T-Pain Is On A Boat: Re: [Electric Boats] Re: Turnigy Watt Meter

This same unit is sold as a "Watts Up" meter. I have one and it was invaluable for evaluating different props on my sailboat drive. Be sure to use quality connectors, though. I first used the flat spade connectors from the auto parts store and they heated up noticeably. The gold plated bullet connectors used in the RC world work much better.

There are a lot of interesting products in the electric RC hobby - including motors and controllers that can propel a 20 lb. plane straight up.

I finished the Turnigy Watt Meter modification today. It works great so far. now I have amp draw, voltage, watts and some other information at the helm. It mounts next to the compass and is held in place with a nylon wedge and Velcro. When not in use it is covered under the compass cover. I'll add some photos to the Lotus Flower folder.

Turnigy Watt Meter $30, Bogart shunt $30, misc. wiring and connectors $40, time scratching head - priceless.
