One modification I did to my Razor 3D after the maiden flights was to add a MaxCim Charging Harness to allow me to re-charge while keeping the wing on and the batteries installed.

I have found this feature to be invaluable for full day events. You can set up your planes in the morning and keep flying or recharging all day. You simply taxi into the pits and plug in your charger after a cooling period.

So far, only MaxCim Motors seems to offer this convienience. SR Batteries also sells the PowerPole-style fuseholders but not as a complete assembly for charging.

These pictures show my modified MaxCim Charging Harness for using Dean's Ultra connectors. I simply plug the harness in between my controller and battery. The 40amp ATO-style fuse can be moved from a "RUN" position to a "CHARGE" position that disconects the controlled while charging.

Plug-n-play! Yeah, that's what I like.
