I have one of these cool mossie's I have only flown it indoors & it flies great, it sounds good with the twin motor sound with everyone wanting to stop & watch it scoot around the basketball courts.
The area we fly indoors is 2 basketball courts side by side with around 6 metre roof height we have to watch out for a cable going across that holds the dividing net between the courts but beggars can't be chooser's & we have a great time flying all sorts of small electric models once a month.
