it keeps saying system check and goes to a screen full of ?????? marks. I just got the charger today and haven't even used it yet. Has this ever happened to anyone else, and what did you do to fix it?

That sounds bad. Contact A-Main's customer service.

I have one and the only problem I have is that one of the buttons doesn't make contact all the time. It's the Start/Enter button. The only time it's a hassle is when I want to retrieve a profile when you need to press that button and the + button simultaneously.

Otherwise it's a very good charger.

Mine did that. I ditched it a long time ago so I do not remember the exact procedure, but there is a button sequence to hold down when you plug it in that puts the charger into a different mode. It will allow you to flash a different firmware to it which is what fixed mine. I had to go back to an old version. Mine started doing that when I was arrowing through the numbered storage slots. When I hit a certain one it flipped out and that was all she wrote. I had to reflash.

You have a few options depending on where you bought it - you can post a ques for Junsi here, it may take a day, but he does answer ques pertaining to probs with iChargers -

If you bought it from Progressive, call and Dave will tell you what you need to do. Dave is such agreat guy, he'd prob help anyway. I think EPbuddy will do the same if you got it from him. If it came from HK, I'd post on Junsi's thread on RCGroups.


Its prob simple....

good to know there is support on here for the charger. I sent it back to amain. they are sending me another one. I guess I won't do the update on this one and see if it does the same thing. im gonna pm junsi first though and find out what to do if it does happen.

Yeah, that was one factor in deciding to buy my 3010b, knowing support was pretty good.

Glad Amain took care of it.
