Which prop/spinner nut?
engine: OS 25 LA. recommends 9x6, but Im looking for one that Is short.. heres a photo to help explain what I mean.
excuse my crude paint job.
some are really long, and some are short. I have to order them online since I don't have any local RC shops in my area. I use Greathobbies.ca and the site doesn't say how long or short that middle piece is.
I was recommended, from my previous post, to get a aluminum prop nut, because on my plastic spinner my prop nut would sometimes get lose on when I applied the starter. a 10 mm wrench fits the prop nut. I've been looking online and theres a lot of different sizes for these what do these sizes mean? and would this one fit? http://www.greathobbies.com/productinfo/?prod_id=DUB740

First, you need a prop that is for glow not electric, APC is what I use. There is a prop size range for all glow engines. If this is a new engine you need to break in the engine with a recommended size prop.
Two, a spinner for a .25, if you look at the specs on the engine it will tell you the shaft size, get on tower hobbies and look for your engine and it will tell you the shaft size and when you look on the web site that your going to order it will tell you the size the spinner will fit.

As Hawk says, the prop in your picture is intended for electric, not glow. Get a prop intended for glow of a size recommended in the instructions for running in and you should have no problem fitting.
I'm not 100% sure, but I think the thread on the small OS engines is 1/4 (though all the rest of the motor is metric). If this is not right I am sure that someone will jump in and correct!

My Feedback: (1)
Your shaftsize and thread is 1/4-28 A nine six may be a bit much but always get a selection to work with . An APC 9x4, 9x5 or 9x6 will fit without being to thick and you will have sufficient threads left over for the spinner nut.
Always remember with a spinner nut (The proper one for your engine is the one I linked in your other thread) They are designed to use no washer between the prop and the spinner nut and do not put anything between the thrust bushing/washer and the rear face of the propeller.
