Program your Corona SBUS servos with this nifty little gadget!
This is the Corona CSBP-1 SBUS servo Programming Card. With it you can set servo direction, change what channel operates the servo, adjust left and right travel of the servo separately, set the neutral point and test the range of a servo. The manufacturer claims It's also a lipo battery voltage checker, but our testing found it to be very inaccurate.
As far as we know, this programming card only works with Corona servos.
