Spektrum Dx7 Charger

The included charger with the DX7 is a 50 ma charger - not big enough to charge the 1500 mah trans pack and/or the 1100 mah flight pack overnight - for a NORMAL C/10 overnight charge rate the charger should have, like a 150 ma and 110 ma dual outputs. The VERY SIMILAR JR XP7202 radio system comes with a dual output 110 ma charger. Has anyone bought a DX7 and gotten a 110 ma or LARGER dual output charger in the package??

Mine came with the same 50 mah charger. I made up some leads with the proper plug on the end, to use my Multiplex LN-5014 charger on the TX as well as the RX packs. I can't do them at the same time, but I can set whatever charge rate I want and know that it will shut down when the pack peaks. I usually charge my 1500 NiMH packs at about 200 mah. There are some chargers that can charge two different packs at the same time, but I can't justify one yet

I can still use the factory charger to get the TX and one RX pack going, then switch each to the faster charger as it tops off each pack.

Make sure you get the polarity right for the charging plugs!

Thanks for the reply - but when you spend $350.00 on a radio system you figure you should get the corret charger......no??? I would think they realize they have a problem and correct it - my radio system was shipped from the factory last week!!

It is not all that a big deal, since so few actually use the wall chargers any more...I leave mine on for a 24 hour period and top it off with a fast charger once in a while, at about .5C.

G'day Mate,
No big deal, charge it with the wall charger, for 30 hours, then you won't need to charge it agin for a long time, you can expect about 15 hours flight time from the 1500Mah HiMh pack.
I charged mine with the wall charger, then cycled it, twice, & I have not charged it for a month, & I fly every weekend, & it is still at 10.1 volts.
The DX7 only uses about 100 Ma, during use, around 40% less than a conventional TX.

The change was made a long time ago -- soon after the Feb 2007 Horizon note that's mentioned above. I bought one last September and it had the dual 110mA charger.

There's nothing wrong with the 110 mA wall charger for most people. Just put it on charge when you get back from flying and leave it overnight. The 1500 mAh battery has enough capacity for at least a couple of flying sessions with loads left over.

Sounds like an error to me. Have you contacted Horizon?

It's funny that no one on this thread mentioned the change was actually made if it was that long ago.

Yes. It's over a year. All the old DX7s with low rate chargers should have worked their way through the system a long time ago. But doberman says he got his "from the factory last week." How do you buy a DX7 from the factory anyway?

I prefer the original charger-- you plug in the TX and leave it -till you want to go fly-
The guys with short battery life on their tx --I would bet - tried their quick chargers for first charge - and screwed up the cells . NiMh like a nice long soak for initial charge and for future charge - the walwart is still the best. The newer charger is fine - anything under 1/10 of batt capacity

Your lucky you get a charger ! In the UK (the land of paying tax on everything) we don't get a charger with the DX7, if you want your TX to work you have to buy your own charger. So thats a $450 DX7 full kit with 4 servos but it won't actually work !

Thanks Horizon
