Just going through some videos from last year and this was one from Sept 2018.
The S6 started having problems trying to hold in gusty wind.
Problems start around 2/3 mins into flight and the wind picks up.
To be fair this test was done in a back yard and therefore lots of turblence.
But it is a test I do on all my quads to get a idea of how they handle the conditions.
The S6 seems to be slow to react and them slow to brake from over corrections. I think a lot of this could be addressed by fine tuning the pid’s . But sadly be do not have any software from wingsland to adjust this.
To be also fair this test was done using stock props, but using a 2s Turnigy 1600mah standard lipo so was heavier and therefore would add to trying to recover in the wind.
