Digger ___ you may want to take a second look at those Ultra Lite tires!!! I don't care for them on a 9 lb plane and the 300 is 14 +. With the gasser it may be closer to 17 lb. I have a Moki 1.8 on mine but it's a 300 not the XS. I think you will enjoy the build and I'm sure you'll enjoy the way it flies. ENJOY !!! RED
