1.5" spinners

Thanks Ian,

Who makes it?

That I don't know but this is where I got mine from

http://www.densmodelsupplies.co.uk/index.php?b=&t=&c=wheels_spinners_and_miscellaneous_accessories&s=&p=1_1/2_inch_spinner&pid=157

but they look like the Dubro spinners

I had seen the Dubro spinners but, didn't think they had a spacer small enough to neck down to the 5-40 stud.

How did you make it work?

Ron

Didn't get spacers with my spinners - hole slightly larger but easy to centre.



This is obviously not a Dubro spinner - the plate is not between the propellor and the engine.

When I search for 1 1/2 " Model Aircraft spinner - I find loads like the one I have but in the UK. There is not makers description and they are shipped "loose" - no packets with labels.

According to this site the manufacturer is Radio Active

Sorry if this doesn't help.

Thanks!!! To the both of you.

PM sent (I don't know the manufacturer of mine either) It's OLD.. and I got it with some other used parts years ago. Could be a Dubro. Needs a 1/4" x 1/8" bushing (preferably the same thickness of the plate..) and fender-washer to fit a 5-40 screw/stud.

The best spinners that I've seen are the Aluminum ones from MP Jet, these are direct dropins on the Norvel engines too.

Second best, I guess, are the ones from Mecoa with an aluminum backplate, these also comes with adapters for cox engines.

The all plastic spinners I wouldn't trust for high revving applications....

Thanks Kris!

In a discussion with Roddie, he brought up that that rotational mass might load down the engine. It's a valid point, does anyone else care to weigh in?

I want the spinner to blend into the nacelle for a streamlining effect as well as an aesthetic look.

Ron

Rotational mass cannot put any load on an engine at a constant rpm. I principle the engine could accelerate a little slower but the weight of the prop is more important as it has a larger diameter and a larger inertial moment.

Aesthetics and streamlining is what the spinners are for...
