Tim...no problem man, glad I could help with the numbers. Unfortunately, I am pretty much out of comments as you are delving into an area that I have not seen tested, so you will be pretty much on your own. I am sure the model will fly on lesser setups as it glides well and has long legs on landing, even at my weight of 43oz AUW with the 1950 pack.

So if you keep it at 30oz or so, which seems pretty light seeing how mine was 29oz without battery, you just cut down a bunch of weight. The only thing I see on numbers is you may have more TTW with a lighter setup, but the output, and more importantly velocity of the thrust will be much lower, hence your top speed will decrease. RPM will be 20,000rpm less than what I would call a normal setup...that's quite a big change.

Anyway, good luck and let us know what you wind up doing...I would like to see some comments on a lesser setup.
