Looking into this further.
I have a 900 & 800 front wings.
1. Marek - can you compare the takeoff speed of your dragonfly vs slingshot i99 (I used to have a i99 so I can relate to that takeoff speed)?
I understand that the dragonfly will be faster but I am wondering about takeoff speed. From your graph it looks like the i99 takeoff is a touch earlier?
2. I have the + 115 fuse. Should I still use 71mm space or could I reduce the gap? (photo below with 71 mm space)
3. How does it turn? Does it move the centre of lift back somewhat? Any weird control issues?
4. I would probably 3d print a spacer to put back in if I wanted to run it as a single foil.
Thanks!
Joe
