More tips on Prop spinners for a newbie wanting to build scale warbirds

[smiling albert]

Hi
Some of you may know I'm a newbie looking to build scale flying warbirds such as a Stuka,Spitfire,Hurricane
I particularly want to get the nose right so the cowl meets the spinner relatively smoothly and this all seems to revolve
(!) around the spinner.
Have already seen some threads saying it can be a nightmare balancing them and plastic spinners should be avoided for this reason ,so are aluminium ones best?
Any other experiences,tips would be greatly appreciated.
Thanks

I have 3d printed a bunch of spinners and they have proven to be the most durable part of some aircrafts, I havent balanced them and they spin smoothly. Good desing is everything for that kind of stuff.

Love to see some photos!

You can see some in the build thread of my VG-33 https://forum.flitetest.com/index.php?threads/arsenal-vg-33-c1.53560/
Im currently not home so I cant do much more but I can send you more detailed stuff in a few days

I've bought some 3" (maybe 75mm) props w/ 1mm holes IIRC that came with some cool little hubs if micro is your thing...

Sounds interesting.
Have you any pictures?

Not that its a spinner in the conventional sense but it is 3D printed and is fixed directly to the 'bell' of the brushless.

The object is to provide good a streamline, a minimal frontal area and allow cooling air through the motor.

The motor mount, also 3D printed, allows air through the bulkhead and into the fuselage although at only 65 w it does not need much air.
The spinner weighs 1.2 g, the motor mount 2.5!

That is a neat trick for smoothing the front end and making it look more scale. You got links for the STL files of those?

Found a pic of the prop I've been using on some of my my micro builds... this little foamy isn't exactly a scale build but you can see how the prop might look on something cooler! (they're cheap and they come in red and black CW/CCW sets)
