MAS 3-Blade is my best propeller option
Review by Guapoman2000 on 17 Jan 2020review stating MAS 3-Blade is my best propeller option
I use this propeller for all my Park Zone T-28 (Navy) and T-28D (Airforce) park flyer models with the 44-inch wing span. I also fly this same propeller on my Park Zone MKiV Spitfire model. It provides an amazing amount of thrust and good airspeed. It is the best for performing continuous KNIFE EDGE flight (T-28 Trojan) all around the field without missing a beat (or leaving the KNIFE EDGE) flight. This propeller is very well balanced and it is super strong. The model will be completely destroyed before this propeller breaks! guapoman2000.

Review by Davide on 29 Jun 2012review stating Nice prop
I bought this prop because I got fed up with the nicks on my much more expensive wood propellers, and thought this was a bargain. Well, it is, and so I bought two of them.
The good: 1. Both props balanced equally, so it appears that machine made props have little unit to unit variation which is a mark of quality production; 2. The blades were very firm, so I'm much disinclined to ever buy a woody again; 3. The price is very reasonable. 4. Slots in the hub for balancing, see below.
The bad: 1. The balance was fair. I used a Dubro balancer which forgives nothing, and found it needed more work. A question comes up as to how balanced a prop needs to be, but if it were perfectly balanced the price would have to cost 3x to 5x more; 2. The packaging proclaimed that it was balanced - not true.
The ugly: 1. The first prop I balanced using the "remove method" and sanded the backside of the prop blades. In my opinion, too much material had to be removed to get the job done, and the result was not attractive; 2. The second prop I balanced by the "add method" and did the job at the hub. The slots described above were tapped 10-24 (no pilot hole was required), and two set screws were installed: one 5/16" long and the second 3/8" long. The result was perfect, with no blade sanding or strength reduction. (The trick here is to place servo tape on the edge of the hub at two locations, and add brass tubing to the exposed sticky surface until the prop is balanced. Then, install the set screw and re-balance afterwhich proceed to work on the last set screw installation.)
Small airscrew props don't have the slots, but the job can still be done by installing set screws in the radial orientation, which is much easier anyway.
All of this was a lot of fun actually, and the result was very satisfying. Happy flying.
