Ben,
You have got a point since the risk of extra weight and the complexity of assembly may counteract the goal, especially with very small models.
And since most R/C radios today have dual-rate facility, the R/C pilot may choose larger throws angles during slower flights and smaller ones when flying fast.
Anyway, it may be an interesting area to explore for those who like to experiment…

Flicka5,
"Flicka" means "girl" in Swedish, are you a "Flicka" from Sweden?!
As for your "tack" I should say "välkommen"!

Vänliga hälsningar,
