today i saw the first microwing in the air, it was a „goblin“. it fly with two cell li-ion battery 3000mah, a 1407 3500kv cobra. it wasnt pretty fast, but itflew for 20min and the battery past 8v, it should fly very long. flydynamics looked awesome.

i know ldarc has some 450mm wingspan wings... do you know others? 
someone have impressions about microwings?

At least according to the "Long Range Hooligans" Facebook group, the micors can be very capable. Goblin is actually quite popular for long ranging exactly because of it's efficiency. The one issue with those small ones is that they are quite unstable and get thrown around in the air quite easily. I have a 600mm wingspan wing (Mini AR Wing) and while it's a screamer and can fly really fast, it's quite tricky to keep it steady in wind.

thanks for the reply.
i tought microplanes are in general to nervous in flydynamics and have more problems about wind. i started some diffrent micro to nanowingbprojects in the past, never finished builds...
i tried a small special rtf rcplane 40g brushed and i was very surprised how it stand in the air, even in alot of wind. after i saw the nano goblin my idea about was broken. i have no idea allready and like zo explore, the nano goblin had flydinamics i would like.
i own a 680mm eachine blackewing, its in progress seems a long time, today i receive a printed motormount to add a motor which should work. i tried before with a trash motor from a rcmicroplane...
but 680mm or 600 isnt micro enough :-) im absolutly not intressted in longrange or flytimes, only flydynamics are intressting to me, nimble is nice but sensitivity about wind isnt what i would like.

my buildprojects x-/ i just try things and didnt finish, i dont own enough knowledge about, i will try to finish some, but a tiny „arf“ kit would be nice...
