Default Good Thrust to weight ratio on my profile F-18 EDF

K I just did some testing tonight. My EDF unit is putting out about 230-240grams of thrust. It's a GWS 6 blade 64mm unit. 25 amp ESC, 11.1V 1500mah 15C lipo. The whole plane with the battery weighs about 470 grams. Is this decent? I know the model is a wee bit heavy, it has already flown but I'm curious what the average thrust to weight ratio on a foamy is. Obviously 1 to 1 one or better would be awesome.

I've never measured for thrust, I go off of watts per pound. Do you have a wattmeter?

Here is a nice breakdown of what works.
