I have the MKII and unless you have really old, weak batteries I don't see a reason to run the 16x8. The 16x8 gave me about 85 amps and was making everything very hot, and I would occasionally get a squealing and loss of sync on throttle up. When I went to a 15x8 flight time increased, speed increased, and everything played happily together.

Thanks guys. I'm going to give that Protek 15x7 a whirl. I do have another Xoar 15x8 standing by.
I forget the wattage I was pulling on the Xoar but guessing it was in the 1600 range with 65-70 amps.

I like it just ahead of neutral. No reason to run these planes tailheavy IMO...they 3D great even when nose heavy.

The Pro-Tek 15x7 will likely get you about 1400 watts. Not quite as nice as the Xoar 15x8 but plenty.

I metered it at 1500 static. We'll see. It's still a boatload for this light plane. Have to spend some time getting it set up nice.
Thanks.

I'll have to have you help me finalize my setup to get it really smooth! I need all the help I can get.
