I've flown the real deal, tight cockpit, but sure handled nice. Leann just steals my projects, then I have to get more. Works out pretty good! lol

Nice thing about being aircrew, and a private pilot, out on the West Coast, I had access to most manufacturers, and got a lot of test flights on various homebuilt, experimental, and new certified aircraft. We did a lot of the airshow circuit, so you end up making a lot of useful contacts.

All done except for run up on motor . I need help with prop size . the motor is a OS 91 FS surpass 4 stroke , it has a 14X8 prop on it in the pic , the manual has 4 different sizes 13.5X8 , 14X7, 15X6 and 16X6 . Will my prop I have work ? How does someone determine what size props to use from 4 or more choices? thanks Dennis Attachments:

I'm going to probably get a 14x6prop , but could someone give me a simple explanation what the difference b/w 14x8 prop (the 8 means more speed or power or something else???) I still have a hard time understanding what these #'s are? thanks Dennis

First number, of course, is the diameter, 14 indicates inches. The second number is the pitch. An 8 indicates that in one revolution of the prop, it would prescribe an arc of 8 inches. * is getting towards the sport/aerobatic range, 10 is totally sport. 6 would be more in line with a scale aircraft. As you go down in pitch, the max RPM of the motor will increase. If you know what the ideal RPM range of the motor is, and have a tachometer, you can match the right pitch prop to your motor. One thing to keep in mind, with the aircraft flying, it will turn slightly faster, normally 2-300 RPM more than being held on the ground. Once you are in the ballpark, you can experiment a bit. A 14X10 prop, for example, if it's too big, and you need to go down an inch in diameter, go up an inch in pitch, i.e. 14X11, to get a similar level of performance.

Motor is in pieces on the workbench now , hoping the vibration is from the crankshaft bearings ,it was a used motor ,waiting new front and rear bearings coming monday
thanks Dave , for your example of the 14x10 prop, should the 14x11 be a 13x11 if you drop diameter to get similar performance,
