-- "I spent an idyllic morning yesterday flying the Waco UEC at a site at Perris, California. It is an excellent site with good green grass this time of year and the conditions were perfect - sunshine, but with still, cool air. The model climbed in a wide circle and remained overhead the entire time. This enabled long engine runs and really spectacular flights, enjoyed by the many other flyers. I know the engine well by now and can get it started very quickly despite the tight cowling and lack of access for priming. It runs the same each time with no fiddling with the needle valve or compression required. It has achived my goal of a very realistic scale model that can be easily flown again and again with a minimum of maintenance.
All told, the pb .33 is a superb piece of engineering and craftmanship and is my favourite engine, the best I've ever owned. I think it has just reached the point of being fully run in and expect it to last for a long time.
Bob."
