RE: Has anyone converted a Sig Rascal 40 -Glow to Electric?
No, a programming card is different from a BEC/UBEC.
The programming card allows you to program, or configure, the various settings on the ESC (electronic speed control).
A BEC is a regulator that converts the main battery's power into a low enough voltage for the receiver and servos. UBEC is a type of high-capacity BEC used in larger planes, or planes with high-voltage batteries, or planes with lots of servos. The built-in BECs in ESCs are usually limited to 2-3 servos and a 3S LiPoly.
