I would highly recommend not using glued together props. They are so cheap that it just isn't worth the risk. Even if one of my props has a white crease mark I toss it and use a brand new one. The glue might be pretty strong, but just sticking together the prop can send it out of balance, mess with the prop's aerodynamics, and it probably also increases the chances of the prop just snapping while the plane is flying. I have been hit by spinning props, and trust me when I say that it isn't worth the risk at all, even the least powerful plane in my fleet gave me scars that I still have months later.
Never do that. It will shed the blade and it could do serious damage to a person. You're much better off buying a new prop since they are so cheap as
@Ketchup stated
while what you guys say is true, for USA.
in SA here props are not so easy to come by, pretty expensive and shipping takes some time.
i have run my motor at full throttle for 1 hour, with the glued together prop, and it was still perfectly solid.
I completely understand the risks, and i do exercise extreme caution while working around props, but it's a risk i'm willing to take.
If in the case were i fly in a crowded area, or there are any people/animals/vehicles etc, around i will not use the glued prop, but as normally i am flying in a 2 hectare field with nothing but long grass and myself in it, i feel that i can fairly safely take the risk
