Reproducing is pretty easy. If i set 6 m/s as speed in set speed command it doesn’t take it and goes at 2 m/s. I reported this since last year i think and here and there people show up with same problem.
I wrote about the problem once it was released in beta test, if i recall well it was first seen on 4.0.3.
Ultimately i brought up a problem, if you don’t need this kind of feed back, it is fine with me and will not do in future
Hi David,
I’d like to see the dataflash logs if you’ve got them. Basically we just need to be able to recreate the problem in SITL (the simulator) in order to figure out the details of how it’s happening. I’m reasonably confident the issue should also show up in SITL if we can follow the same steps.
Same problem for years, maybe it is worth taking a look and don’t let it drop as usual.
Well, as @Corrado_Steri said…
Changing WPNAV_SPEED from 3m/seg to 3.1 m/seg SOLVED THE PROBLEM!!!
*Note: wpnav_speed is ment to be set in cm/seg
…there’s something about round numbers that is making wayponits navigation go slower…
And there’s also something about the way you take off as I said before…
Takeoff secuenses (with wpnav_speed=3m/seg) :
Take off in loiter, hover and then switch to auto mode >> wrong navigation speed (slower)
Take off in guided, hover and then switch to auto mode…
