Hey folks... Do you have to use a spinner on your planes, is there any problems if you dont???

Thanks...

hi,

if your using a starter its nice to have a spinner, much easier to keep the starter on it then just a the nut/prop. safer also.

but if your using a chicken stick no need for a spinner at all.

Thanks Bass.... I am using a chicken stick on a well broken in 4 stroke 120..... Without the spinner and my prop is balanced the vibrations are down to almost nothing..

Nah, spinners are optional. They look good on some planes and are easier to use a starter with. I have an Ultra Stick without a spinner and I just turn the starter cone insert around.

jkovar, did you know that you can balance your spinner as well? I've done that to everyone of mine and it really makes a difference.

The spinner is more aerodynamic. It also some of the air to the outside of the prop where most of the thrust comes from. It can save the carb from snapping off in an accident.

The spinner is also a safety device.
Would you rather be hit with something round and smooth or a sharp multi-cornered device?

Some folks have reported a few hundred more RPMs using a spinner. I like spinners, especially on a 4 stroke. If it decides to hiccup in flight and the nut and jam nut loosen up and come off, there's a good chance they'll be right there in the spinner. As for using a starter, they make a silicone starter cup that you can reverse to use on a bare prop.

The 10,000 rpm razor blade worries me a lot more than the end of the shaft or the corners of the nut.

For me it all depends on the plane..

If I'm not running a full spinner I'll usually use a spinner nut.. Mostly for looks and it's easier with a starter then a hex nut.
