Aircraft International pilot, slightly less than an ounce. I used Maudib's cockpit lightning up, only gained 3.5 ounces. But hey, a little here and a little there all adds up. Also, just before I started building I re-weighed every thing and it had lost about 6 ounces. Hopefully the balsa has dried out enough that it will not absorb near that much again.

Mine is getting a 3W 75, it was that or a G62. All I had not flying.

Blue Skies & Fair Winds,
