From the small to the big one, you always need to increase the speed to overcome the weight.

yes, faster than small gliders, but still relatively slow... it's only 1,4kg for 4m wingspan.

ummm... the vert-stab is significantly taller than it needs to be. the stab is, therefore, making relatively more Drag.

i'm not a glider design expert, but I have the feeling that most F5j gliders have the same type of stab. I like it, can thermal very very tight spirals.

0:58 effective damn must be nice to have a massive glider, don't have to worry about visual loss in a boomer thermal it just floats damn

Hi Jacob, all my other gliders are max 1,5m, I flew them for years and was and I am still very happy with them. Both have pro's and contra's. The difference in efficiency between small and big gliders is massive, it's much more than I expected. and yes a small glider you can't see them 100 meter away but they are cheaper, easier to handle (transportwise).

@@jacobdavidcunningham1440 I'm not expert, but yes something like that: bigger Aspect ration are possible and increased chords so higher reynolds numbers.
