Helicopters . An unbiased view about the evil things,
getting on with it, week 5
Last week I bought a Twister Storm 3D, this came ARTF just the blades and undercarriage to fit. The instruction gave the settings for common transmitters. The one bit that baffled me was the heading hold gyro, this would give full deflection to the tail rotor servo. I checked on the interweb and found this was correct, the gyro is trying to return the heli to its starting position, the stick input from the rudder tells the gyro the rate of yaw required.
One thing worries me, if the gyro was perfect and you had enough power for a 12 hour flight would the heli rotate 180 degrees ?
I have always imagined a piezo gyro like a wobbling jelly, if it is wobbling symmetrically
when still, rotating it will alter the the wobble to a new pattern. The
crystal in a solid state gryro vibrates and if you rotate it coriolis
alters the pattern of these vibrations and sensors detect this.
Back to the Twister , this came with all the servos and gyro fitted, a
battery , charger both mains and battery, I soon had the blades whizzing
round on the floor and getting light on the training under carriage. This is
heavy model and not for indoors so I powered down, luckily it was Saturday and I
could fly at Bentham. It hovered fine just needing a bit of right trim and made a
little less sensitive with the 80% rates and 25% expo.
Indoors at Bentham
No real progress made, just a little more confidence in the hover and a bit of sideways

Unlike many UK schools, London transport, most airports and many other major
national utilities Glos MFC was not going to stop just because of a little snow.
Ignoring warnings of major catastrophe with multiple deaths and injuries caution
was thrown to the wind.
With Paul G. announcing that the Holy Cow had a bit of a runny nose and was confined to home to avoid a foot and mouth scare members were able to make their way to Bentham and fly safe in the knowledge that the GMFC committee had considered all the health and safety issues before carrying on with life as usual. As it turn out the roads were clear and the freezing temperatures forecast did not appear.
However as expected numbers were down to twenty, with the majority again

Club meeting 18th February. We were going to watch some Aeorplane DVDs. Unfortunately I can't make the meeting with the equipment, so will postpone the DVD's till March. Instead we will have "bring what you are building" to the February 18th meeting. (Bryan)
A cross country comp is planned Sunday Feb. 22nd, beginners and the nervous will be given help
Friday good lift on Selsley, the Common was very crowded with people enjoying the snow.

There were twelve or more paragliders airborne at one time
and several, unfortunately, had no regard for the safety line agreed to keep us
Bryan: Managed to get back from Hairsfields OK. Nice breeze, just enough for the 5C Zagi. Nobody about to get a flying shot.
Also had a go on Minch with the electric. The take off runway had been conveniantly cleared for take off.
If you got Pauls email, he might be interested.
Cheers for now.
Sunday afternoon, Feb 8th,
Calm most places but at least
15mph on the small bowl. I sometimes wonder if this is the windiest spot in
Phenomenal lift for the tiny
Slipstream but the odd spot of rain quickly turned into a snow blizzard and
impossible visibility. I fled!
