Hi Tom, The kit is very good and easy to assemble. As i was one of the first to build this kit i had to do modifications to the build in several places. The fire wall box top corners were hitting the engine cowl on the front top corners, therefore i had to slope the top of the box at a greater angle. This is just a small example. Not built the Ziroli kit but I think this one is a better build. Flying is brilliant, stable easy to fly and does not tip stall. The biggest problem with this plane is the engine. I had a RCGF 61 in it which had great power but overheated. Changed to a Zenoah 62, doesn't over heat but could do with that little more power. If you can afford it the Roto 85 twin in line would be great for this plane, but even that I've hared that the rear cylinder overheats. Overhaul the plane is great. Thanks
