aluminum spinner for 2 stroke

       Remove this ad - become a site supporter!
Can an OS .46 MAX handle a 2 aluminum spinner? I have a 12x4 prop on the engine right now, will I have to get a smaller prop to allow the engine to torque the extra waight? Thanks

Did you hear about the man that fell into the upholstery machine? He's fully recovered.

i don't think it would be a problem.aluminum is light, and the shell is very's not a structural part,only the shape counts.
on the other hand, usualy, an engine doesn't work at the uper limit in a model.
i would go for it.

Hi Jon,

You'll be fine with a 2.5in al spinner on an O.S. 46. Use the same prop.

My O.S..25 powered Typhoon has a 2.75in spinner and a 10-4. Runs great.

The extra weight of the spinner does not matter. It acts like a flywheel.

Take care,
Have fun,

No problem....I used a 2.5" tru-turn with a 46FX on an extra 300..... you will have to (carefully) enlarge the slots so the prop fits

Aluminum spinners the way to go.

I found that when I went to aluminum, I had no more balance problems. Balance the prop and forget about it. The plastic spinners supplied with the ARF's were often very cheap.

I've run one on a .46AX and it worked great.
If you're not part of the solution... you may be insoluble!
