Nice watt meter.
My favorite feature of the Astroflight meter is that it does not need its own internal battery to work it uses the power from the lipo you plug in to power itself. All electric modelers need to have a watt meter. It is a great tool when testing motor and prop combination and also to diagnose a weak lipo battery. Only criticism is that I had to cut off the supplied connectors since I only use Deans plugs on my models.
I give this product 5 stars. Review by slusarczyk, don
