Rotax 916is First Long Engine Run (10min)

First long-ish run of my 916is to get the oil temp up to 180 F and also to measure the sideways movement of the exhaust pipe to determine the required exhaust pipe hole in the cowl to avoid pipe-cowl contact. (and from the videos taken it appears that the tip of the exhaust pipe moves about 1/3 of its diameter to each side during startup, so I will make sure I have about 1/2 exhaust pipe diameter of clearance on each side to avoid contact)
