New Gyroplane has arrived! Pics inside.

A gyro thread without this picture. For shame.
OP, gyros used to have an awful rep for falling out of the sky, have things improved with them, or they still a bit 'twitchy'?
There's recently been loads of work done to improve the safety of Gyro's, not that they were dangerous before if you flew them within a certain envelope!OP, gyros used to have an awful rep for falling out of the sky, have things improved with them, or they still a bit 'twitchy'?
The one thing they don't like is airflow going through the top of the rotor, (zero negative "G" manoeuvres) it tends to stop it rotating which is not good
You'll notice all of the modern Gyrocopters have bigger tailplane structures held further back from the rotor head mast. This, I am led to believe, creates
much more pitch stability thus making dangerous severe forward pitch manoeuvres a lot harder, if indeed not impossible to achieve.
I'm sure an expert will be along soon to put my waffle straight
It's the same as most aircraft, there's a safe operating envelope and a dangerous operating envelope. Modern high powered flexwings can be dangerous in a very steep climbs.
A 100bhp Rotax 912 will create silly climb angles in this type of aircraft. You have very little kinetic energy to play with in the airframe should power be lost. You have to be very quick to pull the bar
in and kill the climb angle before loosing airspeed and stalling. Unfortunately, in these circumstances, it is possible for the aircraft to "whip stall" which can lead to a "tumble" (continuous nose over tail plummet)
from which there is little chance of recovery. http://www.youtube.com/watch?v=U_vbrMUCuZE&pla...
It's no different to a car, drive it out of its, or indeed your limits, and it'll hurt you...

It was a negative G manouever that killed an autogyro (my preferred term) pilot at the 1970 Farnborough Air Show.
I believe that this is made worse in (generally older) designs where the thrust line is above the CG - as power is applied to recover, the gyro bunts over and cannot regain normal flight.There is no way on god's earth that will fly. Surely there must be a big bit of string somewhere tethered to the sky 
What a great bit of kit. That said you wouldn't get me in one for love nor money
Have fun and please post a video of it in action if you ever get the chance ( to prove me wrong).

Lovely Gyro Ben.
My knowledge of them extends to a fair few hours visiting a certain pioneer of Gyros and then watching him have a play in his back garden.
Great man to listen to, got some fantastic stories.
I've got a video somewhere if anybody is interested, will try to dig it out.

But the breakfast there is rather nice and the avgas is cheap!
Breakfast is nice there but we run on V max not avgas Got told after I pumped 53 litres into jerry cans last night that they could only sell up to 10 litres of 97octane in cans... I just said I needed 80 litres and I cant exactly pour it back!

t, it's max can size, not the max they can sell according to the notices on the pumpsOnly going off what their (very) broken English said, they still sold it to me. They were hardly going to refuse £115 at 8:00pm on a Saturday night, I was the only person there! and probably one of 5 who would turn up all night, they are a little remote...and very expensive! (£1.40 per litre for diesel and £1.41 for 97 octane petrol!!)
ETA - They wouldn't let me pump at all until I held the cans up for them to see, if they couldn't tell that they were jerry cans and would hold 20L each then they are rather more stupid than they looked.
