Hey Rick:

This subject has been raised quite a few times in this forum, so you might want to run a search for either "chargers" or Graupner Ultra Duo" in the jets section to see some of the past threads. You may also want to take a look at Eddie Weeks Rig posts since he wrote one not too long ago in which he addressed how he charges that monster.

I have an Ace Digipace II at home and a Graupner Ultra Duo for the field. I am about to add a Hitec CG335 to my collection since the Graupner only has one output that can run automatically. This still will not be an ideal combination in my opinion, but it's a pretty cost effective solution for now.

You may also want to check into the Schultz (sp?) web site since they are the company that make the Graupner chargers. Their chargers cost slightly less and have more current (no pun intended) software.

Good luck.

Antony
