Performance wise, the Master Air screw props stink. They are great for beginners, or for an aircraft that the prop is liable to be subject to ground hits. The MAS is not stronger than the APC by any means. The MAS has more flex over the APC due to nylon vs. composite material construction. The APC is significantly mor rigid, which makes it more brittle over the MAS. The MAS flattens out about 2 pitches with RPM. The MAS spins up faster & has better breaking features over the APC because it is lighter and flexs more. It is hard to beat the wood prop though for response rate and braking features. I run the modified Zinger 10x4 on my PBXL with a Webra 32 with a MCM. If you have added landing gear to your PBF, you're much better off with a wood prop over the MAS or APC. You can get so much better response out of the wood props, which is essential in recovery in those low low manuvers (when you 'dumb-thumb' a move )

Dave - have you tried the modified version of the Zinger according to 3Dreaming's recommendations for your Stickit? I think that you'll like it much better over the Top Flite Pwr Point.
