Thermal Circle Text - Thermal Circle 04

Written by Hayden Daley - 12 September, 2007.
In this edition of the soaring circle we will take a look at composite model manafacturers as well as some information on the new world soaring class for scale sailplanes f3i. To me this extremely exciting as we now have the basis for a new style of contest that will hopefully allow for static judging and soaring flying. Personally I hope this new class will encourage manafacturer to produce radios with more channels and options for scale sailplanes. Personally alot of my scale models run twelve channels as is, and I need two more for water ballast and Variometer control , taking the channel count to 14. Im sure the jet modellers are having the same problems. The need to run more channels is really dictated by the sub trims and other functions that allow the set up of the model, and Y leads dont allow for this programming facility. The new Futaba 14 channel radio will sell well as many pilots will buy these set for the extra two channels available. I think that the next tecnological step is a radio of 16 channels and the channels being of equal importance need to be taken into consideration by the development teams of the major manafacturers, as models get larger and more sophisticated. Now onto composite model manafacturers.

Composite Model Manafacturers

The companys listed are specialist manafacuturers or distributors of composite competition sailplanes as used in the multi-task soaring competitions or f3j thermal events.

Competition sailplane are some of the best flying models you can buy. They are strong,efficient, exciting to fly and because of the computer cut molds are very accurately made with no warps or other inacuracies in the finished product. Molded models have a very high strength to weight ratio and are very durable the only down side is that they are difficult to repair. Remeber when ordering, to insure all shipments, no matter how small the order is and also ask for the freight tracking number when paying. Most of these companies will take credit cards over the phone, however occasionly you will find that you may have to transfer funds into acounts in foreign countries. This can be done at pretty much any bank. Also remember to check and confirm what lay ups are available and other different options when ordering your model. Also when ordering take into account the Australian dollar, being patient can save a large amount when buying new composite models.

New world soaring class f3i

There is a new class of contest rules that are currently being voted on by the FAI,f3i. F3i information is hard to find at the moment but I believe the FAI is looking at multi task style of event similar to the f3b rules. Personally I believe that f3i should include static judging, with judgings for scratch built models and models built from a semi kit and have a soaring element with a vario and non vario class. The event would entail scale judging and an equal launch height for say a 15 minute flight with a non vario model and say thirty minutes for a model with a vario, with one hour working time to completete the flight. Acheiving the required flight times would result in 1000points and all pilots acheivng the times will receive a maximum score, with no landing bonuses. I think that f3i with these rules would be an interesting event and allow for the construction element that makes scale soaring such a challenge.

The soaring circle now has a contact point, an email address so feel free to send any suggestions, questions or topics that you would like to see covered in this magazine to, soaring@newlitho.com.au. Thats it for this issue, happy soaring.Hayden Daley
