DL50 run-in

Die wind was maar bietjie woes die laaste paar weke, so ek dink almal se "vliegvingers" is maar redelik verroes. Intussin het ek maar die kans van 'n verlate vliegveld gebruik om gou die DL-50 se 2 ure "ground run-in" te probeer doen. Ek hou veiligeid as nommer een, dus is die airie aan die towbar vasgemaak. Ek is glad nie te vinde daarvoor dat 'n airie my bespring en my vingers probeer afbyt nie. Laat my bietjie weet wat doen julle almal, dis boring hier rond deesdae!

TRMC Open Day

Saturday the 23rd August TRMC hosted their "Open Day". It was a very successful and enjoyable event, and the weather was perfect. The wind did pick up towards the afternoon, but everybody was having too much fun to notice. There was two unfortunate incidents, but considering that there was rarely a minute without a plane in the air, and the wind WAS a bit chaotic the afternoon, the incidents was not very serious, as both planes are repairable.

Quite a few visitors was willing to grab the sticks and give piloting a go, and everybody left with smiles on their faces.

Parts of the pit lane:

Marius has a little stall where he showed visitors the magic of building your own planes, none of this ARF stuff for him,

and Marius has the skill to build absolutely beautiful planes.

Edge 540

Ek is jammer om te rapporteer dat dit 'n fatale naweek vir Werner se Edge 540 was. Die radio (Spektrum DX9) het is failsafe ingegaan, en die vliegtuig het toe ook ingegaan. Ons dink dit was steurings van die ignition. Die "range check" was suksesvol, en die eerste vlug was daar geen probleme nie. Ek was met my DX7 ook besig om te vlieg toe die gebeur het, en het geen probleem gehad nie. -- from hyper7pro - (?) -- from hyper7pro - (?) -- from hyper7pro - (?) Jammer Werner. Maar soos jy se, dit gebeur een of ander tyd met alle model vlieeniers.

Runway herstel

Ons het Saterdag 'n heel suksesvolle dag van "runway rejuvination" gehad. Die groot krake is herstel, en die hele oppervlak van die teer is weer geseel. Daar is nog 2 dromme teer oor (ons het net 2 gebruik vir die hele proses) so ons kan oor 'n maand of twee weer 'n lagie oorsit.

Hier is 'n paar fotos van Gert af:

Gliders Competitions Part 3

So what is all this F3B, F3J, F3F, F3K, Postals, HTL (Highveld Thermal League) stuff the glider pilots talk about. If you always thought it was boring to chase the one thermal after the other, then this is for you. There is various competitions in our country and internationally. The FIA have a few official classes for gliders. This is the F3B, F3J, F3F and lately F3K competitions. Each have its own rules of which I will not discuss the finer detail but rather give you and idea of the intention of the competition. You can earn your national colours by competing in these competitions at the world cup events. Let's start at the beginning where most glider competitors take part in, the Postals. This is a competition which you can fly at your local club and submit the scores to the national coordinator. You have to complete 5 flights of 6 minutes each and do a landing close to a spot. The basis of all the duration competitions is a point for each second up to the max time, starting with the release from the winch to coming to rest on landing. For every second after max time you will lose a point. So you have to land on the max time of 6 minutes exactly to earn maximum points. For each meter from the spot up to 15 meters you will lose 5 points from the total of 100 landing points. The postals scores can be entered for 2m, RES or Open classes. This competition is flown 4 times per year during February, May, August and November. The best three scores is your total for the year. In Gauteng a thermal league of 7 events are held every year. The events is rotated between the different clubs. The rules differ from event to event, but is mostly 10 minute max competitions with man on man rounds. You normally have only 12 minutes working time per slot. Your score are normalised against the best scores of the slot you fly in. Three or 4 man teams enter the event. The different classes which is scored are 2m, RES and Open. This competition is the breeding ground for aspiring SA team members. F3J is a thermal duration competition where only hand towing is allowed in stead of winches. 2 men will pull a glider with a pulley which produce massive launch heights in a short duration. The max time is 10 minutes, you only have 10 minutes working time. The time on the tow line is lost and therefore very short launches are done. F3B consists of 3 tasks. The duration task is a 10 minute max with landing. The speed task is flown with 2 sights 150m apart. The model have to do 4 length of this distance and the time is taken. The record is in the area of 14 seconds set by Darryl Perkins in South Africa. The distance task is flown with the same sights but the number of lengths flown are counted. This is the formula 1 of gliding competitions. F3F is a speed competition done on the slope and is similar than the F3B speed task. F3K is for handlaunch gliders and have many different tasks which can be flown depending on the organisers. MGA (Model Gliding Association) send every alternative year a team to the world cup for F3B and F3J. In order to qualify you have to take part in the official trial events. MGA also stage the nationals each year, where many of the different classes are competed for the SA champion. Well there you have it in a nutshell. I will be taking part in some of the competitions this year and you are welcome to join me (Assistance as timer or helper is also welcome). Cheers Gert

Hobby shops with specialised equipment

I had a hobby shop run the other day and would recommend the following for electrical and small parts and support.

1. Dion Liebenberg in Benoni (Sarel CIlliers 105, Reinfield, 0825701053. He is the SA Graupner agent (Look at www.graupner.com) and can help with many small parts like clevis, special horns, carbon push rods, etc. (German) and electric setups.

2. Mad Models (www.madmodels.co.za) (Jonathan) the best hobby shop I know of for electric models but also have many other parts and materials for building etc. From the Pomona offramp close to Kemptonpark.

3. Radio Control Repair Centre (Dave Armatage) for any custom battery packs, JR equipment and some small parts like servo plugs and wire. Garsfontein, Pta.

4. In Cape Town the only shop I will recommend is the Hobby Warehouse who is a true hobby shop. Sad to say Clowns is not what it was.

Most of the other shops are toyshops nowadays, but if you know your prices you may find a bargain.

Cheers Gert

Choosing a model Glider (Part 2)

The normal hobby shop does not have experience in advising you on gliders or stock models that can be used successful for gliding competitions. There are how ever a few knowledgeable shops and fellow glider pilots who can assist. The trusty old Gentle Lady has been used by many to learn the basics of RC aero modelling. I have seen a few available as ARF kits. Another model is the Spirit which comes in 2m RES (Rudder Elevator Spoiler) or aileron versions. Another alternative is to scratch build a model from plans. There is many plans available for sale from RCM, Traplet, etc. or freeware on the internet. The construction methods can vary from balsa and film covered models, foam and veneer to composite materials (consult a glider pilot before choosing a plan). A combination of these construction methods is normally used to achieve the best results nowadays. There are some gliders available from the local cottage industry which are built by fellow glider pilots or building groups. The Thotsi is one such example of a composite 2m glider (Foam /fibre glass wings and Fibreglass fuz) which takes most of the local competition places. Some kits are available from over seas which are worth exploring. (try ArtHobby.com)

There are many classes of gliders each with its own purpose or flying conditions. On the thermal side you will find the small 1m to 1.5m wingspan models which is launched by hand (Discuss side arm or javelin style). The larger 2m span models would be a wise choice to start with. These models can be launched by bungee or winch. The construction of the model should be carefully designed for the method of launching. In South Africa we have the RES/100 class which allow you to use larger wingspan models. These models can be constructed relatively inexpensive and can compete on a fair basis with the open class models. To be able to fly well in all conditions (wind or calm) you may have to chose a model which has a better wing section. This is not always possible with built-up models (balsa wing ribs). This is how model glides have developed from the 70’s where mostly built-up models were available up to today where the most competitive model is made of composite materials which have been moulded. The composite models are mostly imported. There is a few local designs available like the Eish!, Shongololo, Makulu and Inkwasi which all fly very well and is about half the price of the imported models. Open class gliders with full house control can be scratch built from plans as I and many others have done (even up to World Cup standard pilots do this). These models is just as competitive if built correctly and cost a fraction of the imported models, but come at a price on time.

Depending on your proficiency and available budget you will be able to find a model which suits you best. Ask for help if you are interested to take the step.
