My take on this is that if you brand "X" turbine and it is performing like you want it to, be happy and go flying. Don't get bent out of shape if you bought a fish scale from Dollar General to test the thrust and it is putting out a 1/2 pound of less thrust than what it is supposed to.

There are too many variables here, so go fly, have fun and be safe.

Going to be 81 here tomorrow and guess where I'm going to be and it is not at home fretting if I'm getting the claimed thrust.
