There were 20 trikes, 1 hang glider and 1 UL plane. In the afternoon visited us a little tornado. 4 trikes was damaged, but all was able fly home after repair.
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?
