Hello everyone.
And thankyou for a wonderfull and helpfull website Glenn.
Im wondering if anyone has any idea on how long the f+p motors last in the sun?
I cant imagine that they have any uv stabilizers in the plastic.
Has anyone tried making a cowling yet?
I have a few 20ltr drums that fit over the motor with about 5mm clearance but am worried about heat and there not very aerodynamic.

Hi Sangeff, I've recently noticed that afew cracks are appearing in my plastic rotor on the exterior--don't kow if it's the retrofitted neo's that are doing it or caused it --or it's breaking down under the uv.

I will be painting mine soon and now have a question --what is the best type of paint to use-I think electricians paint that orange pvc electrical conduit (above ground) with a paint ----at least that's what the code requires them to do (seldom see them do it )

 

The drum thing seems a good idea if you can manage to fix it very securely so that it dosen't vibrate and rattle.

cheers

Thanks for the offer ian but ive managed to collect 20 of them so i should be rite for while ill probably just give them a good coat of paint and then make a curved roof for each one to help keep the rain out as well.
The alloy rotor sounds interesting let us know how you go.
Thanks
Geoff

I have seen the UV damage on one of my hubs. About 2 years worth of sun light, and the plastic was starting to get fine cracks. The top layer was starting to crumble, like a fine powder.

I now paint my hubs in enamel, Killrust or engine paint.
