Thats why I put the "if you are serious" comment in my post. If you are playing with 100W setups then you probably don't need it. If you are playing with 3000-4000W setups like mine and can destroy $1500 worth of gear in a few seconds, a $150 meter is well worth the investment.
Fair enough. And you're right. And in addition to high-power apps, you're also flying high-performance, no? Probably putting more stress on the system than most people would? If I had that sort of investment in the air and I was pushing the limits, I'd want as much info on its performance as I could get too.

But like I said, I think about 90% (or more) of electic flyers are in the 300 watt or less category. There's "nice to know" info, and "need to know" info. And for most people, if you allow for a safety margin (I try to go 20%) with your static results, there shouldn't be any problems.

You are quite right that most will never care, or need to. Since he didn't really specify what size models he was using I just wanted to post another option even if most would consider it overkill.

More and more guys are running high power setups. At our field there are a number of 1200-1800 watt setups, and more showing up all the time. Its getting very inexpensive to drive a 1200W 40 size model electrically now.

I think in a short while you will see a 1000W setup be fairly "mainstream".

I do agree though that for the simple "watt meters" that the Watts-Up is the best buy and most useful. Prior to the micro-loggers we were flying with watts-up on board to establish our peaks in flight, this was probably 3 years back though
