I did the engine oil leak test. It was first flight after repair engine. The owner of LZDV airport told me: You are crazy! You did the engine test and you used it at full throttle with 45°climbing...
How else could I do the test?
You can see at 8:40 he had a problem with katabatic wind what mixed to "normal" wind. he did good decision and went around. First climbing surprised him and next he didnt use a full throttle for take off.
