Coaxial counter rotation micro motors.
 

Last few month I have built number of tiny, very light foamie models I enjoy flying in dead calm in my backyard. My first atempt to build even lighter one, I ended up at 150grams AUW but next one will bring down to 100, my target min. limit for outdoor flying.
With most of these light builds I find the single prop power creates lot of unwanted torques that makes 3/D performance slightly more challenging, so I would like to get a hands on one of these "Coaxial" ones, which are almost unheard off in this country after some search.
Any recommendation for the brand, availability and their reliability most welcomed.

Well over 200 gramer.

First built at 150g, next one will be 100 or 2 grams bellow.
Anyone using the "Dualsky XM 2203 TY -24 CR"?

It seems like these coaxial motors are non-existent on this site, just completed another micro light creation, my plan to bring it down to 100 grams was bit of wishfull thinking thanks to its larger size, but one of the next ones will come much closer or even below.
Hopefully by that time I get a hand on one of these coax beauties.

My latest creation at 86x100cm, (S/L), with 4g/dm wing loading. The rear one is 5.5g/dm. - or ~1.8oz/foot2
