I busted about 4 or 5 props so far.
two are completely broken, the rest only have small damages.
The completely broken prop was my fault. I fired up the OpenPPG on the ground without paying attention that there are no loose straps.
The two props that have each a tiny damage, I do not really know what happend, maybe a small stone or something when launching…
Anyways, since the props are made out of wood, I thought I should be able to repair them.
Here’s the damage already “cleaned” with a sharp knife, taking away some of the wood fibre.
I forgot to take a picture of the prop with the original damage.
this is some Putty specially for wood, which I purchased in a local hardware store. Akzo Nobel is the manufacturer (they make tons of chemicals…)
Using my finger, I pushed the putty into the hole… not so easy
Here are both sides of the prop after some smoothing with a wet finger.
I tried to make sure that there is excess material everywhere, so that the next step would be sanding.
I could also let it dry and add a second and third layer of putty, should the hole be a little larger.
