All the MPI Aluminum spinners are already cut for 2 blade propellers.
The propeller cut outs are for Xoar props, so you may need to make some minor changes to the openings.
3-blade spinner cuts are not available.
At this time, MPI ProSpin spinners are the only spinners which I recommend. They are manufactured from aluminum bar stock which is heat treated, very similar to the process which Tru-Turn uses. The quality is excellent, in my opinion it rivals that of Tru-Turn. Because these are manufactured overseas, they have excellent pricing, typically far less than 50% less expensive than Tru-Turn, and I feel that they are far and away the best choice for an aluminum spinner. All other aluminum spinner manufacturers in China that I know of cast the cones and the backplates to a rough shape, and then machine them to final shape. Casting aluminum in not good! Casting aluminum makes the aluminum porous and brittle. Due to the poor properties of the casting method, cast spinners are much thicker and heavier than those machined from quality bar stock. Cast spinner cones can crack and break easily. Cast backplates can deform easily when tightening the center screw and go out of round or can crack and break. MPI ProSpin spinners are typically 30% lighter than cast spinners. Dave Brown spinners are close in price, but only the backplates are made from barstock. The cones are not. Other spinners which are made from barstock, are very expensive as well. The only real choice is the ProSpin spinner.
Note that the Pete's Models CF spinners are about 1/2 the weight of the MPI aluminum spinners, and the MPI aluminum spinners are 10% lighter than the standard Tru-turn spinners.

WARNING - Gasoline and Turbine powered R/C model aircraft are not manufactured to withstand unlimited G's. Any R/C model aircraft can fail, be it a wing folding up or a fuselage breaking in half under too high of a load. Just as any full size aircraft, model R/C aircraft have a maximum G rating. Because you are not in the plane flying it and experiencing the G's and reading the G-meter, it is more difficult to judge the G's on the aircraft, and it is very easy to exceed the limits of the aircraft. Understand that if you perform a snap roll, parachute, wall, blender, knife edge loop, or pull hard on the elevator at almost any speed, you can be putting in excess of 15 G's, even in excess of 30 G's, and most aircraft can only designed to take 10-12 G's. If you perform any violent maneuver, you can break your plane. When I perform hard maneuvers, especially for the first time on an airframe, I am prepared for a failure and am prepared for it as best I can be. This mainly includes performing the maneuver far enough away from spectators that in event of a failure that I am not endangering others. In addition, be prepared for the manufacturer to not pay for a new airframe which is broken during flight. It is common practice for any manufacturer to not replace an airframe which breaks in the air or upon landing. I have only seen manufacturers replace airframes when they have received many of the same failures and the manufacturer determines that there was a design or manufacturing error. If you break an airframe, and you are the only one to do so, then it is probably not the fault of the manufacturer. Please fly safely, and avoid full throttle operation other than at low airspeeds.
