Who would be ready to share his adventures with stab sections and shape ?
40 years ago, the use of the VIT on our wakefields stopped any in-depth study on the stabilizers – for our outdoor models with fast climb, F1B, Coupes d’Hiver, P30, Open. Champions like Hofsaess or Werfl acknowledge however that they had to test 3 or 4 different stabilizers to obtain a good result… but this was only a work of “try and error”.
I am trying to understand something in this aerodynamic challenge: without timer nor VIT, how to obtain the best glide without handicapping the climb, and conversely. It is not for the competition, but just for the pleasure of knowing.
Do you have experience on the use of various stabilizers on the same contest model, glider or rubber powered? Especially with a symmetrical profile, and “flat plate”? A key would be the shift of the CG, but each detail is of importance.
If we end to some interesting result, it will be published: Free Fligth Quarterly, Thermiksense, Vol Libre, Volo Libero Italia.
