I had the Patrick Extra. I was flying it on a BME 44 and the weight was in the high fifteens. You would probably come in around 15 or somewhere in the high 14's on the Moki. It would be OK, but not graet on your 1.8.

I took my Moki 1.8 and put it in the Dave Patrick Edge. That's a really good combo. I am just under 14 lbs and it flies great. The prop on the Moki 1.8 is the Mezjlik 19x8. This is a MUCH better setup for your Moki.
