I also have a Lazy Bee with a Magnum .15 engine. I've had it for about 5 months and it's a very fun plane to fly. I did not build it so I can’t tell you how they are to build. I purchased my used and it was an ARF. It performs very well at slow speeds and it can be launched from any patch of grass or by hand. I’ve got about a gallon a fuel through mine and since I usually fly at 1/3 throttle on the .15 engine, that’s a lot of flying.

The lazy bee is very stable and surprisingly tough. This past weekend I flew mine into a power line on my brothers farm. It shattered the prop on impact and the plane tumbled approximately 30ft to the ground. The only damage was a busted wing tip that I repaired in about 45min. And of course the 2 hours I spent cleaning all the mud out of the engine. The bee is now back in the air.

I would highly recommend the Bee to anyone who is interested in flying. One thing I will say is that a .10 size engine would be plenty because I almost never use full throttle with the .15.
