Well, we knew what he meant.

JFYI:

ESC=Electronic Speed Control
BEC=Battery Elimination Circuit

Most all of our electric planes today use an ESC. I do remember some way back that some used a simple on/off switch or a rheostat. I never gave electric power a second thought back then. Many of today's electric planes use a BEC. Some ESC's have a BEC built right in. Other ESC do not have a BEC and if you want to use one you have to buy it separately and wire it in. Awhile back I suggested that Castle Creations make their non BEC equiped ESCs with a plug that could be used without having to hard wire the BEC in but I don't think that went too far. I still think it's a good idea.
