The Aurora TT is not only pitched as a low-weight high-end F3K performer but also as a resilient model for daily use. I’m not into F3K competition. So the latter is what I purchased the Aurora for. Not only will it have to take thermal lift, but also low winds at the slope. As a consequence, guiding principles for the build will be:

  1. Durability goes before saving weight
  2. Ease of use goes before leading edge performance

And, as usual, Flying Tom’s build and safety standards apply.

„Tail Feathers“ Steering Linkage

I’ve never been a patron of the string and spring steering linkages normally used with competition DLGs these days. That is because of the fiddly work to set it up and maintain it. But also, and more importantly, because of the permanent tension imposed on the structure by the high-strung steering linkage. Thus, my daily flyers usually get a conventional 0.5 mm steel rod linkage guided by 1.8 mm polystyrene tubing. Weight is about 4 grams per metre, resulting in a weight punishment of 6 to 7 grams over the string and spring type for rudder and elevator of an average DLG. However, with a risk of ending up tail-heavy if not compensated properly.

It goes without saying that Aurora came with a coil of strings and two torsion springs. For this time, as a test for long-term behaviour, I’ll try to overcome my misgivings and build it this way.
