Hi Ernie!

VV sells the RCEXL switch 3 ways. The first is stock (19.95), w/the 4th lead going to your battery/power source. The second switch has been modified internally (very easily done yourself BTW, if you can solder?) to use power from the lead that also controls the switching function (29.95). 4th lead removed. The third, is the second switch modified to drop/regulate the voltage (34.95).

Either of the second 2 could be said as having a BEC? I would suspect your hunch about needing a load placed on it while measuring output it is spot on.

I suspected Valley View was modifying the stock switches in house, but now I see them available elswhere? So now I wonder if Rcexl has started offering the different versions, or if others have decided to mod the stock switch in house as well? Anyone know for sure? -Al

Edit: I've been using home modified (per directions supplied with the switches) switches since they came out with the newer version in the hard case (vs. the original supplied in shrink wrap). They work exactly as they should. Myself and others I know are using them without a single failure.
