Hey all,
I just finished installing my spinner and went to take it for a spin - no pun intended. At about 50 kts, the engine rpm's vacillated and the Dynon EM went off. I was going to fast to look down so I am not sure what the warning was about. I pulled back and went back to the hangar. I have 4 hours on it so far; new XP 0-360 and lightspeed. My first thought was something wrong with the engine and that the engine had lost power and regained it but then I asked the airport manager and he said it sounded like a surge.
It is possible that manually twisting the prop may have squeezed the oil out of it and allowed the engine to over rev. I did not cycle the prop prior to take off.
