Helicopters . An unbiased view about the evil things,
Getting a steady hover, week 3

 The difference in stability between a helicopter and a fixed-wing aircraft is often compared to a child's swing which is hung by steel rods. If it is pushed from its normal motionless position and then left alone, the swing will sooner or later of its own accord stop exactly where it was originally. The stability of a fixed wing is similar. A helicopter, however, is like the same swing, only this time balanced upside down. If disturbed it will fall away from where it was with ever increasing speed and will never attempt to return to its original position.
To me it seems worse than that, add in what one flight simulator calls cyclic instability, the heli does not want to keep still.
Due to poor weather and the wind I had not flown my little Shogun until Saturday's evening session, this started badly with some very wobbly hovering and lots of advice not to move the sticks so much. I made some improvement, enough for the heli crowd to recommend removing the training undercarriage, this will stay for a while. I can now hover but only tail in and needing 100% concentration.

Video of me crashing, the canopy falls off, it appears to go tail heavy and crashes into the barrier, brain failure stopped putting down in or reducing the throttle  please don't laugh

Slope flying

Friday 23rd – Selsley 

Bang on West, no turbulence, massive lift, 22 mph gusting 30+ Best lift ever I can remember for this slope, severely chilly though! Blue skies and sun too! 

Andy with AliaJ – he launched, Christine flew (my hasn’t she come on in the last few months, needs to give Andy a few tips though?) 2/3rds ballast made the AJ ‘come alive’. Constant motion and great penetration, the grey clouds in the blue sky gave a few ’where the hell is it’ problems. 

Guy with his ancient Phase 6 Pro and trusty MiraJ. As we left, I really thought I’d missed the opportunity to fly it with full ballast on board. One of those rare opportunities, in awesome lift. 

Graham with his new Phase 4. Did the book in the aerobat department, as he does. No problems penetrating at all. 

A nameless flyer from Wooton under Edge, let’s call him ‘channel 73’. He flew an ‘own build’ Sitar Special a la Solent Sailplanes of 20 years ago. Bagged wings, Kevlar hinges, home spun epoxy fuselage. Flew great and was constructed to outlast the SS original by about 19 years. 

Where was Phil with his Nyx? It would have loved it!

Good lift - Guy

Saturday PM : Light lift at Frocester when the wind was truly SW the lift was quite good but it was drifting to S at times then it became a 'bit iffy', Tony, Christine and Andy and three other flyers. Good sunshine all afternoon. One of the other flyers landed out across the road in the middle of the farmers field....................

Friday PM : Very strong lift at Selsley West, the wind was measured at 32 MPH. This strong lift was enjoyed by Guy, flying his Miraj and Phase 6, Graham with his Phase 2 ?, Christine and Andy were flying Andy's Alliaj with nearly 2 LBS of lead ballast, it was going well. There was one other flyer, unfortunately I did not get his name, flying a Sitar ?...................

Thursday PM : Wind was on Selsley West, just.................In the normal way the lift was a bit intermittent. The only notable event worth reporting was that Christine did her first 'solo flight', a feat never to be repeated. Guy flew his Miraj, Andy flew Christine's Prodij................ we cried enough at about 3:15, Graham went to Frocester and enjoyed a very good late afternoon session.

Monday PM : Wind direction was SSW, Christine and Andy tried Frocester, the conditions were not suitable for flying anything but a foamy, Christine had lots of practice landing ! !


Sorry we missed the meeting Wednesday, I was not feeling well, just about OK now though.

Cheers for now, see you on the slope.

Andy Dunan

A good breeze at Haresfield, flying started in the bowl near the car park and then moved to the main slope
