All blades have the same size, 36cm long, aerodynamically well shaped. But. The first weighs 120g, the second 125g… And the third one 210g… This is a small problem. So what are my options now? Making a new blade would be the last option, but do I have any other options?
Drill a hole in the heaviest one then use putty to cover the hole back up. For the one that's just slightly heavier you could probably remove enough with sandpaper to even them out.
Sounds relativly easy and functionable, I'll try it in this way probably.
