I purchased an ACE DIGIT PACE II some years ago for charging, and cycling batteries at
home, and a HITEC CG-335 peak charger for use at the field. The HOT SHOT charge button
has certainly been a help when one of my hot shots needs charging at the field. Unfortunately, the HITEC CG-335 is no longer made. HOBBICO makes two units that would
be chargers to look at. The DELUXE POWER PANEL II has a glow starter charge button, and
the HOBBICO PEAK FIELD CHARGER would do a good job charging your tx and rx batteries
at the flying field. Both of these units are for panel mounting into your flield boxes. The main thing to keep in mind is to have the chargers you need for all occasions whether at home, or at the flying site. The market place has a good variety to choose from. Good hunting.
