Sheffield PSS Fly-In - 22nd May 2005

Report by Peter Hitchborne

Steve Griffiths' FJ-4 Fury commences another strafing run at Sheffield

Having organised an event I always feel somehow responsible for the weather on the day and anxiously check the forecasts from the Met Office, the BBC and the local Peak forecasters.  The forecast had changed over the two days prior to the event and I emailed Steve Griffiths the very latest from the Peak District site which showed quite strong southerly winds and a chance of showers.  It was with some relief that I turned up at Callow Bank about 9am on Sunday morning 22nd May to find a fairly good South Westerly and decided to test out the West slope with my Banana mouldie (before Steve Griffiths arrived!)  The sky was only partially cloudy, the sun was out and there was excellent visibility.  The Chairman of the club, John Penton also turned up with a similar thought and we pronounced the event 'Open' as we were both able to find plenty of lift around the slope.

Phil Cooke was the first visitor to arrive and soon had his excellent EPP Lockheed T-33 in the air, but it was clear the conditions would be changeable during the day as he occasionally struggled for lift and took out some of the huge battery packs that he was using for ballast.

As the morning wore on the threatened showers didn't appear but the lift was intermittent as the wind seemed to shift more to the South.  Martin Middleton was easily able to fly his Lockheed U2 however, with its clean  lines and high aspect ratio wings, but others struggled in the changing conditions. 

Simon Cocker flew his much travelled and very convincing Boeing B-52 - a brave decision in the conditions - and I was very impressed with Steve Griffiths' NA Fury, beautifully finished in light grey and flown superbly (title image).  He also flew his excellent little P-51D Mustang, (right) the plan of which is soon to be available from a National magazine.

 

Mike Briggs' Hawk 200 flew well but I was very reluctant to test fly my new T-45 Goshawk from the same Conway/Griffiths/Briggs plans, resulting in much prodding and banter.  I was finally badgered into it, by the usual suspects, as Simon Cocker picked it up and walked purposefully towards the slope edge.

I hate first flights with all moving tailplanes, it seems that no amount of checking the incidence helps.  The advice I'd been given by the expert (Steve Griffiths) was 'Give it about an eighth of an inch of up elevator, keep your finger on the trim lever and hope for the best!'  This proved to be timely advice as, immediately after launch, I needed all the up trim available and a bit more besides!  Luckily the ailerons needed only a tiny amount of trim so I was able to concentrate on pitch corrections and the flight was shortened only by the lack of lift resulting in a slope side landing with no damage.  Back to the drawing board with the CofG position, requiring a lighter battery and the loss of some forward weight!

By midday the wind appeared to have shifted over to the South as the smoke from the Blue Circle cement works chimney four miles away could be seen trailing to the right of the slope and Martin Middleton tested both slopes with his resilient EPP Me-163 Komet.  This model, imported I believe from the states is striking in the air, being red with Black and white insignia and flies remarkably well considering the dumpy shaped fuselage and delta wing.  The lift was pronounced to be on the South slope and the whole caravan of models, Tx cases and haversacks full of lunch and cameras were carried the couple of hundred yards to the (much) steeper but shorter slope.

Immediately on arrival there was a question whether we had made the right choice but the lift proved to be reasonable if not brilliant.  The stars of the show were the two T-33s of Phil Cooke and Simon Cocker flying in formation, close to the slope giving everyone with a camera a whale of a time.

Model flew very well at Sheffield

 

Colin Troise of the local club test flew his unfinished Cambrian Spitfire only to find there was insufficient aileron movement.  I launched the model for him and as the flight started I was glad he had exonerated me from blame should it crash as the lack of control resulted in a wild flight as Colin fought to keep wayward model in the air in poor lift.  Eventually a smiling Colin returned to the pits after a safe landing and I was very relieved that there was no damage.

Alan Hulme suffered similar problems with his FW152 - discovering later that only one of his ailerons was working.  The south slope is somewhat unlucky for Alan, I remember catching my breath as he launched his Dewoitine on a previous visit to the slope and watching it struggle for lift, eventually landing out below.  The same fate awaited Simon Timperley of the local club who brought to the slope the smallest RC model glider I had ever seen and watched as it plummeted a couple of hundred feet to the valley bottom.  It was so tiny in fact that he had to be shepherded to its resting spot by whistles and hand movements from the top of the slope, unable himself to see the model in the deep bracken.

As the afternoon progressed rain could be seen approaching on the horizon but my prediction that it would pass us by proved to be false in the extreme as we were drowned in rain and hail at about 3:15pm.  After 20 minutes of drying out in the car and a warming coffee the skies once again cleared but a resulting very light wind signalled the end of the days PSS flying.

The next meeting at Sheffield is Sunday June 26th which being so close to midsummer should provide good weather and with any luck a strong westerly!  Being close to the longest day let's hope we fly so much we have to change batteries!  The September event will be an informal competition, to add a little spice to the day, so practice those victory rolls and Immelmans!!
