New to gas...
How do you attach a spinner to this ?
My large glow stuff had a nut that screwed onto the shaft with a single hole for the prop. The spinner screwed into that...

You have to replace the center bolt with one that is threaded in the center for spinner bolt,

Or simply use a coloured plastic spinner of your choice that snaps into the back plate like a Goldberg or that one that is attached to the backplate by screws like a Du Bro.

I really wouldn't recommend using a plastic spinner with a gas engine. I've seen to many engines backfire and shatter a plastic spinner. I know these newer ignitions are supposed to stop that from happening, but a little bit of prevention goes a long ways. I generally use aluminum spinners only on a gasser.

Go to TruTurn.com. They have spinner bolts for eveything.

Thanks for the link.....
Do I have to drill holes for the three small bolts?

No, the only bolt that will have a center hole tapped is the big bolt in the center.

Nitro,

Thanks for this bit of information re the use of plastic spinners as I normally use then on my gssers. My engines are in the 20-30cc range and are fitted with EI so maybe that's why I have been okay so far, but this is good to know.


MIlton,

Any advice that helps to make our sport safer should never ruffle one's feathers.

Okay...
I am lost again
The back plate for the spinner fits over the shaft, then the prop, then the new spinner bolt.
Won't the three small bolts in the picture of the FTL hit the back plate?

I missunderstood you before. Yes you will have to drill holes through the backplate for these the same as you will need to drill your prop.

A drill jig works great for this.

Drill jig?????

Here is a link to an example of one. You will need to get the proper one to fit your engine if you decide to get one.

Or you could have somebody make you one....a friend that's a machinest.

I can't understand the logic behind these relatively small engines having multiple prop bolts while much larger displacement engines such as the Zenoahs and others make do and without compromising their safety with a single prop bolt, or is it just a case of " monkey see monkey do ".

Perhaps it is intended to give the visual impression of being more like the "big boy" engines, so they'll be taken more seriously.

karolh

That's a possibility too.

Considering how many Zenoahs and Fuji's I have seen spit props because of a backfire, or a flame out, I'd say the multiple bolt hubs are a great inclusion on small gassers.

Drill the prop out to accept the center bolt then use the prop washer as a drill jig.Dont need to buy anything.
