Re: VTOL Group Build?
I'm in. Of course, rockets take off vertically too and if they land at all that's usually vertical too

Wherever there's danger, wherever there's trouble, wherever there's important work to be done....I'll be somewhere else building a model!

Re: VTOL Group Build?
I'll keep in!, might try something other than a Harrier though!!.
Hoping to return to modelling sometime this year!!

If you can walk away from a landing, it's a good landing. If you use the airplane the next day, it's an outstanding landing

Re: VTOL Group Build?
Well then, we could include autogiros capable of being jump-started ...

Haha well yes they do!
Could we count rockets?
I think we need to change the name again to the "Up and Down GB" haha!

Re: VTOL Group Build?
Not many rockets I know of do a VL. The SpaceX Falcon does. Does the Jeff Bezos one?
Not sure about autogyros. Aren't they more STOL?

Re: VTOL Group Build?
I thought rockets all do basically a controlled crash with a id if parachutes?

Yep.....
But it's still a vertical landing

Autogyros are STOL and some of them not even that. They need the forward motion provided by [usually] a pusher prop or jet to get the main rotor turning to provide lift. Queens University used to have some they used at Newtownards Airport. Most of them took longer to take off and get to 50 feet than the Cessna 172 types took to get to 100 feet.dwomby wrote:...Not sure about autogyros. Aren't they more STOL?...

Its not just how good your painting is, its how good the touch-ups are too.

Re: VTOL Group Build?
No, some autogiros ( two that I am aware of are the Ciera and Kellet ) have secondary flight controls -- a rotor transmission clutch (aka pre-rotator) which, when engaged, starts the rotor spinning before takeoff, and a collective to reduce blade pitch beforehand. The trick, and it is a trick, is to overdrive the rotor and basically pop it off off the ground, disengage the clutch, and let the engine pull it forward, back in normal autogiro mode.fredk wrote:jRatz wrote:Well then, we could include autogiros capable of being jump-started ...Autogyros are STOL and some of them not even that.

Here is an old film on youtube showing a Ciera: https://www.youtube.com/watch?v=ly261Dt1Of8;
There are a few other, new autogiros, that do this also - google "autogiro jump takeoff"
And here, from my museum, is a still sequence showing Dave Driscoll jumping a Kellet XO-60

Re: VTOL Group Build?
Then strictly its not an AUTO-Gyro
The very name indicates that the rotor is self turning and not powered.

Re: VTOL Group Build?
Fred, such a machine would still fly unpowered, the powered rotor is just meant to shorten the take off run.

Re: VTOL Group Build?
For me, with the other GBs running in January - February - early March I'd prefer it later; Mid-March into April
But I shall probably just try to fit it in when ever it is

Re: VTOL Group Build?
Unsure.
It depends on my progress with an off-line conversion project.
