I had the MA updated with the .500 firmware and have realized that the speed was slower (60kmh downwind, 50kmh upwind in sports mode, 23-25kmh in pmode). I then thought a little about the speed recently on the .400 and found the speed was pretty much the same recently. I remembered that even the spark used to be so much faster in both s and p (when obstacle avoidance was off).
When comparing the air to its the state as new, the speed in sport mode has dipped some 7-10kmh and 3-7kmh in pmode which seems a lot.
I thought about the factors
- Temperature - I have hit 70 kmh during summer and at 27 C in shadow in the afternoon with a lot of sunshine the air would not have been as dense as today at 20 C in the evening.
- Wind - today was very quiet and I could not feel the wind much at all. Having said that the speed difference was as significant as when I have hit 70kmh, only much slower in both directions.
- Props - have not been changed during the course of the 6m+. Although they look pristine and am very careful, when comparing them to the spares, the tips seem to have a ever so slightly different angle. The rest of the props seem OK. I always thought that the case for the air bends them a bit, but never really got to see them "damaged" so to speak.
- Obstacles - I tested this in an open field (the same where I hit the 70kmh) at 14+m high, I do not think the obstacle avoidance would have slowed the aircraft down for safety, or would it?
Did anybody have any similar experience?
