I have a top flight 1/4 scale P-47 D razorback with a desert aircraft 50 cc engine. It’s nearly impossible to find this particular plane or any replacement parts in the US since it’s been discontinued. As you can imagine, especially if you are dedicated to the hobby, flying it can be a bit nerve-racking, considering a crash will end all that. I have always used ZOAR propellers. For example, I once used an another manufacturer, propeller, which are normally reputable. This propeller broke while in flight and severely damaged the cockpit canopy and part of the cowl. Thankfully, I was on the last leg and Landing. I don’t use any other type of propeller. They are perfectly balanced, and are ready out of the box. The propeller that I am commenting on is for a skyline 182 Cessna. So far it has not let me down.
