I measured all the screws and nuts used for the entire plane and put in an order for replacement titanium and aluminum screws/nuts. I'm still waiting on some final lengths for the motor mount screws and will use aluminum ones for the front mount. On my last bipe I was able to save just under 20 grams by replacing every screw, nut and bolt with Titanium and aluminum ones. It's definitely not needed but makes it more interesting to try and save weight everywhere.
