So as I promised, here is list of electro flyers on EC:
Igor Burger: I needed to add some nose weight so I decided to replace my AXI 2826/13 by heavier Scorpion 3026/710 which has aproximately the same properties, just little heavier and theu better absorbing heat, I use 3b carbon prop 11x5 at 11000, large lipo battery 6s 2600, Jeti spin 66 and active regulation. ... I would say it worked well

Richie Kornmeier: he used his ST60 model, but his B model was electric, I am not absolutely sure with his setup, but for sure he had large 3bl wood prop 13xsomething, motor orbit XXXX and battery 6s 2600 all on constant RPM setup
Juro Vejmola: Axi 2826/13 APC 12x6 lipo, spin 66, active regulation ... sometimes doing strange noise like cats hunting mouses

, but otherwise well flying when set it VERY conservatively (I wold say almost switched off

)
Jan Skrabalek: Axi 2826/13, APC 12x6, lipo, spin 66, constant RPM - well and safe working setup
Alberto Soliera: ... I hope he will add his details himself :- ))))))
Michal Meisl (jun): Axi 2826/13 APC 12x6 lipo, spin 66, active regulation, he did few mistakes, like changed regulation without properly set parameters and so lost flight ... just junior withou coach

Peter Kapuscinsky: used his old model with 6s A123 setup with AXI 2826/13, Spin 66 and APC 12x6 at constant RPM ... he was not prepared well, because he replaced another flyer just 2 weeks before contest and he did not have enough time to prepare himsef
