2022/01/01 -> New project! "diet"

Thinking about where possible to save some gramms bcus every single minus gramm is very inportant for brushed!
Start!
69,1 gramm - Ant lite version (prop: black 75mm 0,83g/p)
68,9 gramm - Foxeer Pico version (prop: red 75mm 0,74g/p)
68,1 gramm - Runcam Nano3 (prop: black 75mm 0,83g/p)

Target is... can be under 60gramm!

first

  • have to change top plate! result: -3gramm
    from original thick: 2mm, weight: 3,6g
    into FC adapter thick: 0,5mm, weight: 0,4/0,6g

others

  • sorter antenna! result: -0,3g
    cut Zip Self-Lock,
  • sorter landing gird! result: -1,5g
    cut rubber cup from 24mm into 19mm,
  • the best long of rubber cup for:
    1S=15mm
    2S=19mm
  • change rubber for battery! result: -1g
    old: 1,28g
    new: 0,19g,
  • propeller?! result -1,2g
    black 75mm weight: 0,83g/p
    gemfan 75mm weight: 0,52g/p
    result 4x (0,83-0,52) = 4x0,31 -> -1,2g

possible: 3+0,3+1,5+1+1,2 -> 7gramm+?

Finally result of diet:
Version Ant lite: 69,1g -> 62,2g (- 6,9gramm)
Version Foxeer Pico: 68,9g -> 61,8g (- 7,1gramm)
Version Runcam Nano3: 68,1g -> 62,1g (- 6gramm)

Longest fly time and more acceleration and agility! :)
