I am building a 3D plane and have a question. How much more does your average aluminum spinner weigh verses a plastic one? I would like an aluminum spinner but if plastic is lighter I will settle for plastic, weight is going to be very important!!

2.5in TruTurn weighs 1.9oz

if you want the absolute lightest spinner carbon fiber would be it .. or no spinner at all

I am still looking for a comparison, average plastic spinner verses average aluminum. Anyone weighed both?

I use prop nuts on my 3D planes. Maybe not as pretty but it is the lightest solution. These are all Higley.

I'm with David on this. On all my glow planes I use a Higley prop nut. After you get used to them...they look kinda "funky". The can be started with a starter and are really light.
Thanks

Plastic is lighter, look for the ones that have tha backplate lightened, also, as a weight saving freak I have to suggest a CF landing gear and a lipo with regulator for rx, 7-9gms servo for throtle; that`s the places where you can save more besides of the spinner.
