This one has been through a few iterations with me. I bought it already built and it weighed around 480 grams and was a real floater. I promptly taped it up and got it up to around 700 grams. It flew well in medium conditions I even got it in a light DS circuit a couple of times. But after I ditched my Alula I wanted another floater. So off came all of the tape and it's back to around 480 grams. I now use it mainly as a thermaller or when I just want to laze around on the sky, flying nice and scale like. As an inland thermal glider it is really good and will go up on a sniff of lift. I hooked a boomer one day and had to pull it out when it got so high I was having trouble telling it's orientation. Very cool.
