burns .63 amps at 12 volts ++++++++++++++++++++++++++++
I would have expected a larger drain under typical flight loads - did you give it some "resistance"? Please be real careful about lowering mechanisms that may fail /burn out /trip at a bad time. A belly board contributes very little (relative) to lift - particularly at the typical deployment angles. Unlike flaps, you can pop it up at any time if you need to. Someone reported on the impact of a belly board on the take off roll - that told me enough. I presume he was doing C&B's, why else would he know how the bird accelerates with the brakes on? Steve J
