15 minutes, over that period, & my TX voltage is still at 10.3 volts, it has a 1500Mah battery, in a TX that uses about 100Mah, that's about 15 hours of flight time.
I just reset the interval timer in the TX, after I charge, & it tells me how long I have used the radio.
No need to charge every week before you fly, It has heaps of capacity.

Hey Galen, I also have a Sirius, but have been using my Alpha 4 at C-10. Do you find the Sirius Fast Rate on the NiMh's detrimental ?

My not so great results were with 1650 Hydramax batteries that had not been given proper forming charges. The Limited Edition charges at 2 amps and that was likely too much for those batteries. Since getting larger 2700mah packs from Hang Time Hobbies (No BS batteries) and properly forming them using the new Sirius forming charger I am getting better results. I haven't flown much with these new batteries so I don't have as much experience as I'd like, but so far so good...
After forming the NiMH pack in my DX-7 I have only fast charged and so far it's worked really well. I flew all afternoon last Sunday and the voltage was 10.1 the entire time... I was kinda surprised at this -- my 9z with a 2700 mah NiMH battery hasn't done as well...

RE: Faster charger for the DX7
G'day Mate,
I used the wall charger for the first charge, then I cycled it twice, using the wall charger & an ACE discharger, the last time I charged it, I used an ACE Smart charger.
I followed this procedure, http://members.aol.com/davthacker/balancecharging.htm

RE: Faster charger for the DX7
It is very easy to convert a wall wart that has the center conductor positive. Just cut the charge leads in two and then solder them back together reversed; or, put a DPDT switch in so you can switch it to be in either position. If you do modify it, it is a good idea to tag it so that you remeber which way it is wired up.
