I didn't do what Don is goiing to do(use blindnuts on landing gear). I used nylon insert locknuts and made up my own roughly 3/4" fender washers out of aluminum plate. I saved .6 ozs over readily available steel fender washers that you can get from your local hardware store by making my own washers. It's amazing what a little weight savings here and there will do. I am still waiting from my new spinner to arrive before I finalize the location of my switch harness and battery pack. Final projected weight of my composite Brio will easily be somewhere between 10 and 10-1/4 lbs. This is a great weight considering my Temptation which is smaller weighs in at 10lbs-2ozs.
