I need a recommendation for a digital fish scale to measure engine thrust. I know that RCIGN has used them. I see no other way than to get accurate (as possible) date of these figures when changing props and fuel etc. I'd like one that can measure up to 50lbs. Most of the fishing sites have one made by berkley. Anyone have an idea?
I don't care for RPM numbers for other than tuning my engines, but I do that by ear and checking the color of my plug.

I got mine at Wal-Mart. I believe it is a Repella brand and digital. I haven't used it yet to check thrust with, but it's dead on at up to 20 lbs so far. I think it also goes to 50 lb.
