Prop Wash

chip chipman · Mar 9, 2015

Has anyone experienced errant behavior with the AC due to prop wash?I was flying down a driveway , houses maybe 20 feet apart and noticed the the inspire was prone to wandering making it challenging to maintain a straight course. Or maybe it was connection problem or, or, or maybe it was (I hate to think) PILOT ERROR

Was the visioning system active?

I assume it was. I was toggled to "P" and was given the all clear to fly (RC light was green).

It could have been picking up shadows or other thing? Just a guess...

So do you think prop wash- if it exists at all- is probably not a factor?

Could be but it handles prop wash pretty well. I have flown it in doors which would be worse than you describing, imho.

When you flew indoors did you get close to any walls and if so how did the craft respond?

I didn't get close to walls but was only about 4' off the floor. It kicks up alot of prop wash indoors at that height.

But it still handled smoothly or did it start to react to the wash- do a degree that made you more attentive to what it was doing?

On Phantom forum a lot of crashes were blamed on prop wash ,but in my opinion it is great overreaction. Multi rotor prop wash is rear thing.
I did my own tests with manual training craft and never experienced single crash cost by prop wash; you if it goes down really fast it wobbles ,but could be managed.
In you case my guess would be - sadden wind gust
- or pilot error ( for example one could be good on flying inside the room with those little quads ,but once you try to fly through the doorway ,you get nerves not to hit the frame and it will become pretty challenging task ).

Propwash has an effect while descending fast, not by hovering around at a given alt. Was likely the vision positioning system being confused by the pattern on the ground.
