…After some sanding…
And some more sanding, feels perfect.
The repaired propeller on the prop Balancer (Du-Bro TruSpin)
It’s the repaired side that is lighter. the Putty seems to be lighter than the wood. The sanding took some tiny bit of material away, as well.
Adding very gently some clear spray paint to the lighter side, making it slightly heavier (and protecting the repaired and sanded parts again)
Done
A fresh and perfectly balanced prop, ready to fly again
