Prop/ engine combo??
 

Hi there,

I am currently building a UCD 60. I have hit a snag.
What props do you guys use on a .91 engine?
I bought a 15x6 master air screw k series but found it to fat to mount on my SC .91 engine. There is not enough thread left on the propshaft to put the locknut safely on.
Can anyone reccomend a prop (similar dimensions) with a slim centre peice so that I can get my locknut on.

Any help or suggestions would be great thanks:)

I have noticed that my APC(grey) and wooden props are not as thick at the hub as MAS. You might try those.

On my smaller engines I pretty much stay with APC props. I do use MAS on trainers though because they can handle A ground strike A lot better so my students save some money.
If you really need A narrow hub prop then look for an APC Wide, it just has A W behind the size. Sometimes these are too narrow and need A shim.
