Ryan 26cc First engine test

First ground test of my new Ryan with the CRRC Pro 26 cc petrol engine, so still with the cowling off. My first experience with petrol engines. The model is from Black Horse Models and has a 2.3m wingspan. Still running in so using a 16X8 wooden prop and 25:1 petrol to two stroke oil ratio. Carb set to rich until run in a couple of hours more, will then start to lean up and change to 35:1 fuel mixture. the engine has previously been run in on a test bench for about 3 hours at just over idle, keeping the temperature below 80ºC as recommended by my model shop.
