well you should probably choose a motor and then match the prop to it, then you can see how much trust you have. but anyways this prop is awesome, very nicely built. i have 2 of them and is really sweet
The difference between a conventional pulling prop and a pusher prop is the direction of the blades. A pusher prop pushes a plane and the motor and prop are mounted on the back of the plane, instead of the nose. Pulling props pull air and are commonly mounted with the engine on the front of the aircraft
same as most other MAS props, great durability but quality could use a bit of improvement, in terms of just removing the flash instead of having the customer do it. But balance is pretty good, a bit off but shouldnt affect performance too much.
A very well made prop, it has all the inserts you will need for different size shafts. It says on the instructions to scrape the edge of the blade with a hobby knife to remove the excess plastic so you will have to balance the prop.
