this thread is much more friendly
so far I have installed 4 VW in my planes and there just a little extra cheap insurance at 6$ ea, got some of mine off ebay,they all jump when I put a load on them, but return to the base when I let off the sticks.
the thing I like aout them, is if I am tooling around the shop I just turn on the planes and check the charge levels, if I notice there is a low charge on one particular plane,I just hook up the charger, after sitting for a while I stumbled upon one of my planes that was really low,even if I am not flying for a bit I like to keep the batterys up, and not let them drain down too low.
a couple of examples of mounting location I put mine in the cockpit so there easy to read and not placed on the side of the plane where they can get dirty or dammaged
