Hi Jeroen
"In the latest issue of Kitplanes magazine, on page
14, an example is given of drilling holes in the brake disc to save
weight. Does anyone knowwhether this is possible / advisable / plain
stupid on the Europa?"
I didn't yet see the article,
but>>>>>>>I shoehorned a 60HP YTZ250 motor in a YZ80
frame. To handle the extra speed and weight i put the discs from the YTZ
onto the ZY. The front disc was drilled, but theback was not.
Happened to be same diameter so i used the front as a drill jig and
started to drill, and drill and drill and drill, etc. etc. etc. etc. I own
a professional Darex drill sharpenerand it got a nice workout. Then
once you drill all the holes you get to deburr both sides. Many hours of
work,I forget the weight savings and it was not worth it. I don't
see why you couldn't drill disc, not worth it doing 1 hole at a time with
drill press. With a CNC perhaps.
Some weight savings ideas:
Aft
mounted battery if you are tending nose heavy
Aluminium with copper
clad cable
Odyssey PC545 battery instead of 680
Monowheel over
tri
No interior
Light panel
Go light on fill and paint on
bottom of plane
Go on a mini diet
