Russ "Russel's up" aero tow interest at Karkloof

Some pictures taken at the Karkloof Country Club on 13 November.  The main focus was on aerotowing large scale model gliders. The weather was less than ideal with 10/10 low cloud.  Fortunately there was no rain. The event was well attended and everyone had fun.

Cheers for now.

COMMENTS

Windguru was emphatic that there would be no flying all weekend because of drizzle, but fortunately for us it was wrong, and we had cold but flyable weather even with some blue skies, until 2 pm. Thirteen entrants, many from Durban, were so keen on entering that they braved the grotty day they saw from their homes! Our entries are now growing bigger, and I think we will start future rounds at 8 instead of 9 to accommodate this.

The new A12 pattern for Masters was a big hit. Everyone liked the gracefulness of this, and its level of difficulty. The F3A pilots also approved of the new P13, and Jason liked the chance to fly the choice of P or F for round 2. There were no entrants in Advanced. Time will tell if people want to move up to this from Sportsman, or perhaps they may prefer to jump up two steps to the Masters class, which is well supported.

In Novice we were pleased to have Angus McInnes do a good job, and get 62%.

Sportsman was led by Lynton Milner, who is not yet quite used to flying the glo powered "Venus" he acquired from Ian Morris, but still came top. Second place was a welcome new face to the pattern scene, Stan Hausmann from the Umhlanga club, flying his large scale "Beast", after only a few practice flights of our pattern. Dave Greer surprised us with his neat flying of his small electric "Diamante".

In Advanced Mark Savage flew a new "Wind S" 2m into an excellent 66%. The others are still getting up to speed on the new pattern. Alex borrowed my plane for the last round, and flew it without a test flight.

In F3A Jason astonished us by not only getting in a good P pattern, but had managed to learn the very difficult F pretty thoroughly as well in only four weeks! This bodes well for his serious push to try for team selection for the 2013 World Champs. Jason and Arthur have both got new 2m "Wind S" planes, which are not yet trimmed out to compete, making this design the plane of choice it seems.

Thank you very sincerely judges for your long travel to get to the event, and thank you Howick MFC for giving us a bowling green smooth grass runway, and a very welcome braai.

Nothing better than a sun downer flight at Zigginanda!

Sharkie text developed from "The" of the "The Sharks" - note the NvS sticker. 

After sampling the Minivec first flight, it was realised that other sloper non mouldie grand plans were out the window, including an updated Ghostbuster for the Summer evening light fly sessions. The Luke and Michel Flight Pro "Flying Fish" offered all the wing area of the Ghostbuster, along with the simple uncluttered fuselage and tail end, so it was a slam dunk decision.

The weather finally permitted a mid week afternoon rush to the Inanda slope in idylic weather, yesterday. The 4:05pm Umhlanga departure through virtually no traffic hindrance (surprisingly) meant arrival at the slope 40 minutes later.

It had been decided to stay with the Andy Ellison throw options and CG at 91mm from LE. There was instant realisation on launch that is was fine for the Ellison/Leusch/Conradt nimble fingers but yours truly would be more happy closer to Luke's recommended 85mm from LE. A dive test revealed a dead straight dive that would have finished in the dam so Andy spot on but not my preference, which is for the gentle climb out.

Andy's max aileron throw (12mm up 10mm) was perfect all round, with the slight differential kicking the stall turn over nicely. Aileron low rate was wishy-washy, mode 2 pilots only need apply there ;-). Elevator on the other hand was much nicer on the low rate (5mm each way), given the critical CG setting.

The plane was sweet to fly in the conditions, obviously the slight dihedral etc precluded Minivec rachet aerobatics (not my intention) but it was still damn good and will benefit even more with a 150 to 200 grams permanent ballast on the future CG. With the light inertia, one had to pull harder over the top of the large loops or the beastie would happily float away to the sunset, inverted.  

Those who have flown Zigginanda in light conditions will know just how uncannily quiet it is so it was quite shock to hear a wap, wap, wap and a huge whoosh as a predator bird zoomed past my left shoulder, intent on having Sharkie for dinner. Luckily the predator lost interest after trying to follow though a couple of huge loops, although he gave looping a really good try.

Landing was a doddle on the Andy recommended 11mm spoileron reflex with 2mm down elevator compensation. I had gone with short servo arms for maximum resolution but would opt for longer arms, just short of the cover tops, to keep the push rod parallel with the wing surface and minimise any "going around the corner" binding on full aileron and full spoileron combined. I had previously set up the the braking only on low aileron rates so no big deal there but worth noting for those interested.

I have not one single criticism of the model - the plane was a pleasure to assemble (what little there was) and everything fitted perfectly. Having saved by using some cheapy Turnigy metal gear sub micros from Flight Pro on ailerons, I lashed out extra on a pricey HS65 MG for pitch and that, coupled with the (thanks Russ) Craig Baker trick of super glue and micro balloons on the elevator horn hole released by the oiled push rod, meant zero slop, magic! The only change I made was to lay the servo on its side on a ply platform, which meant the piano wire snake ran down and was epoxied to the side of the fuselage and left ALL the room for the ballast area. A useful change as the supplied servo tray places the servo in the center, rather than off to one side, which other reviewers have mentioned as well.

The maiden flight quickly gobbled up a half hour and I landed at 5:25pm, conscious of getting home in day light. Again the traffic waters amazingly parted and I was back in Umhlanga at 6:05pm - a useful two hour round trip but not one I would want to repeat too often so next stop Springfield in the mid week NE ;-)

An excellent buy at the asking price from Flight Pro and I am sorted for the Summer! 

FPV Quadcopter flying

Here's my first recorded videos of the weekend's FPV quadcopter flying. For those who don't know, FPV stands for First Person View, where I fly from a live video feed sent from the quadcopter, which I then view through video goggles on the ground. It's as if I'm sitting inside the aircraft.

The first video was at Umhlanga Radio Flyers Club, and the second was north of Durban at Beachbums Backpackers. The wind was blowing strong this weekend so the video is a bit bumpy, but it was fun!

Famous

An American friend of mine sent me this page from "Quiet & Electric Flight" Magazine.... I got a bit of a shock! Finding myself in the famous RC magazine. Anyway - pretty cool, just sad that this aerie is in the big aerie graveyard in the sky...

N v S results hot off the press

North v South CONTEST RESULTS (Top 2 results gave the trophy to Kzn)

Aerobatics

1. 78.90% Michel Leusch (Minivec)

2. 71.92% Russ Conradt (Shongiloma)

3. 71.68% Christo le Roux (Aldij)

4. 71.45% Dave Greer (Minivec)

5. 69.17% Kev Farr (Vector 3)

6. 64.56% Jeff Steffen (Aldij)

7. 61.95% Simon Nelson (OD Weaver)

8. 57.11% Ryan Nelson (OD Weaver)

Second to fourth separated by less than 0.5%!

4 ZAGI BY 4 LAP RACING:

1. Michel Leusch (Jeff Steffen's Zagi)

2. Luke Johnstone

The competitor count is a reflection of the hard core folk who hung in to the bitter end on Sunday, rather than the surprisingly large number of folk who attended over the three days (14 initial contest entries). Friday was bliss SW practice time at Inanda, Saturday wind strong but lift light and Sunday at Switchblade downright Berg wind challenging! Simon's bright idea of the Zagi x 4 racing generated a dozen or so racers who had a blast, a useful idea for keeping things ticking along during "non aerobatic" air.

Reports and lotsa pics will follow on the Toss and this blog, keep a watch out. Special mention must be made of Russ's huge time, money and stress input to the event (not to forget Mandy and Kelly Conradt's magic hospitality), along with Dennis Bird for CD support for Sunday - as well as Luke and Dean for judging. Ever cheerful Adi Critten and Rudi Smook made it all that bit more special. Our appreciation to Tosser's Jeff Steffen, Christo le Roux and Kev Farr for flying up from the Cape for the three days - they have promised a bigger mob for next year, to wrest the trophy back from the Sharkies!

North v South slope challenge info

Here is the crib schedule of manoeuvres off the scoring program for the aerobatics part of the slope challenge weekend. A nice range of "non scary-complex" manoeuvres suited to Kzn slope conditions.

Start times are never cast in stone for slope events but Russ's Saturday intention is to meet at the Sasol at 9am for a 10am arrival at the slope. This may vary so please keep in touch with Russ on 0828227887.

For those not used to the route, meet with the convoy at the Sasol garage at the Kwamashu turnoff from the N2/North Coast intersection or follow these excellent Google directions, courtesy of Johan Moelich:

Sneak peek ahead of North v South slope challenge

The local lads are looking forward to Russ's next week (17/18 September) slope aerobatic challenge against the three Two Oceans Slope Soaring (TOSS) lads coming up from the Cape. A recent brief window of opportunity saw a couple Minivec slope aircraft arrive in Durban and the race now on to have these ready for the event. Mark got to experience the maiden flight in excellent slope conditions at Ziggy-nanda this afternoon. This amazing aircraft was not only a dream to assemble but also completely blew us away on its maiden flight. A vice-less pussycat for relative novice Mark but on rails for aerobatic work, with an energy retention that was stunning..... Mark was quickly trying things he had never experimented with on the slope before. He had followed the instructions implicitly and there was not a single peep of trim needed to any single control surface! Everything else we own slope wise is now instantly redundant - kudos to James the Hambone for the stunning design and the China factory for building it so right.

Yours truly has always been negative about slope aircraft with fully symmetrical sections ever working on the Kzn slopes, well that theory was well and truly proved dead wrong, the effortless way that the craft cuts through the air shows just how clean and accurate is the only way forward, remarkable.....

A visit to Umhlanga club for e flight

Activity at the college had Johan and Dave pay a visit to the Umlanga club field near Hazelmere dam, instead, where a pleasant morning's flying was had with George and Stan, which were quite taken with Johan's quad copter now being flown remotely from the onboard camera by Johan through the glasses. The picture from the teeny camera was remarkable and Johan's confidence grew with each flight. Also impressive for us was Stan's large scale Pilatus that flew immaculately and had such presence in the sky, it could be mistaken for the real thing! Complete with retractable undercarriage and flaps.

KZN Pattern Round Results

July 24th 2011. A League round (which counts towards qualifying for the Masters event)

Held at DMAC Gromor field

Judges

Des Cooper, Fred Wilkinson, Bruce Bell, Johan Britz, Mike Cox, Colin Addis. Thank you for your help.

The results are tabled in this pdf file above. This scoring work was very well done by Fred Wilkinson. Fred is also interested in tabulating the results per judge, to send in to Ivan Olivier, to have our judges nationally graded.

This will be very useful to us, as when we have a provincial event, which we may well do in mid 2012, we will have qualified judges who live in our province. This reduces the costs and hassle of an event drastically. Also, our judges can be graded and promoted with time, and can become National judges and perhaps even International judges. Note that at the 2011 World Aerobatic Champs S.Africa have Bob Skinner as one of the three jury members, and Christo Rust as one of the 18 judges. No other country has more than this.

It is interesting to see that Fred has evolved into our "stricter" judge. We all know that it doesn't matter for one contest whether a judge scores high or low, as long as he is consistent and places the flyers in the correct order. Fred is quite correctly grading by the stricter judging as done nationally in S.A., particularly for the higher classes. I have just seen the first round scores at the 2011 World Champs, and note that Christophe Paysant LeRoux has got only 79%, and all three of our S A guys got 63%. So that means that even our national standards are too generous for international events.

Comments

A fantastic entry of 16 pilots hits a new record! With the pilots getting into the air in slick succession we managed three rounds, a braai, and finished by 3:00pm. Pilots needing to get away early were fitted in easily. We were lucky with the weather, as the day after the event was gales, floods and snow. There was some wind early on, but the F3A and Masters pilots took the brunt of this.

A lovely venu, and a sociable braai - thanks to DMAC and Clive Gager in particular.

Novice

We were delighted to have Eike have his first very competent try at pattern, quite appropriately with a Matt designed Saphir from 20 years ago. Clive has flown once before, and used his large scale petrol plane, to get the top score 0,6 percent ahead.

Sportsman

Speedy van Niekerk managed to get away long enough from fixing helicopters for the Durban Port, to get back on his Nats form, and break 60%, as did Lynton. Colin and Dave were just behind, with very good flying from Dave Greer with his .25 size electric Diamante doing his first try at this class. It had astonishing vertical performance, but I think he psyched himself out of doing a proper stall turn by declaring in advance that it wouldn't do one!

Advanced

Johan de Lange flew with us for the last we will see of him before going to Saudi for a two year stint. His 2m Osmose was flown excellently. Arthur was less than a percent behind, and when he can get the distance flown correct, he will be as good or better. Clive, Alex and Ian all got over 60%

Masters

John was the only entry, with his 110 size electric Siebart WindS, and did well.

F3A

It is such a pleasure to have Jason to compete against in this class. He got a 68%, and I flew much better without my Nats nerves. We were both flying 2m electric planes.

Distance

None of our 16 flyers flew too far out. A small number of the pilots, such as Johan, flew the right distance out, and it is no coincidence that his score was very high. A 2 metre plane should be flown 140 to 170 metres away from the pilot, and a smaller plane proportionally less far out, so that it looks about the same. Nearly everybody else flew MUCH closer in than that. I know that when a plane gets very far out it is not so easy to see if the wings are level in flight. But just try and get used to seeing it further out. You may be surprised that you can let it go for a bit with level wings, even if you cannot see it as well as you would like. Certainly on a windy day you are going to find it totally impossible to exit from one turnaround manoeuvre, fly straight and level for a short while, do three rolls downwind, then another little straight and level, then do an end box manoeuvre if you are only 100 metres away. Give it some practice and try.

Regards

Neil Allen

Experimenting with movies from recent posts

Rather than using up blog space, I am trying linking to these slightly bigger than normal movies at 3 and 5 megs respectively. It would otherwise make the movie very small if staying under 2 meg.

The first is Luke's foamy pusher at the recent Ziggynanda slope fly in, worth winding up the sound ;-)

e Sportsman aerobats at Kzn Pattern monthly

Whew, quite a weekend of e-flying, starting with Saturday early morning with Johan and Paul at Umhlanga, then off to Gromor for some flight orientation for the pattern monthly at same on Sunday. Paul is enjoying his Bug-e electrified R75 foamy and coming along nicely with it, shown at max concentration in the first pic.

Did not start well for yours truly as it was evident that the Dualsky driven Diamante had lost some of it's awesome grunt, almost like dropping from four cells to three but could be any of the three components. A quick call to the LHS revealed no spare battery, so it was a simple case of pressing on as is or risk the title of "chicken"..... ;-)

Progress with the Diamante had been spotty as your truly just could not resolve tearing out the undercarriage with regular monotony, which had put a damper on regular practice. It look some well glued in doublers by Russ, coupled with four mini self tapping screws and a lightweight "soft" carbon undercarriage to finally resolve this a week or two ago. An otherwise excellent sport E craft.

Arrived at Gromor to find Robbie Rowe and his mate Rob about to pack up after some magic flying in the glorious weather. Also blast from the past Gys Wygers, in the pic with Big Stik plane and Rob. Also up there were Ian Morris and Speedy to do some practice, which was a boon as it gave a chance to correct any bad habits from our "blind leading the blind" practice at Umhlanga.

Both Ian and Speedy were most helpful and also helped out with some calling, after a couple of runs. It was clear that I was unused to being instructed by a caller, despite my best efforts to adapt. The other thing was that practice had been on the basis of "flowing" the sequence for best slope style momentum, after all the objective had been to brush up for slope aerobatics, given the iffy Kzn winds over the past couple of years.....

Speedy was armed with the Sebart 110 in the pics and a useful 4th from Nats, so I was starting to feel that maybe I had bitten off a bit too much with my parkie plane against this immaculate, well flown, plane. The weather was so magic, we only departed the field at 2:30pm!

Arrival at the field on Sunday revealed the almost blown off wind sock in the pics and lots of folk gathered around in jackets. Neil's accommodating style of hosting events was again shown in putting up the F3A boffs first in the hectic wind and leaving us Sportman folk till later, when the wind had abated.

I was very, very relieved so see that was in fact quite a cross section of "clubbie" planes and pilots in Sportsman - Gys with Big stick, Colin and Mike with Zeniths, Clive Gager with Cap, and so on. Neil was also chuffed to have a record entry of 16 pilots and a group of new judges to blood. It was also magic to meet up Bruce and Missus from the Kingsburgh club again.

Johan de Lange kindly accepted to call for me and I immediately felt at ease with his calm, non "instructing" style of calling and the first round was completed with some relief despite a hiccup on the roll and completely blowing the stall turn - something that had been anticipated. There were some useful 6's and 7's but zeros and bum scores really hurt the average, so 48% became the start average for my very first Sportsman comp. The second round was pretty more of the same and a marginal increase in average. Fred alias "FW" (not as in Fred Wittstock" ;-) was particularly sobering on the scoring and hammered my wandering out the left edge of the box.

Johan put in some good flights in Advanced and had to leave early, so Arthur Eggar stepped in to call the last round. It is ironic that the only time he bullied me in the whole flight was for the stall turn and it was my first successful stall turn. The stern "right rudder now!" was not to be argued with and worked a treat! Man, it was nice to tot up some scores with no zeros lurking on the sheet and rewarding to have a top judge score of about 62% and lowest of 52%, averaging out at 56%. Does not seem a lot but top dog Speedy and Sebart had managed 59% the first two rounds and only cracked over 60% in the last, so it is tough to break in to the 60's.

All the folk were most encouraging and friendly and I will definitely be back for more, Neil and his hard working team have really put together an excellent formula for what previously seemed an elitist discipline. I would encourage all newbies to add this to their learning curve and it was interesting see Dudley watching most of the event and will no doubt be giving it a whirl at some stage.

Apologies for the selfish personal blow by blow report , rather than the event itself, but it was very much a big first step for this glider guider in disguise....
