I've been flying one since February. Lots of fun in the air. Fairly fast and goes where it's pointed. Landings were terrible at the CG shown on the plans. Moved it back 5/8" and now lands nicely.

Kit is well engineered except for the gear mount. Way too weak. Otherwise a nice design that builds fast and straight.

I've powered mine with an OS FT160. Weighs around 12.5lbs. No ballast required with the twin.
