Stuart Quinn-Harvie 1 Posted May 6, 2019 Share Posted May 6, 2019 Evening all, I have seen a wonderful aerobatic thing performed by a funfly model. It was this: Aeroplane slows down into wind until pretty much stationary relative to ground, then ( I think ) all horizontal control surfaces go up and the aeroplane descends vertically whilst parallel to ground until surfaces re centr, engine opens up and it flies off. Anyone know what this is called and how it's done? Cheers All. Quote Link to comment Share on other sites More sharing options...
Alan Gorham_ Posted May 6, 2019 Share Posted May 6, 2019 The manoeuvre is known as a harrier for self-explanatory reasons. Quote Link to comment Share on other sites More sharing options...
Nigel R Posted May 6, 2019 Share Posted May 6, 2019 Descending vertically, "elevator" Harrier is slow flight forward, very slow, at around 30 to 45 deg pitch. Partially hanging on the prop. You will require a cheap foamie 3d model to practice either with Learning the 3d maneuver set is like learning to fly all over again.

Alan Gorham_ Posted May 6, 2019 Share Posted May 6, 2019 Haha well you can tell I can't fly 3D then! Everyday a school day. Quote Link to comment Share on other sites More sharing options...
Nigel R Posted May 6, 2019 Share Posted May 6, 2019 Wasn't sure which Stuart meant. They're essentially the same thing underneath... with throttle it goes forwards, with none it comes down. Edited By Nigel R on 06/05/2019 22:54:57 Quote Link to comment Share on other sites More sharing options...

Put it on as a switchable mix engage the mix at least 3 mistakes high and have a helper on hand to switch out the mix if you are engaged.

Stuart Quinn-Harvie 1 Posted May 7, 2019 Author Share Posted May 7, 2019 ELEVATOR!! Thank you . I definitely didn't mean the Harrier - I know what one of those is Thanks Nigel. Cheap battered but flyable foamy 3d model in hand, waiting for Wednesday ( we can only fly Wed, Fri and Sun at our site. ) Yes it does look a lot of fun to learn. I wonder if it's a bit like learning to snowboard after learning to ski? ( They look the same but in many cases you have to do exactly the opposite to get the same result. This means you eat a lot of snow, and thus in this case, bend a lot of foam. Or need lots of new trousers) Quote Link to comment Share on other sites More sharing options...
Stuart Quinn-Harvie 1 Posted May 7, 2019 Author Share Posted May 7, 2019 Thanks John, I just looked it up and it seems it can be done with just elevators and throttle (my memory is probably playing tricks on me ) Quote Link to comment Share on other sites More sharing options...

Nigel R Posted May 7, 2019 Share Posted May 7, 2019 Might well be. Lots of these maneuvers have more than one name (and often fairly silly names at that) Quote Link to comment Share on other sites More sharing options...
