Finding thermals is usually an art - although sometimes a big one finds you! Generally the model will just start to climb more rapidly, often there is turbulence associated with the thermal too so the model is bounced about. I will scan some of the pages from my Thermal Soaring book on the subject for you. Being a biplane the Tom Tit is a bit "draggy" and would need quite strong lift to soar, but your little Redwing should be able to climb very well in even light lift.

The brake is used to make sure on a soaring model that the prop folds when you cut the throttle, no brake set in the ESC and it just windmills causing drag. I don't have a folding prop on the little Tarquin, but even the little 5 x 3 windmilling acts like an air brake which spoils the glide, which is why I want to brake it, less drag with it stationary.
