I replaced some steel spacers on the FRED undercarriage with aluminium ones that took me all day to lathe up. About 6 hours work to do it but I've saved a massive 4.5 oz!
Mt wife said that having a poo before every flight would've saved more weight.

Every little helps

I took advice from Mike Birchill (G-PFAF) and cut all but the last 2 exposed threads off of all the bolts and saved about another pound of weight. Strange that the FRED plans still allow commercial grade bolts, although I have changed them ALL for AN hardware for the sake of simplicity. I'm lucky to have access to a few places locally where nuts and bolts regularly fall off of the shelves and roll out of the door.

Changing from cast iron Lambretta wheels to alloy AZUSA 8 inch wheels saved 14.5 lbs per side, I kid you not!

42 grammes in wheel-half bolts. 6 bolts at 7 grammes lighter per bolt. I wonder why they supply them about 8 threads too long?

I reckon those Asuza wheels are going to double your insurance premium

Howzat? Is there some story there or is it just the value of them???

Thought those wheels would be so expensive they'd to be worth about the same as the rest of the plane
