I have one and it runs well. Won't turn the lake to steam but it goes fairly fast and handles very nicely. Unless you are an experienced model builder, or have a friend with some experience with plywood, I wouldn't recommend the kit. The instructions are among the worst in the industry and the die crunching on the plywood is as bad as I've seen. I have been building for many, many years and overcame the building problems. They recommend a 3 oz. fuel tank. If you can find that size tank you will have to acquire a large shoehorn to get it in the pylon. By the way there aren't any 3 oz tanks on the market. I had to modify the pylon to take a 4 oz tank. The 2 oz that fit wouldn't get past the center of the pond. With some care it can turn out to be a nice boat that runs well and handles nicely. Use something other than an OS .10. That engine has a wierd fuel and needle valve dual intake manifold. Any other .10 will probably work as well. An OS .15 should work just fine. Take plenty of time to align the firewall properly. You might want to consider a different method of hinging the rudder as well.
Now that mine is done it looks nice and I'm enjoying putting around the pond.
